Evaluation Overload

Today we required the kids to do 3 forms of evaluations: blogging, video closet, and written evaluation forms. I really feel this is too many. By reqiring a higher quantity, the quality of the responses seems to decline. Also, the kids have become reluctant and a bit resentful when asked to do the evaluations. I believe 2 forms of evaluation per day is the maximum we can require and still maintain both quality responses and positive attitudes. (Of course, this would change with different age groups.)
