AFunnyKindOfFailure 01 Nov 2005 - 04:55 CarolynJohnston I was reviewing my bookmarks tonight -- sometimes I bookmark things to read later, and then forget they are there -- and I found this testimony of Dr. G. Reid Lyon, the chief of the Child Development and Behavior Branch of the National Institutes of Health, to a subcommittee of the House of Representatives. His address was about the deleterious effects on students and teachers of crummy education research. I wish I could tell when it was given -- the date isn't on the link. Lyon believes the reason seasoned teachers pay no attention to ed research is that it isn't worth paying attention to. It's worse than worthless, he claims, and he makes the case that it has to improve if it is to become trustworthy. And he offers a personal anecdote about the effect on his early career of the failure of ed research to deliver real guidance. I know first hand the devastating effect that poor quality research has on teaching practices and the trust teachers have in education research. As a young brand new third grade teacher in the mid 1970s I was responsible for teaching 28 students of varying abilities and backgrounds. Many of my students had not yet learned to read which concerned me greatly, but I was informed in my education courses and via the school philosophy that this was to be expected - children learn at their own pace. My school had also adopted a reading curriculum that was based upon the assumption that reading was a natural process, similar to learning to listen and speak. Following this curriculum, I presented reading concepts to children through exposing them to wonderful literature, and attempted to teach phonics concepts incidentally as they appeared in different stories. I also employed the oral language and writing activities that were suggested in my teacher's instructional manual. At the beginning of the year, a third of my students could not read well enough to understand what they had read. Their reading was slow and labored and they mispronounced words constantly. Their spelling was lousy. At the end of the year, the same third of my students could not read well. Their reading remained slow and effortful, the time it took to read text was so great that they could not remember what they read, and their spelling was still lousy. The only change that I could discern was that their motivation to learn to read had waned, and their self-esteem had suffered substantially. Likewise, I felt like a failure, I had let down the children I was responsible for, and I left the classroom teaching profession. I attributed my failure to the fact that I was inexperienced, which I clearly was. It was only later that I came to learn in great depth that the reading instructional approach embraced by my school was not only based upon research that was questionable at best, but that the major assumptions upon which the instructional philosophy and recommended teaching interactions rested had never been adequately tested through well designed studies. I mention this anecdote only to provide a personal explanation for why many teachers lose trust in "research" and eschew educational research findings to guide their practice. Those that stay in the profession learn to simply "wait out" the next "research-based" instructional magic bullet.Of course, it's a dubious sort of failure that leaves you a Branch Chief at the National Institutes of Health. But I do wonder if other potentially good teachers burn out as a result of having believed in, and being failed by, the unsupported theories that they learned in ed school. comments... TheShoelaceProblem 01 Nov 2005 - 13:12 CatherineJohnson Now that Doug has solved my helmet problem, * I'm hoping someone can solve my shoelace problem. A couple of years ago the then-director of special ed (we're on our 3rd in 7 years) told me to forget about teaching Andrew to tie his shoes. Forget about it as in: forget about it for good. It's not going to happen, don't speak of it again. Naturally this was my cue to decide Andrew would be learning to tie his shoes come hell or high water. [pause] Wow. Hell or high water. I've been saying hell-or-high-water most of my adult life, and until Hurricane Katrina it hadn't occurred to me what the first person to say come-hell-or-high-water was actually talking about. He was talking about teaching his autistic kid to tie his shoes in the midst of torrential rains and major flooding. Which reminds me: possibly the only good thing about ageing is that you get to find out the true meaning of sayings. Most sayings come from dogs, I find, except for the ones that come from square dancing. Wolf it down, dog your heels, dog days, dog eat dog, let sleeping dogs lie, and so on. Pretty much the whole lot. Dogs have had a big influence, being our co-evolutionists and all. What comes from square dancing, you ask? Back to square one comes from square dancing. Speaking of which, we were talking about: tying shoes Andrew is now actively interested in tying his shoes, and is making progress. But I can't remember the easy way of tying shoes his aide showed me a couple of years ago. (She's not his aide anymore, or I'd ask her.) And I can't find it on the internet. I may have now reconstructed it for myself (discovery knowledge! that's the ticket!) But if anyone knows how it's done, I'd appreciate hearing from you. ![]() *not to mention my number line problem, my fraction problem, and my distributive property problem updatewow!

IvarsPetersonAskAFriendMarketplaces 01 Nov 2005 - 15:58 CatherineJohnson Speaking of ktm readers solving people's problems, this SCIENCE NEWS article, on Ask-a-Friend Marketplaces, is interesting (subscription may be required) In a 2003 experiment, sociologist Duncan Watts of Columbia University and his coworkers used e-mail to test the notion that every person in the world can reach any other person through a chain of just a handful of social ties. In many instances, the chain fizzled out when someone failed to pass the message on. The high attrition rate demonstrated in the experiment suggests that it may be difficult to find "faraway" information in a social network. Many people may not be motivated enough to participate. To overcome this problem, the idea is to offer a reward for the information. Then, as a query is passed from person to person, each participant takes a cut. The search continues until the reward money runs out or an answer is reached. [snip] The crucial parameter describing the underlying network is its "effective branching factor." In effect, it's the average number of friends to whom a member of the network passes on a query. When the branching factor, b, is greater than 1, there exist reasonably short paths to the answer. However, if the branching factor is less than 2, the amount you have to pay in incentives to get an answer is prohibitive—even though short paths to the answer exist. The situation is much more favorable when the branching factor is greater than 2. "For a large branching factor, the propagation of queries is very efficient in its use of reward," Kleinberg and Raghavan conclude in a paper presented at the 46th Annual Symposium on Foundations of Computer Science, held recently in Pittsburgh. "By simulation, we have found that the transition at b = 2 is already apparent for rarities n of moderate size," the researchers report. A rarity of n means that one out of n members possesses the answer to a given question. So, when you're offering incentives, it's a good strategy to ask at least two friends when you need advice. Asking just one friend isn't enough to give you a reasonable chance of eventually getting an answer via some chain of acquaintances. I bet you could put together a fantastic Ask-A-Friend web site based on this principle. Sort of like eBay, only for information....and everybody gets a cut. Overnight, internet addiction could be transformed into gainful employment. comments... WhatHappenedToRecentChanges 01 Nov 2005 - 17:47 CarolynJohnston I took it out!

