Hi Julie: Establishing a fair and accurate grading system takes some thought and consideration. It's true, more weight should be given to more difficult assignments. In some ways, it's a balancing act because not all students learn or test well in the same way. So, I try to plan for fairness, and a collection of grading criteria that, in the end, truely measures student learning, in a way that can be justified and objective. I want students to earn the grade they've earned, but just as import, regardless of thye grade, my focus is on the instructional strategies and learning that occurs, with measuring that as a secondary (but important and necessary) second.
