- What was the student thinking? How did he or she decide to make these particular marks on the paper?
- What question or problem would you pose next to help the student make the next step toward understanding?

Maybe for this one, we should focus on question 2. What questions or problems would help the student move toward a better understanding? What would help him/her reason herself out of this mistake the next time an opportunity for it temptingly appears?

P.S. I’m looking for more authors for this blog. If you would like to share student work here, please email me at physicsmistakes at gmail dot com so that I can get you set up as one of the blog authors.

Keep calm and mistake on!