RudbeckiaHirtaOnCalculus 01 Nov 2005 - 18:18 CatherineJohnson ...answering these questions: In terms of teaching calculus to college freshmen, it would be easier if they had NOT taken calculus in high school. Or, rather, it would be best if the students who took calculus in high school all—or almost all—scored well enough on standardized tests so as to not retake calculus in college. It's the retaking that sucks (and the "wasted" year). Why do you say this? Are these kids hard to teach....or are you saying they're wasting their time re-taking calculus....?? And do you think it would be better to take neither of the AP calculus courses? If so, is there a math course you'd prefer these kids take senior year? The first issue is one that we read here all the time: teaching by "exposure" versus teaching to mastery. If you want the students to know calculus (not to have merely "taken" calculus), then you want them to have been in a class that expects mastery. Some high school classes do, and some high school classes don't; some college classes do, and some college classes don't. But most importantly why spend two years on a task that most students are capable of doing in one? (I believe it took Newton two years to INVENT calculus. Of course he was working on it full time because everything was closed due to some plague.) The other problem with re-teaching is that the students think they already know everything. This leads to a few common problems: the students think they know everything already, so they are reluctant to put effort into learning (coming to class, doing homework)—instead trying to get by on what they already know. If they took a sub-optimal high school calculus class, the teacher may have treated the foundational material (which is very abstract and difficult for students) as "unimportant"; the students often pick up on this attitude. During certain parts of the class, the point of the lesson is to understand a certain idea (the definition of the derivative and its connection to slope), and students who have already taken calculus will instead choose to (incorrectly) answer the question by using an easier calculation taught later in the course. (It's not that I'm against "short cuts"; the point of the lesson is to understand what's going on behind the scenes of the shorter calculation.) In terms of the AP calculus classes, I really like the BC calculus. (Biased I am, as I took BC calculus myself during the 1989-90 school year at Niskayuna High School in Niskayuna, NY.) There are very few circumstances where I would recommend AB calculus. There are some obvious ones (teacher, schedule logistics, etc.) but aside from that, the only other time I would recommend AB over BC would be for a student who has struggled greatly in precalc, who is planning on studying the humanities in college, and who is planning on attending a college where part of the gen-ed requirements can be fulfilled by scoring well on the AB calculus exam. However, a BC calculus course that prepares students to take the BC exam is a fine opportunity. In terms of 12th grade math offerings, that would be a fairly place-dependent recommendation. If the school has a corps of students who finish 11th grade ready for a real calculus course, then something like BC calc would be a canonical recommendation. Otherwise it then becomes an issue of looking at WHY aren't there students ready for 12th grade calculus (school too small for critical mass? ineffective programs? something else?) and making decisions based on that. There is a lot of interesting mathematics that can be done at the high school level, and the "right" course will depend on both the school and the students. people hate learning things all over againThe other problem with re-teaching is that the students think they already know everything. This leads to a few common problems: the students think they know everything already, so they are reluctant to put effort into learning (coming to class, doing homework)—instead trying to get by on what they already know. As far as I can tell, this is a huge, 'foundational' problem at all levels. My Singapore Math kids are in open revolt at having to learn to do bar models when they can already solve a problem doing simple calculations (i.e. subtracting). Christopher, too, runs amok whenever I ask him to 'back up' a step. My neighbor and I were talking about this one day, about why it's so aversive—and aversive is the word—to 'go back to the beginning,' or to 'do things more than one way.' I came up with a theory, which I have now forgotten. It will come back to me.discovery ≠ memoryThat's something I've been meaning to point out. I've seen constructivist educators claim that discovery is a memory aide. Something you discover for yourself you remember better. I've also seen cognitive scientists say this is rubbish, and I can tell you it's rubbish without recourse to PubMed. Nonfiction writers are constantly forgetting their discoveries (which we call 'ideas'); this is why writers carry notebooks and pencils around; this is why some writers will actually get up out of bed in the middle of the night to write down middle-of-the-night discoveries on a piece of paper. If you don't write your ideas down, they're gone. As a matter of fact, new ideas are far less sturdy than old ideas, precisely because they are new. They haven't been rehearsed, by definition.what's the code for the 'does not equal' sign?Remember: it pays to ask a question!never mindI found it herecomments...

MathematicalPrimalScreamTherapy 02 Nov 2005 - 04:50 CarolynJohnston Reading Rudbeckia's post here reminded me of my own self-teaching experience in 8th grade. My 8th grade math teacher took a few of us "math brains" aside and gave us a 9th grade textbook to work through on our own. We sat in the back of the class all year and worked on these books by ourselves, at a table. Like Rudbeckia's class, noone checked our homework and noone gave us tests. Every quarter, we got an automatic "A" on our report cards. I, being the space-cadet wonder child that I was (I honestly believed, somewhere deep down, that all this work was for the other kids but not for me), didn't do a thing all year. I thought my thoughts and dreamed my dreams. The kid who sat across from me at the table used to nag me to do something and tell me that I'd get in trouble if I didn't, but I didn't see that I was going to get into trouble at all. What trouble? I was getting As without lifting a finger, and noone was checking. Kim Osborn was her name, and she was a very earnest worker (Kim, wherever you are, you tried; it wasn't your fault). And then, of course, I got into trouble. I took the Regents 9th grade math exam, and by the skin of my teeth and the dint of some generous grading, I got a 67. My Dad hit the roof when he found out what had been going on; he had assumed I was really earning those As, and he had never been to a parent-teacher conference and talked to the math teacher. the moral of the story Don't assume that your kid can work on his or her own, even if he or she is bright. Actually, the notion that a kid will do his homework, much less teach himself first-year algebra, without being nagged and ridden is probably wrong in a lot of cases. a related thought about teaching Much later, after I got interested in the subject, I became quite a good student. I got straight As in college math, without even realizing that not everyone in my class was in the same boat. I was quite shocked when I started teaching and found that students such as I had been were rare. My office hours were filled with students who just didn't get it. I was bewildered; it hadn't been hard for me; why was it so hard for them? Obviously some of them weren't trying, but many were. Most of them couldn't make it without a lot of extra help. I was quite patient with them, but I lacked sympathy. And I wasn't the only one who lacked sympathy; everywhere I looked, the other student teachers and even professors were just as bewildered as I am by the difficulty their kids were having learning math, and by the resentment they felt toward the subject and us. In each case, you might say, we were haunted by the memory of the students that we had been. But each of us had been some teacher's dream student. I think it's the hallmark of a mature teacher that she can learn to put aside her own experiences as a learner and give the kids what they really need, whether it's more or less challenging work, or a bit more support than they themselves needed -- just as it's the hallmark of a good parent that they don't let their own experiences as children get in the way of rearing their own kids. And this works the other way too. I think a lot of what fuels the constructivist engine is the loathing that so many people in the ed business remember feeling for mathematics when they were kids. They might think that they hated it because it was plug-and-chug, drill-and-kill, sage-on-the-stage, and so forth; I suspect they really hated it because, at some point, they got left in the dust and every experience after that was one of failure. People who get through math successfully, but just don't like it well enough to pursue it further, don't have the same feelings of bitterness I so often see expressed by constructivists. Might I suggest that they, too, need to let their own childhoods go? comments... ExtremePumpkin 02 Nov 2005 - 15:16 CatherineJohnson here source: Brian Mickelthwait comments... RequestForHelpWithBarModelProblems 02 Nov 2005 - 17:33 CatherineJohnson My Singapore Math kids are in revolt because the bar model problems I've given them are too easy. I had the same problem with Christopher. In his case, I handled things by giving him enough hard bar model problems that he finally realized he couldn't do them, at which point he agreed to back up & start at the beginning. I can't do that with the Singapore Math kids because I only see them once a week for 8 weeks. Plus, they're not my kids, and I'm not their (regular) teacher. My options are limited. There are at least 3—maybe 4—kids in the class who are super-good at math. They all love the Brain Maths problems, so I may just turn the class into the Brain Maths class. That's Plan B. Plan APlan A is to bring in some problems the kids can only do using bar models (and also turn the class into the BRAIN MATHS class. I figure, if they love doing BRAIN MATHS problems, go for it.) I've just written up sheets for a Science News PuzzleZone problem that's going to be far more doable using bar models:Seven apples must be shared equally among 12 children, but no apple is to be cut into more than four parts. How would you do it? I also drew up bar models using the 'Hint' Science News gives kids to help them solve the problem. So they'll have a bunch of sheets to look at, think about, & play with while they're solving the problem. It suddenly occurred to me: these kids are nine. And: they are boys. Fine motor skills aren't their strength, except for the boy who's good at drawing. As I did with Christopher, I'm taking the fine motor aspect of learning Singapore Math out of the 'equation' for now. ![]() anyone got any good problems?If you have ideas for word problems around the level of a bright, math-savvy 9-year old that will be easier to solve with a bar model than without, I'd love to hear them. And if you have story problems you know kids this age have enjoyed doing, I'd LOVE to see them.

