Answer each of the following questions based on your reading “Investigating graphical representations of slope and derivative without a physics context” by Christensen.

1. Do you see any commonalities between the way the students in these studies answered the questions and the way your students determine slope and derivative from a graph or the way your students interpret motion graphs?

2. What do you think the value of “physics-less physics questions” is?

3. What would you have wanted the authors to do as part of a follow-up study?
