Imagine a physics class, where kids are taught scientific method and how to run experiments. Curriculum focuses on making hypotheses, interpreting observations, so on. If the exam is just word problems about using physics formulas, does that test understanding?
In this question, how would a child actually solve it at a computer? They would probably run the code and observe. I feel like we should ask questions that more closely build on students' skills.

We evaluate relative to math. Not much "CS" evaluation. That's not really our goal. But Kathi and I have done a fair bit of CS-ish evaluation at the college level — just not Bootstrap.
.@wcrichton I'm glad you questioned how understanding was measured & hope others will also rethink this approach. Even the "correct" answer, I'd say d) is False not True: the drum & costume changes don't happen at the same time, just start at the same time. Word problems?