PuzzleZoneQuestion 02 Nov 2005 - 19:36 CatherineJohnson Feb. 9, 2005 Raincoat, Hat, and Boots A raincoat, hat, and boots were bought for $280. The raincoat cost $180 more than the hat, and the hat and the raincoat together cost $240 more than the boots. How much did each item of raingear cost? I solved this easily using algebra. But then, when I looked at Puzzle Zone's answer, I didn't have a clue what it meant. Now that I've spent some time mulling it over, I realize that I still don't completely 'have' the concept of subtraction as comparison (which I was never taught). Fooling around with bar models helped me figure it out....but even though I can now draw this, I still don't understand—verbally understand—why we are talking about buying two pairs of boots as the key to solving the problem. At the moment, there's no conceivable way I could explain this in words.

KoegelsOnTelevision 03 Nov 2005 - 02:31 CatherineJohnson Subject: Super nanny with an autistic childAIRS FRIDAY, NOVEMBER 4 "Facente Family" -- Supernanny Jo Frost teams with world-renowned autism expert Dr. Lynn Koegel to tackle the parenting issues faced by a family whose three-year-old son is an outsider in his own home. This episode of "Supernanny" airs on FRIDAY, NOVEMBER 4 (8:00-9:00 p.m. ET) on the ABC Television Network. Deirdre and Trae Facente don't know how to integrate their autistic son Tristin into their daily life with their twins, Kayla and Marlana (4). Tristin is completely non-verbal, caught up in his own world of spinning, jumping, swinging and, often, taking off his clothes. The only time he spends with his family is sitting at the dinner table. The twins, who demand much of their stay-at-home mom's attention, can't figure out how to play with their little brother. The parents are at a loss as to how to help Tristin come out of his zone and join the family. Enter Dr. Koegel and Supernanny. Together they refine the classic Supernanny methods and teach all the Facentes Dr. Koegel's inclusion and communication techniques to help engage Tristin. For example, when they introduce the new daily schedule to everyone, Dr. Koegel uses a picture board with Tristin to help him understand in a concrete way. In just a week, silent Tristin goes from zero words to speaking hundreds of times using over 20 new words. He is bursting with requests to play a favorite game, be tickled or eat a treat. Step-by- step, Jo and Dr. Koegel help the parents keep Tristin from his disruptive behaviors by including him in family chores and activities. These efforts culminate in the boy helping his dad set the table, a seemingly mundane task that is so miraculous for Tristin, it brings tears to Trae's eyes. Lynn Kern Koegel, Ph.D is one of the world's foremost experts on the treatment of autism. She and her husband, Robert L. Koegel, Ph.D., founded the renowned Koegel Autism Center at the Graduate School of Education at the University of California, Santa Barbara. She co- wrote the bestselling book on autism, Overcoming Autism: Finding the Answers, Strategies, and Hope that can Transform a Child's Life, which was recently released in paperback, and also co-authored, with Robert Koegel, the new book, Pivotal Response Treatments for Autism♥ ♥ ♥ ♥ ♥ We love these people. They are our autism gurus; they are two of the best people on earth. Their work is so brilliant, and, at the same time, so down-to-earth & heartfelt it's hard to capture in words.

I'm going to try to unearth my short piece on PRT to post tomorrow. "Pivotal response training"&mdah;the concept behind it—is probably the core concept in just undertaking one can imagine.
comments... IsSaxonPlusSingaporeTooMuch 03 Nov 2005 - 05:26 CarolynJohnston We had a request today for some information about supplementing Saxon Math with Singapore Math... I found this site several weeks ago and I LOVE IT! I started homeschooling my two sons last year after taking them out of public school. I have been using Saxon math. Last year they were in second and third grade and I had them in Saxon 2 and 3. This year, I have them both in Saxon 5/4. I like the Saxon program because it seems to be very thorough and they have plenty of practice. Neither I nor they are very strong in mental math and I have wondered about supplementing Saxon with Singapore Math. I'd like some advice on this. Would it be overkill? To let you know about where they are now: It takes them about an hour a day to do their math lessons. They are at lesson 28 in Saxon. (It's all pretty much review—nothing they haven't had before.) They have had four tests and have done well on all of them. (They both scored 100 percent on the first three.) My older son knows his multiplication facts through 12s pretty well. My younger son is shakier on these and hasn't learned sixes, eights and twelves. I tried giving them the Singapore 3a placement test and they just couldn't do it. I started giving them the Singapore 2a placement test and they are handling that fine (though with a lot of complaints because they have to THINK about what to do in the word problems.) They both like to have me walk them through problems instead of making a stab at it on their own. Thanks in advance for any help anyone can give me. DianeFirst responders on the scene (with math tourniquets) were Susan and Dan... Susan's response: A homeschooler friend of mine once told me that many homeschoolers use both Singapore and Saxon at the same time. I'm presently using Saxon as the core supplement curriculum for my public school child, but I add Singapore problems to whatever chapter I'm on. Singapore's word problems are better than any of the other books I've seen because they start with one and two steps and move up to 4+ steps by their level 5. I don't know if you've seen The Well Trained Mind book, but it has an easy to follow schedule for homeschooling all subjects throughout the years of your child. You might get some ideas of how much to do from there. Since I'm an "after-schooler," as they call me, I haven't ever looked closely at the way they set up the teaching schedule, but it looks fairly thorough.Dan's response: I haven't homeschooled, so I feel a little uncomfortable commenting...but only a little. I just wanted to ask if you were testing the multiplication (and, for that matter, addition) facts with timed tests. I'm pretty sure that timed fact tests are part of the Saxon school curriculum. It seems to be a consensus opinion here at KTM that these facts must be mastered to the point of automaticity. I certainly agree, and have found any lack of automaticity to be a major hindrance as students try to move forward.And Diane replied.. DanK, Yes, I am using timed tests for addition and subtraction, and I use multiplication fact worksheets for drill, though I don't usually time them. We are just now moving into timed multiplication tests with Saxon. SusanS, I have read "The Well Trained Mind" and I just revisited her suggestions for scheduling. An hour a day for math seems pretty typical for what most other homeschoolers I know are doing. I am leaning towards getting Singapore and supplementing with it. Some of my friends who use Saxon with their kids just have the child work every other problem. I've been having my sons do every problem, and, as I commented earlier, it takes them about an hour. I don't want them to get overwhelmed by having an hour and a half of math every day, so I guess I would have to cut out some of the practice problems in Saxon.So I'll weigh in now with a few thoughts... I think an amalgam of Saxon and Singapore is a good choice for homeschooling. With Saxon, especially in the early grades, you can be sure that you're not missing out on any essential skills. I think Singapore has a good emphasis on word problems, and I like the way they get kids thinking algebraically very early. I home-supplemented my son a lot the last two years (we had a constructivist curriculum in 4th and 5th grade—Everyday Math), and even though I'm knowledgeable about math, there were days when I felt up to the task of 'constructing his curriculum' (so to speak) and days when I just didn't. Saxon is a great support for homeschoolers who don't want to be carefully preparing their kids' lessons every day. Singapore takes a greater background knowledge of math, and is much harder for the kids to do independently than Saxon, so to do Singapore, you'll be making a commitment to get really involved with your kids' math. Not every homeschooler wants to do this. I'd be reluctant to cut out every other Saxon problem on a regular basis, because I think those mixed practice problem sets are the genius of Saxon. They'll revisit a skill intermittently, and if your kids are only doing even problems, they'll miss getting the practice they need if the skill only appears in odd problems (it would be genius indeed if they had enough forethought to put a given skill alternately in even and odd problems!). You could start by trying to add Singapore word problems to each math session, and see whether that worked; you might find the kids tolerate it pretty easily. If not, you might try switching off days. You wouldn't get through either curriculum as fast, but Saxon has a lot of repetition from one year to the next, so even if you didn't get all the way through a Saxon book you'd have little cause for worry. Another thing you might consider doing is making Saxon your main text, and supplementing from one of the Singapore books that specializes in word problems, since that's where I think Singapore really has the most to offer. Singapore has a workbook series called Challenging Word Problems Books 1 - 6 ($7.80 plus shipping; 129 pages), in a U.S. (as opposed to British English) edition. You can start at the workbook that's at the level your kids placed into; the problems are marked at a mixture of difficulty levels. This is definitely what I would do if I were constructing a homeschool program. One more thought—my son, who has Asperger's Syndrome, got balky in second grade about doing math timed tests. He would basically refuse to deal with them, in class; although he knew the facts, he wouldn't do the timed tests because he was reluctant to deal with the time pressure. We ended up doing some heavy bribing to get him to move on those tests (once he did, he was fine). I think adding the time pressure factor is important to nudge the kids toward automaticity. Rewards in the form of treats or outings or privileges are good, I think. Competition can also be good, if it's friendly competition and not cutthroat (and if they're siblings that close in age, it could get ugly). comments...

