Would the student have made this mistake if she were just given to evaluate? If yes, then what’s the misconception. If no, then what’s going on? Oh, and go check out Chris Robinson’s stuff, and go follow him on twitter.

I agree, it is odd that 8^3 seemed to pose no problem but 5^2 did. It is probably due to attention, but might be a “visualisation” misconception: when visualising “five squared” we see “two fives” which are “ten”? Or perhaps I’m looking just a little too hard 🙂 I agree with absolutevalueofteaching that this is a lack of attention to precision. When the student got to 5^3, s/he had to pay attention because s/he could see the + and the a x b coming up ahead down the road. Comments are closed.
