Consider the case in which homework problems are assigned only on material for which a step-by-step solution has been provided at some time in class.  In this case, there is always something in the students’ notes that shows them how to solve the problem.  Thus, performance on the homework problems provides some indication that students are doing their homework.  Combining homework problems assigned this way with frequent testing provides a measure of how hard students are working on their homework.  The results from using this method are analyzed.