BrianMickelthwaitOnKumon 03 Nov 2005 - 18:14 CatherineJohnson I'm in the middle of reading Brian Micklethwait's terrific article about his experience as a KUMON instructor, but had to stop and post this passage: There is also in Kumon what I think of as a very Japanese emphasis on the physical process of drawing the numbers and on physically handling the world generally. (Think of the Japanese fascination with hand-done graphics.) One of the ancillary games we get the children to play is simply placing numbers on a number board. This doesn’t just help them to understand numbers. It also helps them to get better at simply handling things, while thinking at the same time. As with so much of Kumon, doing the number board so that every number is where it should be is in principle very easy, so no child is humiliated by not being able to do it. But doing it fast isn’t so easy, so the cleverer ones are kept interested. (We also give the cleverer ones more complicated things, like “leave on the board only those numbers divisible by 3”.) This emphasis on the physical handling of the world also explains, I think, why the Kumon people are so reluctant to get involved with computers. To me, an Anglo-Saxon techno-nerd, Kumon absolutely shouts computers. Each child doing an individually selected clutch of repetitive problems. Relentless and potentially very tedious marking. Even more tedious analysis to tell you what each child should be doing next. A huge apparatus of collective, centralised analysis to see which methods work best and to tell the rest of the world. This is surely the sort of stuff that computers — and their recent combined offspring, the Internet — were invented to supervise. But I sense that the Kumon people resist such notions. There’s so far been no mention of computers in any of the Kumon back-up or sales literature that I’ve seen. Computers, I hear them saying, would only complicate things. I've come to believe that paper-and-pencil math is math—that there's something necessary, at least when you're learning,* about the experience of actually holding a pencil or a pen in your hand and solving problems. Carolyn talks about the craft of math; Temple repeatedly & chronically encounters people who've learned to create scale drawings on computers and, as a direct result, cannot construct scale drawings. (Temple believes that the visusal processing and motor systems in the brain are connected. I won't be surprised to learn that she's right.) I've been surprised at how unmoved Americans are by the Singapore bar models. I fell in love the instant I saw them, and wanted to draw them. With Sybilla Beckmann, I think the bar models are probably the reason for the Singapore curriculum's success. I've mentioned several times that I've worked at least 300 bar model problems. I've said, too, that doing this changed my brain. I'd put money on it. The thing is, I really don't know why this should be the case. I'd been thinking maybe they develop spatial reasoning, which is connected to mathematical ability. It hadn't occurred to me that bar models might work simply because they involve lots more pencil-and-paper work than the traditional U.S. math curriculum. But the explanation may be as simple as that. When I first started drawing bar models, I badly wanted to paint one. I wanted to do a big, bold 'blow-up' of a Singapore bar model in oil, and hang it on the wall. Maybe one day I will. what is the opposite of a fount of wisdom?Here's Steve Leinwand:Shouldn't we be as eager to end our obsessive love affair with pencil-and-paper computation as we were to move on from outhouses and sundials? The answer is no. *Temple says that older people who learned to draw by hand & then switched to CAD have no problems at all. The problems turn up strictly in the work of younger employees, who've never done physical scale drawing using pencil and paper. Swoop and Swoop the craft of math comments... SusanOnBarModels 03 Nov 2005 - 20:54 CatherineJohnson One of the things I've found interesting about the bar models is how much of a bridge it is from the pictures to the abstract. I know we've said that it is abstract, yet it is a picture. Like the number line, it walks you one step closer to where you're going. I think mathematical people might have trouble realizing what a lightbulb moment they can provide. I'll use an example that is and isn't very typical. My 8th grade LD son works at anywhere from a 6th grade level in math to a 3rd grade, depending on what mood he's in. He has an expressive language disorder and so language often confuses him much more than it would the regular kid. He will never, ever ask for an explanation because he already feels stupid, so we have a lot of trouble trying to find out what it is about something that he doesn't understand. While I've been using the Saxon 6/5 consistently, I supplement that with Singapore 3 word problems out of the textbook, workbook, or word problem book. I think he could go to 4, but I want him to feel confident for a bit longer and I also want him to get used to drawing out the bar models for easier problems so that when we "graduate" to more difficult problems he will have a good familiarity with them. The other day he had a word problem about finding the profit of something. It was something about some kid having something for a certain price and then selling it for another. What was his profit? Well he saw the increased price and the word profit. This was out of Saxon and so the the book said something like, "Use a subraction pattern to solve." This confused him even more because he was focused on the number increasing in size and so got lost in the words. It would have been easy to just say, "You find the profit by subracting the original price from the new one," but I decided to just draw a comparison bar model showing the two prices and the unknown. Immediately, he saw what it was because he's done a million bar models for subraction problems. It was interesting how completely he understood his mistake by the visual. It would have taken me several minutes of explaining and doing more "profit" problems before he would have gotten it. We're moving into division and fraction word problems and I think his understanding is going to be highly enhanced due to the constant bar model use. I wish it had been done all along. comments... HowToWriteAlgebraEquations 03 Nov 2005 - 23:35 CatherineJohnson Christopher's friend Marc just asked me for help writing equations for word problems. Here's the question. Is it the case that you can't write something like: 3 + 5 = x Russian Math says the convention is to have the variable on the lefthand side of the equation. However, Prentice-Hall seems to want not only the variable on the left-hand side, but also one of the numbers. To pass muster you'd have to write: x - 3 = 5 That seems wrong to me, and in fact, Pre-Algebra: An Accelerated Course by Mary Dolciani has one equation in the answer key in which the variable is isolated on the left side of the equation. What is the convention? Meanwhile Marc's dad told him, 'Just write the equation in the most complicated way you can think how.' Marc is good at math, but even he was a little befuddled by that. I came up with: Write it whatever way makes sense, then flip it. That worked for Marc, so he is now writing the equation the way it makes sense, then inversing it. "I can inverse it," were his exact words. I have a sneaking suspicion this is the kind of homework scene that led people to think Reform Math might be a good idea..... comments...

