Teaching Problem
I use MyMathLab to run my classes and I have all this great info on each assignment called an “Item Analysis”. Below is an item analysis for a sample exam in one of my algebra classes. Here’s my question, which are the most urgent problems to cover when I go to give my class the review? I’m not looking for an intuitive listing of the top problems, but a spreadsheet function that I can use to sort the problems. Note, something that makes this problem harder is that the questions aren’t given with the same frequency. (Hint: the most obvious is calculating the percent of time a question is gotten correct, but there are certain problems with that.)

Binary Heads
I found this in Kids Discover while hanging out with my daughter in the childrens section of our library. Pretty cool example of a visual binary operation.
ps. Thanks Brian and Lee for getting me off my butt and posting.

Grading…
Lee emailed me regarding my throwing the papers down the stairs experiment.
Hi Hendree -
I know of several methods for grading papers. One I’m sure you’ve heard of is to throw all papers down the stairs and whichever fall farthest get the higher grades. Another is illustrated by the graphic at http://primepuzzle.com/tc/grade.html
Thanks, Lee!

Math + War
Just happened to run into this on a data mining blog. A very provocative use of mathematics to understand Iraq and it’s connection to other world conflicts.

Graphic Self-reference
Lee just sent in this pic he found on Twitter. It immediately reminded me of this comic I just saw on my XKCD feed.
Thanks, Lee!
