I know that this discussion has happened before but once again it is that time of the summer that I reassess my grading policy and homework stares me in the face. I have thought about several scenarios all summer and cannot think of one that will help me reached my goal of having students do the homework in order to better understand the material and to practice working with the newly introduced concepts. Before teaching AP Stats, my less motivated students did not care enough to copy, but my AP students are highly focused on grades. First year, I gave credit for trying and corrected selected problems, second year I graded most problems and grade reflected correctness. Both years many students just copied from their peers. A group of my Chinese students even wanted to argue that homework is a waste of time and in China the teachers do not care whether students copy so why should I. So is there a solution. Don't give credit for homework and only those students who are highly motivated and understand the connection between homework and understanding will do it? Make it worth such a small amount that students don't feel the pressure to copy? Still in a quandary going into my third year of AP Stats.