SheepAndDucksAndBarModels 04 Nov 2005 - 04:54 CarolynJohnston I decided to try the sheep-and-duck problem tonight, using bar models. I had previously thought it was un-bar-modellable, but I was wrong, as Nicksmama pointed out (of course, knowing that something can be done is more than half of what's necessary to do it yourself). Here's the problem. There are three times as many ducks as sheep on a farm. All the ducks and sheep have 2400 feet altogether. How many more ducks than sheep are there?I instantly drew the right picture, and as soon as I had drawn it I realized it was the right picture. But it took me a good 5 minutes more to figure out why it was the right picture, and follow through. The whole time I was trying to put this picture into words, and figure out exactly what the unknowns in the problem should be, the part of my brain that drew the picture -- call it my right brain, because that's what I think it was -- was 'talking' to my left brain, telling it that it was just being slow and stupid. It was a strange experience. I'll try to describe the process. I sat down with pencil and paper, and drew the following picture:
The blue bar represented the sheep, and the yellow ones represented the ducks. There are three times as many ducks. So far so good.
Then I added a few lines and got the following picture. I knew this picture was important. I stared at it for a long time before figuring out (i.e., verbalizing) why that was so.
Finally it dawned on me. I was splitting the sheep blocks into 4 bins, one for each foot, and the duck blocks into 2 bins, one for each foot (I know, I sound like Dr. Seuss. "She bins sheep blocks, truck bins duck blocks").
So what did these bins that I'd drawn actually represent? A minute later my left brain caught up; I had changed my bar from a bar representing ducks and sheep, to a bar representing feet. And pretty clearly that first blue bin represented the number of sheep's left front feet, which was the same as the number of sheep. I called this x.
I am embarrassed to admit that I stared at it for a while longer before realizing that each of the bins I'd split the bar into had the same number of feet in it!
So x, the number of sheep, had to satisfy 10x=2400, the total number of feet. Therefore the number of sheep was 240.
My right brain has been feeling smug for a good fifteen minutes now. I honestly haven't had such a Drawing on the Right Side of the Brain moment since I first did the exercises in that excellent book, when I was twenty.
an apology I owe Catherine two apologies, actually; one for telling her that this sort of problem was probably un-bar-modellable, and the other for doubting her claims that bar models are something special. They are something special, apparently, and if my right brain could talk, it would tell you why. comments... TimssDeclineInMathScoresByAge 04 Nov 2005 - 16:50 CatherineJohnson Just back from today's Coffee With Principal Fried, and I am moved to post this chart: ![]() source: The Seeds of Growth by Eric Hanushek I am also moved to re-post this chart:
I predict zero improvement in Irvington math a Kitchen Table Math playlet characters:MePrincipal Fried & Assistant Principal Raina Kor assorted Irvington Middle School mothers & 1 father Me: U.S. math achievement, Irvington math achievement, blah blah blah Principal Fried & Assistant Principal Raina Kor: You can't look at the TIMSS scores. They're comparing apples and oranges. Me: The samples are matched. It's not apples and oranges. PF & APK: Their school systems are completely different. Me: The samples are matched. PF & APK: You can't compare American schools to foreign schools. Me: At the KIPP Academy 80% of all 8th graders pass the Regents. PF & APK: That's a private school. Me: It's a public school. The student body is disadvantaged black & Hispanic kids from the Bronx who come to school not knowing their multiplication tables. 80% of their 8th graders pass the Regents. PF & APK: I don't know what you're talking about. 100% of our kids pass the Regents. Me: Only 30% of our 8th graders take the Regents. PF & APK: I don't know what you're talking about. Where'd you get that figure? Anyway, Regents A doesn't mean anything; it's all being changed. Me: 100% of 30% is a smaller number than 80% of 100%. PF & APK: I came from a school where everyone took Regents A after 8th grade. So I know. Me: speechless PF & APK: You don't have to tell me we're behind in math & science. All you have to do is read Tom Friedman to know we're behind in math & science. But their school systems are completely different. Most of the population in India is poor and uneducated. Me: Compare an American child with a high SES to a Singapore child with high SES and the American child does worse. Lots worse. PF & APK: Apples and oranges.....different thing.....not the same..... Me: KIPP Academy! KIPP Academy! Help! Help! Hair on fire! other parents jump in Middle School Mom: The KIPP Academy picks who they want in the school. Me: The KIPP Academy is a public school that is open to all. MSM: They don't get all their money from the taxpayers. Me: They raise some private funds, yes. They spend $9,900 per student. We spend $18,000. They have 80% of their 8th graders passing Regents A; we have 30% of our 8th graders passing Regents A. MSM: They raise money. That's why they have to have their 8th graders passing Regents. They have to show results. Me: speechless lone Irvington Middle School dad (slim, long-ish grey hair, British accent): I'd like to follow up on her point. I have no concerns about my children academically. They'll go to university; I have no concerns. What I am concerned about is our competitiveness in math and science. My wife teaches at Mount Sinai, and all of the faculty are Asian. What I want to know is, How do we broaden our children's experience of math? How do we give them hands-on experience? How do we show them you can use math to measure a room? PF & APK: You won't get an argument from me! I believe in hands-on. I know we can do more of it! etc., etc., ending with: PF & APK:, looking at Me: I think we agree. Me: We don't agree. THE END the bad news The bad news is: all the other Irvington moms are worked up about English language arts. Specifically: writing. Apparently, our writing instruction sucks eggs I had no idea! I had no idea, because I've spent the past year obsessing over math. I must say, I could have known how bad the writing situation was if I'd wanted to. After all, I was having parents tell me they'd pulled their kids out of the Irvington public schools to send them to The Masters School (cost: $26,000/year) because the writing curriculum in Irvington sucks eggs. That's a clue. Ask these parents what The Masters School's math curriculum is and they say, "I don't know." They always say "I don't know." The writing curriculum in Irvington is so lousy they aren't even thinking about math. So, truth be told, I could have known all about Irvington's bad writing instruction if I'd wanted to know. I didn't want to know. As of today, however, I've got the gorey details, some of them, anyway. Apparently, what's happening with the writing curriculum is that the middle school kids get to high school thinking they're good in English, and the AP teachers won't let them in their courses. The mom who was most exercised about this told me one teacher said the middle school kids come in unable to write a grammatical sentence. This particular mom also raised the issue of middle school kids writing memoirs year in and year out. She's right about that one. Christopher has written a memoir for the past 3 years running. Then his first big writing assignment this year, from my personal favorite, Mrs. Roth, was a short story. Yeah, that'll get him into Harvard. (see Mrs. Roth here) The English-Language-Arts mom was given the same treatment I was: I don't know what you're talking about, I don't know where you got that information, the 6th grade English program is excellent; it's the 7th and 8th grade programs that need work, etc. She got the same exact lack-of-support from the other moms, too. This is a Universal Feature of Irvington parents, it seems. The minute someone raises a concern, all the other parents jump in to protest that their child's experience has been completely different. Their child's experience has been excellent. in conclusion We're not going anywhere with math. And I'm going to have to teach Christopher how to write. We need KUMON for expository writing. Apparently I'm going to have to invent it. the actual good news There were good things, too. Raina Kor is a hoot. Plain-spoken, direct, funny. She and Scott Fried both loathed the motivational speaker and said so, a point in their favor. Unfortunately, the moms all loved the motivational speaker, and apparently their kids loved the motivational speaker, too. Everyone loved the motivational speaker so much that people were talking all at once, sharing their stories of how much better their children felt after listening to the motivational speaker, and what their children came home and said about the speaker. Throughout this explosion of enthusiasm the two principals sank deeper into their armchairs, shrugging & voicing skepticism. Finally I said, "I thought the guy was an idiot," and Principal Fried said, "See, I told you we agreed." Good one. They're going to do nothing about math, apart from (I assume) crush out the last remaining forms of tracking, but they are going to work on finally integrating the curriculum in grades