Elementary Math Grows Exponentially Tougher

i ended up finishing up my masters at home, but not by choice.
i was on long term bed rest and was not allowed by my dr to
drive halfway across the state of michigan to class 2-3 times
a week. i guess i pioneered my own online degree.

Math Grows Exponentially Tougher

It seems to be a good thing. But than again, it might lead to falling behind of more students and a few crystallize as passing.
And there will be fewer and fewer good jobs around, the elimination of the unqualified is beginning early.

We were taught some of the “alternative algorithms” after we’d already memorized the basic multiplication tables and the standard method of solving problems, as ways of estimating the answer quickly in our heads, but I can’t see that they’d be very effective as primary methods of teaching, particularly for students who haven’t learned their math facts and/or when taught by people who don’t understand math very well to begin with.

I think you’ve hit the nail on the head.

or queue theory ...

Some of them might learn to do some of those "jobs Americans won't do"...

You may be interested to know that many schools have open internet courses that can be downloaded and taken for free.

Chemistry as well as many mathematics courses are on the list.

Why thank you! I had no idea!

It is “crazy hard” because it is deliberately mystified. The textbooks only give part of the information so that the teacher is required to provide the rest. Many teachers do not understand it, themselves, having been “educated” with the same sort of texts, and so their own teaching is botched and math is reserved to the brighter self-motivated kids who can piece it together from the hints in the books.

[arthurus]

unfortunately, it requires addition and subtraction

No addition beyond simple counting. I used to go to the parish hall after mass every Sunday for coffee and doughnuts and saw the kids selling the doughnuts having trouble making change because there was no machine. One by one I taught 50 or more kids how to make change. For many it was a revelation that math was just regular mechanical computation and counting rather than some social study that had something to do with self esteem. Some asked why they were never taught change-making in elementary school. It never took more than a few minutes to teach it to even a not-too-bright kid and gave the slow ones a big dose of self-confidence, especially knowing they could do something that their brighter classmates couldn't do.

You are welcome, BTW, I loved teaching chemistry, Kids love to do things with their hands besides take lecture notes and do worksheets. Chem, (and the other sciences and even math to some extent) should be livened up with lab exercises. I tried to do at least one a week.

[brytlea]

I always envisioned doing a lab once per week, (when I taught biology) but it was difficult to work them in that often. The kids we had couldn’t cover the material very fast and we had to get from A to Z before the end of the semester. We did DO labs, but I agree, much more time should be spent on labs and other hands on activities.
