Sunday at the Movies (Math Miseducation)

May 22, 2011 by .(JavaScript must be enabled to view this email address) at 05:48 AM

This video illustrates one of the fundamental flaws in the way math is being taught in Ontario. Although the video refers to two American textbooks, the main texts used in Ontario (Math Makes Sense and Nelson Math) suffer from the same flaws. This should not come as a surprise, since the Ontario curriculum mandates the same flawed approach. For example, the grade 4 curriculum (p. 67) requires that students “divide two-digit whole numbers by one-digit whole numbers, using a variety of tools (eg., concrete materials, drawings) and student-generated algorithms”.   LINK IF VIDEO WON’T PLAY

Thanks for naming the culprit publisher,very brave of you.I have known this for a long time.

I am convinced there are political relationships with publishers with no regard as to whether or not the curriculum can teach the children.

The corruption runs deep.

If you have not already, after the first video, there is a response stating the opposite from a math college professor. I chuckled a lot, but when he defended the math books in question, that it has the big ideas. Yeah right big ideas without the bother of having clear explicit definitions on the math laws. Big ideas without the bother of providing the why part. I am still wondering why people would defend the fuzzy math techniques and ignore the remediation of math skills, most of it foundation work at the college or university level.

And than there’s my 15 year old, who suffered the years of marks being taken off, even though she had the correct answer, but using the wrong methods. I had to keep telling my youngest, one day you will have your revenge. That day has arrive, and her favourite pastime, is finding an easier way of doing the problems in trig, calculus and algebra, all based on that firm foundation in arithmetic. From time to time, the math teacher copies her technique and not the technique used in the book. The thing that is talk about the most by the teachers, is her ability to make math easy. But she still cannot do fuzzy math, or even make sense of the techniques used, no matter what grade she was in. If she decides to tutor other students, she will be put in charge of students who are not doing so well in math. She will have the leeway to work on the foundation, rather than following the outcomes of the course. I heard that she might send her to the grade school, which does look good on university applications.

the ‘missing link’ is server-related.  i’m running firefox on linux, on my machine there is no link.  i walked to a windows machine and ran the same version of firefox, and it is there.  i examined both HTML pages, only the windows machine was sent the embedded link.  (great video!).

umm, on further investigation, the video doesn’t show up if you go directly to the blog page (eg: http://www.societyforqualityeducation.org/index.php/blog/read/sunday-at-the-movies-math-miseducation/ )

this happens on all machines.  my problem was that i used an rss link to your blog on my linux machine, and typed in your site and clicked on ‘blog’ in the menu on the windows machine.

Very interesting discussions at kitchen table math.

http://kitchentablemath.blogspot.com/2011/05/fuzzy-charters.html
Also see the previous blog entry.

What the comments describe about fuzzy charters echoes my perception about private schools in Toronto. Most of them are fuzzy. They are a bit better, perhaps the expectations are a bit higher but the curriculum is fuzzy and not necessarily better taught.

To assuage parents’ concerns most private schools in Toronto and especially the big names ones only hire certified teachers, therefore people trained - and brainwashed in my opinion - in child-centered, fuzzy teaching methods.

Unless charter schools are allowed and ideally encouraged to use non-certified professionals who can teach and unless we dispel the myth that a person in Ontario who has a teacher certification is most likely a good teacher and a better one than a non-certified person, charter schools will not be on average a lot better than the public schools.

Ontario no longer has a critical mass of competent elementary teachers. And after 20-30-40 years of child-centered, constructivistic teaching, parents have come to expect good results while their child has fun when learning all the time and without their child having to work hard or having to pay attention.

On the previous post of Europe’s link, “Are there any parents anywhere in the country paying out of pocket to provide their children private lessons in Math Trailblazers?”

The same could be true here in Canada. Is there anyone paying a tutor for Math Makes Sense? 

Europe,  if parents just wanted their children to have fun, without the hard work, which does appear to be my own observations, why is there not a bigger roar from that crowd when their children attend first year post-secondary. , I would be a bit angry, if I was forking over dollars to address their academic weaknesses, that should have been taught in the K to 12 system. But than again, perhaps they see me as the fool, since most of them truly think I am wasting my time and effort on a child who has LD. Just the other day, my child received a 96 on a math exam, and the kids whose parents think along that line, dismiss it and said to her you took the SPED test. The teacher overheard that remark, and told them she took the same test as they have, and should be asking her for help the next time, instead of me. As reported to me by my child, but than again she is doing well, since she and others can do other methods besides the fuzzy math techniques.  It is one rule that has been thrown out, and I do think to make allowances for my child, because she really cannot make sense of fuzzy math, and to be honest, I cannot do it either, even back when she was in grade one. I would probably fail the constructionist math tests at any grade, but score big on the bonus questions, that had the whole concept, and not just the bits and pieces of the concept.

So, the Teacher’s Reference Manual for Everyday Math says that it is not worth the time to teach ‘highly efficient paper-and-pencil algorithms’!  The lunatics have taken over the assylum—tax dollars completely wasted again grin
Nancy, I watched this months ago when you had cited it.

In all fairness, the lattice method of multiplication, that the video says is poor is excellent in my opinion.