K-12; they also want to do value-added assessments, and look at longitudinal data. Good. I piped up and said that 'looking at data' will be meaningless if we don't have any concept of tests for significance, confounding variables, and the like, and they both readily agreed—and when I say 'readily agreed' I mean they took the point. They continued to take my point after I illustrated it by saying that our Vice Superintendent for Curriculum had sent me a letter telling me the TONYSS scores had gone up, so TRAILBLAZERS is working. That is raw data, I said. They agreed. Good. So....there will be improvements, but not in math. There's virtually no parent support for a strong math curriculum, and the one parent in today's group who was aware that we're getting our heads handed to us on a plate is a constructivist. On back to school night he asked the math teacher, 'What are you doing to show the students there is more than one way to solve a problem?' Plus he's just moved to Irvington from the city, where his children attended the Columbia University lab school. I'll be getting no help from that quarter. it's the culture, stupid Stevenson & Stigler on the two cultures: For the Asian cultures that we have studied, the goal of elementary school education is unambiguous: to teach children academic skills and knowledge—how to read, to write, to apply mathematics, to know something of history and government, and so on. Americans lack this clarity. Because of the belief that not every child is capable of mastering the academic curriculum, and because of a commitment to provide schooling for all children, Americans find it hard to decide what it is they expect from the nations’s schools. One reason they are unwilling to define the goal of education narrowly as academic excellence is that they believe that only some children are capable of achieving it. As an alternative, many Americans place a higher priority on life adjustment and the enhancement of self-esteem than on academic learning. source: Which, of course, was the message of today's Coffee with Principal Fried and Vice principal Raina Kor. The one program the mothers loved unreservedly was Jim Tumon, youth motivational speaker. Jim Tumon was sponsored by the PTSA, not the school. The vice principal, a game sort of person, took a stab at debunking the guy. "I don't see that the fact that a child enjoyed something automatically means it's a good program," she said. "If you're doing a unit on American colonial history & the teacher has the kids churning butter in class because they churned butter back in colonial days, and all the kids had fun churning butter, does that mean butter churning belongs in school?" No one even heard her say this. They were all too busy talking about the speaker. The good news about Irvington parents is that they do believe all children can learn to write well. They believe it's the school's responsibility to teach their children to write well. They're right about that, and they'll hammer away on it until our kids are taught to write well. And Irvington parents can hammer. The reason we have foreign language instruction starting in 4th grade is that a group of them hammered the issue for 8 years. As for me, I will carry on in my Quixotic quest for excellent math instruction for all. If history is a guide, 5 or 10 years from now my views will be everyone else's views, too. We'll see. linking decline in high school scores to elementary school research on summer regression the time costs of not teaching to mastery comments...

I'm actually serious about that, and I'll be interested to see how other folks feel. The EconoLog has a long discussion thread here that's probably interesting. (Haven't read yet, but I will.) from the Acknowledgments: This book is based on an extensive program of research conducted over the past ten years. During that time period, we surveyed more than 20,000 teenagers from nine high schools and spoke with hundreds of their parents and dozens of their teachers....The project was a collaborative effort that involved three universities and research teams...An intensive longitudinal study involving nine research sites and thousands of participants comes with a large price tage. We gratefully acknowledge the financial generosity of the following organizations...the William T. Grant Foundation, the Spencer Foundation, the Office of Educational Research and Improvement of the U.S. Department of Education, the Lilly Endowment, the Carnegie Corporation of New York. I think every word of this book is true. Basically. And yet I disagree with his conclusion that school reform not only has failed, but must fail. (Have I mentioned I Am A Real American?) That's the $60,000 question, but just in terms of my own life, this book, along with The Learning Gap by Harold Stevenson and James Stigler clear things up for me. Carolyn and I were talking about the Russian constructivists a couple of nights ago—the Russian constructivists & de Saussure. De Saussure said 'meaning comes from difference'; the Russian constructivists believed that art was 'the familiar made strange.' Both of those slogans are true for me, and these two books, for me, defamiliarize American schools just enough so that I feel, for the first time, that I see our situation with some clarity. Looking forward to hearing what everyone else thinks. updateThe EconoLog thread isn't worth your time.

AsianWhiteIQDifference 04 Nov 2005 - 23:47 CatherineJohnson OK, Ken thinks he's so smart with his fancy shmancy four color chart. Well, hah! I am gonna drop kick that chart right outta here, AND I am gonna CHEAT to do it. Because I'm ruthless. from Stevenson & Stigler: The claim that Japanese students are more intelligent than American students has been made by the Irish psychologist Richard Lynn, whose work was publicized several years ago in the cover story of a national magazine. Using American norms, Lynn computed Japanese children’s scores on a commonly used test of intelligence. On this scale, Japanese children’s average IQ was significantly above the American average. Lynn’s claims, if correct, would add greatly to our understanding of cultural differences in achievement, but as another publication has pointed out, they are wrong. Asian children may learn more during their school years, but their capacity for learning—which is what intelligence tests attempt to measure—does not different from that of American children. The fundamental flaw in Lynn’s report was his failure to consider two important variables: location of residence (urban versus rural) and socioeconomic status of the children’s families. One of the consistent findings since intelligence tests were devised nearly a century ago has been the large differences between IQ scores of city children and children living in remote villages, and between children from upper-income families and from disadvantaged homes. Lynn did not gather any of his information himself, but instead relied on the norms of the test that were published in the test manual. His choice was unfortunate. Because intelligence tests in Japan are used primarily in large cities, only urban children had been tested to established the norms. Moreover, no attention had been paid to the necessity of selecting a representative sample of children from each Japanese city. The norms for the American test, by contrast, were based on a truly representative sample of urban and rural children of all socioeconomic levels. We can do more than criticize Lynn’s methodology. Data we obtained from an intelligence test given to the children in our 1980 study contradict his claims. The test, constructed especially for use in Japan, Taiwan, and the United States, included items tapping the children’s vocabulary, general information, memory, spatial, and perceptual skills, ability to use a code, and so on—all topics not explicitly taught in school. As with the mathematics tests, we developed these items with a team of researchers from each of the cultures. Contrary to what would be expected if cross-cultural differences in general intelligence could explain the striking differences in achievement, we found little overall difference in the levels of cognitive functioning of children across the three cultures. American children did not display lower intellectual abilities than Chinese and Japanese children. Scores for the individual children from each culture on the different types of items were not identical, but by the fifth grade the scores for the total test did not different significantly from one culture to another. Children in each culture displayed slightly different cognitive strengths and weaknesses, but by the time they were enrolled in the fifth grade, the most notable feature was the similarity of their performance. ♦ ♦ ♦ ♦ ♦ from Count down: The Race for Beautiful Solutions at the International Mathematical Olympiad: Questions about the academic achievements of Asian Americans are not limited to math competitions. The group has a reputation as a ‘model minority’ that excels academically. Asian Americans are overrepresented in gifted and talented classes from elementary school through high school. Compared with all other ethnic groups, including European Americans, Asian Americans have higher rates of graduation from high school, college matriculation, and graduation from college. One possible explanation is that people with Asian ancestors are biologically smarter…. [snip] Think about the three Asian Americans on the team representing the United States at the Forty-second Olympiad. All were born outside the United States. Tiankai came from China; Ian was born in Australia, though his parents had emigrated from Vietnam; and David had emigrated from Korea. [snip] By the third generation most Asian American kids are more American than Asian. First-generation immigrants from Asia tend to receive grades at school that are higher than the average, but over the generations he grades regress to the mean. On many measures of health, attitude, and well-being, recent immigrants score far higher than families that have been in the United States for longer periods. The ethnic makeup of U.S. Olympiad teams clearly shows this effect. Most Japanese families in the United States, for example, have been in the country since before World War II. As third- or fourth-generation Americans, most of the young people no longer speak Japanese. They tend to be good students, but they do not necessarily excel in mathematics, and they do not gauge their self-esteem in those terms. Accordingly, they are not particularly numerous at math competitions, and no U.S. Olympiad team has included a member with a Japanese background. ♦ ♦ ♦ ♦ ♦ and from Beyond the Classroom: Why School Reform Has Failed and What Parents Need to Do by Laurence Steinberg:
