The strategy for grading homework that was in the lesson was not very helpful to me. I teach a hand drafting class. Each week the students turn in a drawn assignment. There are three areas that I access: Lettering, linework and layout. Each gets 33 points, with the extra point being for exceptional work. I red line each drawing, pointing out what was done incorrectly and where improvement can be made as well as pointing out what was done correctly and where improvement has been made. This takes a tremendous amount of time. Is there a better way to do this?
