I gave an assessment with similar questions to the chapter 1 and 2 exam along with a few other assessment items. It was a little rough. And by "a little" I mean "a lot". I was really concerned about giving students their test scores - even with "re-learning" and "re-assessment" I was concerned that for some of these students, seeing this score would deflate them.
SO... today I gave them back their bubble sheets without any corrections on them. I said they could work with one partner and look over their tests together - discuss the differences, and then come to a conclusion together. Before hand I did a nice little lecture about how this is about LEARNING, not the grade. So it was more important that they asked each other questions to clarify their understanding rather than that they both "put A" as their answer. Students were engaged the full time - they got to practice their collaboration skills, and we got to practice our test-taking skills together.
One thing I keep thinking about is how I am going to do test-prep for students in April/May. We have one practice test from the AP... and... that's it. I know there is a bigger picture than the AP test for this class, but at the same time, I do want my students to do well and I literally don't know how to ensure that happens.
ALSO, for this unit, I used Baker's analogy of plumbing and latency/bandwidth and it helped clarify the difference for students - thanks!
