If you are not already familiar with Classroom Assessment, we recommend that you “get your feet wet” by trying out one or two of the simplest Classroom Assessment Techniques in one of your class. By starting with (CATs) that require very little planning or preparation, you risk very little of your own-and your student’-time and energy. In most cases, trying out a simple Classroom Assessment Techniques will required only five to ten minutes of class time and less that an hour of your time out of class. After trying one or two quick assessment, you can decide whether this approach is worth further investments of time and energy.
