Whew! I almost forgot to post the events that happened in class yesterday. We took a pre-test for the school year to see how much students understand various scientific concepts. As a teacher, I don't think it makes much sense to blindly teach subjects without first understanding the students' conceptions (and misconceptions) of the subject. I realize the test was long and many have not yet completed it. However, sacrificing this amount of time to identify student strengths and weaknesses will be gained back multiple times by not wasting time on concepts that students understand.
