What does the data say?

I have tabulated the results from a few of the surveys I gave to students.  I asked the question, "How much did you learn during the first trimester?"  The chioces were tons, a lot, some, not much, almost nothing.  Out of the 55 surveyed, 0 students responded with "not much, or almost nothing."  50 out of the 55 said they learned "tons" or "a lot."  I was pretty happy to see this.  I believe the movement had a lot to do with it.  The movement forced students to participate and when one participates, one learns.  Do they have a deep understanding of the material?  That is something I need to investigate further.
