I have learned two very important things about assessments, this quarter:
ONE) You must be sure to check for understanding both before and after the lesson, or you don't really know if anything has changed or not, and
TWO) If you formulate either question in such a way that it can be googled, you will get something that was very obviously not created by the student, and was just shamelessly copy pasted, at least a third of the time.
