@baker Thanks for the explanation.
@dougmmcnally @krthibodeaux Thanks for the inspiration!
I expect my students would react poorly to the assessment built into Code Studio. Most of them have no idea what an AP exam is and have never taken an AP class before. Some of them think of themselves as poor test takers (our school is exempt from NYS standardized tests) and as a class they're just getting the hang of the "Concept Invention" and "Group Problem Solving" lesson style.
I don't want to give them the impression that having open-ended lessons means they'll be poorly equipped for the exam. I think I will create my own assessment with a mix of straightforward review questions and unfamiliar questions to push their thinking.
As they gain confidence, I will push them more and more outside of their comfort zone when it comes to assessments.
