UbD DI Chapter 8

This whole chapter is about the most effective way to grade in a differentiated classroom. Tomlinson and McTighe talk about how there is no absolutely perfect way to grade in a differentiated setting because it is difficult to grade on knowledge. According to this chapter grades should be solely based on a student’s knowledge of the material and not on the extra factors. I can agree and disagree with this statement. Students should be graded on what they know and not how well they can complete a project. On the other hand, how does one grade what a student knows without some sort of evaluation? I do not understand how to grade my students the best for everyone.
