So another question we asked students was this one…
The times and positions of an object are given in the table below. What’s a good estimate for the speed of the object at the instant t=2?
Here’s what I’m interested in knowing…
If you had to write a multiple-choice version of this question, what options would you give students, and why? In other words, what approach or thinking underlies each choice? Are any of your choices degenerate?– meaning that the answer could point to very different thinking/approaches?
What’s something you would want to ask a student as follow up (either generally or to particular answers)?