♦ ♦ ♦ ♦ ♦ last but not least (here's the cheating part), here's Richard Nisbett, in The Geography of Thought: How Asians and Westerners Think Differently...and Why: The Greek faith in categories had scientific payoffs, immediately as well as later, for their intellectual heirs. Only the Greeks made classifications of the natural world sufficiently rigorous to permit a move from the sorts of folk-biological schemes that other peoples constructed to a single classification system that ultimately could result in theories with real explanatory power. A group of mathematicians associated with Pythagoras is said to have thrown a man overboard because it was discovered that he had revealed the scandal of irrational numbers, such as the square root of 2, which just goes on and on without a predictable pattern: 1.4142135 ..... [yup, that bugs me, too] Whether this story is apocryphal or not, it is certainly the case that most Greek mathematicians did not regard irrational numbers as real numbers at all. The Greeks lived in a world of discrete particles and the continuous and unending nature of irrational numbers was so implausible that mathematicians could not take them seriously. On the other hand, the Greeks were probably pleased by how it was they came to know that the square root of 2 is irrational, namely via a proof from contradiction.... The Greeks were focused on, you might even say obsessed by, the concept of contradiction. If one proposition was seen to be in a contradictory relation with another, then one of the propositions had to be rejected. The principle of noncontradiction lies at the base of propositional logic. ....The basic rules of logic, including syllogisms, were worked out by Aristotle. He is said to have invented logic because he was annoyed at hearing bad arguments in the political assembly and in the agora! Notice that logical analysis is a kind of continuation of the Greek tendency to decontextualize. Logic is applied by stripping away the meaning of statements and leaving only their formal structure intact. This makes it easier to see whether an argument is valid or not. Of course as modern East ASians are fond of pointing out, that sort of decontextualization is not without its dangers. Like the ancient Chinese, they strive to be reasonable, not rational. Chinese philosopher Mo-tzu made serious strides in the direction of logical thought in the fifth century B.C., but he never formalized his system and logic died an early death in China. Except for that brief interlude, the Chinese lacked not only logic, but even a principle of contradiction. India did have a strong logical tradition, but the Chinese translations of Indian texts were full of errors and misunderstandings. Although the Chinese made substantial advances in algebra and arithmetic, they made little progress in geometry because proofs rely on formal logic, especially the notion of contradiction. (Algebra did not become deductive until Descartes. Our educational system retains the memory trace of their separation by teaching algebra and geometry as separate subjects.) The Greeks were deeply concerned with foundational arguments in mathematics. Other peoples had recipes; only the Greeks had derivations. On the other hand, Greek logic and foundational concern may have presented as many obstacles as opportunities. The Greeks never developed the concept of zero, which is required both for algebra and for an Arabic-style place number system. Zero was considered by the Greeks, but rejected on the grounds that it represented a contradiction. Zero equals nonbeing and nonbeing cannot be! An understanding of zero, as well as of infinity and infinitesimals, ultimately had to be imported from the East. ♦ ♦ ♦ ♦ ♦ misdirectionOK, I changed the subject with that last one. But I could have done that even without being ruthless, because I think the history of mathematics is important to a discussion of whether Asians Are Smarter. As I understand the history of mathematics, Asians did not make (many) major contributions. Mathematics is largely a creation of Western Europeans and Indians. On those grounds alone, I would be highly reluctant to give credence to any argument that Asians possess an innate, inborn IQ-advantage in the subject of mathematics. (Do they have higher 'g' overall? They might. For the moment, it's a question of choosing whom to believe, and I'm choosing Stevenson & Stigler, who actually went to Asian countries and tested Asian children's IQ directly. As well, I've mentioned that we know Jim Stigler&mdahs;we know him well enough to trust him. That's not a reason for anyone else to choose Stevenson & Stigler over the VDARE folks, but it's my reason, and I'm sticking to it.)RUSSIAN MATH versus SINGAPOREOn the subject of Asian superiority in math achievement, Nisbett also has this to say:I am sometimes accused of a contradiction myself. Why do nonlogical Asians tend to do so much better in math and science than Americans? How can this be if East Asians have trouble with logic? There are several answers to this question. First, it should be noted that we don't actually find East Asians to have trouble with formal logic, we just find them to be less likely to use it in everyday situations where experience or desire conflicts with it. Second, Eastern lack of concern about contradiction and emphasis on the Middle Way undoubtedly does result in logical errors, but Western contradiction phobia can also produce logical errors. The Eastern reputation for math skills is really quite recent. Traditional Chinese and Japanese culture emphasized literature, the arts, and music as the proper pursuits of the educated person. In research with young and elderly Chinese and Americans, we and others find that only the Comparably schooled older Chinese and Americans perform similarly in math. Asian math education is better and Asian students work harder. Teacher training in the East continues throughout the teacher's career; teachers have to spend much less time teaching than their American counterparts; and the techniques in common use are superior to those found in America. (Asian math-education superioity to Europe in these respects is less marked.) Both in America and in Asia, children of East Asian background work much harder on math and science than European Americans. The difference in how hard children work at math is likely due at least in part to the greater Western tendency to believe that behavior is the result of fixed traits. Americans are inclined to believe that skills are qualities you do or don't have, so there's not much point in trying to make a silk purse out of a sow's ear. Asians tend to believe that everyone, under the right circumstances and with enough hard work, can learn to do math. In short, Asian superiority in math and science is paradoxical, but scarcely contradictory! I've mentioned many times that I've worked through every problem, and studied every page, of Mathematics 6 by Enn R. Nurk and Aksel E. Telgmaa. That experience changed my perception of Singapore Math. Carolyn says "Russian mathematicians have chops." You see that right away, working through RUSSIAN MATH. The book is bloody brilliant. Studying RUSSIAN MATH, I saw the little SINGAPORE MATH 'student helpers' as an earnest, hard-working lot. Not naturally gifted, but willing, always, to put in the time. RUSSIAN MATH is the real deal, SINGAPORE MATH the overachiever. I like overachievers; I hope to be one myself when it comes to math. But an overachiever is different from an Enn Nurk or an Aksel Telgmaa. it's the culture, stupid Part 2Basically, I'd have to see a great deal more solid data before I'd believe that Singapore kids, or Japanese kids, or Chinese kids, or any other kids are naturally better equipped to learn math than any other kids. And now that I've read Steinberg, I'm looking at the culture even more than the schools. That's the bad news.comments... RingsideFest 05 Nov 2005 - 12:46 CatherineJohnson So today we are off to the Ringside Fest, where Christopher will be getting an autographed-something from Carlito & Christian will be getting an autographed-something from Bret Hart ![]() and I will be getting an autographed-something from Jerry Lawler
But first we're going to KUMON.
Then Ringside Fest.
Back later.
updateCarolyn says the little KUMON face is a thoughtful face.update updateThe reason I will be getting an autographed-something from Jerry Lawler is that an autographed-something from Jerry Lawler costs $10, as compared to at least $25 for an autographed-something from anyone else. Also because I don't know who Bret Hart is, and Carlito, while cute & possessing a catchy theme song, has a fat bottom. Not only does Carlito have a fat bottom, his trademark is spitting apples in his opponents' faces. I'm not paying $25 for an autographed-something from a fat-bottomed apple-spitter. Jerry Lawler, I learned this week, is the WWE announcer. By this time tomorrow I will be a middle-aged Math Blogger who owns an official Jerry Lawler autographed-something.JBL isn't going to be there. In case you were wondering.
comments... TeachingGapPart1 06 Nov 2005 - 04:04 CarolynJohnston I'm reading Stigler and Hiebert's book, The Teaching Gap, which we've talked about before (but I finally found it available at my local used bookstore). The book is subtitled "Best ideas from the world's teachers on improving education in the classroom". It's an outgrowth of the TIMSS video study, in which many videos were taken of mathematics teachers at work in American, German, and Japanese 8th-grade classrooms. Here's a telling passage from the book. The rest of the book appears to flesh out the summary this gentleman gave after watching the videos. One of the participants, a professor of mathematics education, had been relatively silent throughout the day. We asked him if he had any observations he'd like to share. "Actually", he said, "I believe I can summarize the main differences among the teaching styles of the three countries." Everyone perked up at this, and this is what he had to say: "In the Japanese lessons, there is the mathematics on the one hand, and the students on the other. The students engage with the mathematics, and the teacher mediates the relationship between the two. In Germany, there is the mathematics as well, but the teacher owns the mathematics and parcels it out at he sees fit, giving facts and explanations at just the right time. In U.S. lessons, there are the students and there is the teacher. I have trouble finding the mathematics: I just see the relationship between the students and teacher."Is that a cool observation? But how condemning of American teaching, if the observation about the American math lessons is true. I don't know about that yet. So far, I've read a description of a German teacher giving a lecture on a proof of Thales' law, and a Japanese math teacher giving a class on geometry. I can definitely see why the professor made the observation he did about German and Japanese teaching. (Digression: I remember being driven nuts by some of my German math professors in grad school. They lectured, and that was all they did; you didn't interact, because you couldn't get a word in edgewise. And they all, to a man, had a habit of going at least 15 minutes past the scheduled end of the class. That said, one of my favorite teachers was my undergraduate linear algebra teacher, who was very German. That was a while ago; for some reason, I can't remember why I liked him so much anymore). The TIMSS video studies have been used as "evidence" that Japanese teaching, clearly more successful than our own, is "constructivist" in the sense that kids are expected to discover their own methods. I posted about it before, here, after reading this article, which offers a different interpretation of the situation in one of the Japanese math videos. I've seen nothing in the description given in The Teaching Gap of the video of one Japanese math class to indicate that kids are really being left on their own to construct their own methods. There are clearly some favored elements of the American constructivist classroom present, the most salient being the occasional short bursts of group work; these are unsurprising, since Japan has a culture that emphasizes group achievement over individual achievement. But, in the words of that perspicacious math ed professor, the Japanese teacher is MEDIATING the relationship between the students and the math. He is not leaving them alone together! The period is over, and Mr. Yoshida interrupts to say, "I know this is bothersome, but I want to know the present situation." He then asks how many students have solved each problem. He concludes the lesson by observing, "There are a lot of people who are using triangles. That's okay, but there are three types of auxiliary lines. Sometimes there are easier methods of solving these problems using other types of auxiliary lines. We will check these in the next period."More to come. I can't wait to get to the descriptions of the American math lessons. Will they be as cringeworthy as the professor's summary suggests?
comments... KumonInWestchester 06 Nov 2005 - 18:50 CatherineJohnson That's what KUMON costs in Westchester County. For that you get 150 worksheets a month, plus 4 visits to the center. You can't even get a haircut for $85 a month here. Best deal in town. 4th grade graduationLast week the KUMON guy told me he was accelerating my pace, because I am 'very strong.' I will treasure those words forever. So I do my last set of 4th grade worksheets this week, then start 5th grade next week. Let me tell you something. A timed work sheet filled with huge long division problems is not easy.updateTimed fraction sheets are way easier. I got my first 100% since starting KUMON. Although having to express a fraction like 77/18 as a mixed number under time pressure and with basically no room for 'side calculations' is a challenge. I did side calculations anyway. Wonder if I'll get dinged for those.JUMP's fractions programSamantha pointed me to the JUMP program, which I had never heard of. It sounds fascinating. I'm going to order JUMP's 6th grade workbook, as well as The Myth of Ability: Nurturing Mathematical Talent in Every Child by John Mighton, founder of JUMP. I bring this up here, because he begins remediation with fractions. That's where he starts. With fractions.it has proven to be an extremely effective tool for convincing even the most challenged student that they can do well in mathematics. [snip] The various steps you will follow in teaching the material in this unit are outlined in great detail below, and also on the Fractions worksheets themselves. The individual steps are never more difficult than “count on your fingers” or “copy this symbol from here to here,” so the steps themselves will never be a barrier to weaker students. If you follow the instructions in this manual very closely, even your weakest students should achieve a mark of 80% or higher on the final diagnostic test (included at the end of the manual). I haven't read through his material closely yet, but it seems that the reason he chose fractions as his jumping off point is that you can manipulative fractions using extremely friendly numbers. Which is true!
comments... KumonIsASupplementalProgramOnly 06 Nov 2005 - 20:23 CatherineJohnson Ken raised a question I'd been meaning to bring up: can KUMON be used as a primary curriculum? KUMON says no, and I agree. The KUMON worksheets are designed to be supplemental. There's no 'KUMON instructor,' even though everything you read talks about the 'KUMON instructor'; there's just you, your worksheets, and your mother, who grades the worksheets. What KUMON gives you is a highly structured, well-thought-out set of 200 worksheets per grade level—worksheets that have been used and revised over 40 years' time. One of the interesting aspects of working through the KUMON sheets as an adult is that they give you practice in things you didn't know you needed practice in until you started doing the worksheets. They're diagnostic, in a way. instructional practiceAs people here point out all the time, at least when it comes to math, 'practice,' 'learning,' and 'conceptal understanding' are not three separate things. I'd call the KUMON sheets instructional practice. The problems usually aren't randomly generated, which is probably one reason why they don't randomly-generate a new set of problems for a student who didn't do well on the first set. (I should add that KUMON, like DI, is designed to ensure that students do do welll on each set.) Instead, a KUMON worksheet often gives you a structured sequence of problems designed to illustrate a principle. As an example, a long division with remainder sheet might have the student work this series of problems: 25/1226/12 27/12 28/12 29/12 30/12 31/12 32/12 33/12 34/12 35/12 36/12 Doing each one of these problems in sequence is going to give a 4th grader a sense of what a remainder actually is. updateChristopher did Sheets C36-C40 yesterday: Multiplication up to 7. The first sheet lists all of the times-7 facts in a table. 7 x 1 = 7 Seven ones are seven.7 x 2 = 14 Seven twos are fourteen. 7 x 3 = 21 Seven threes are twenty-on |
