Sharing assessment & grading strategies that help students learn
First, a disclaimer: I am not and never have been a Math teacher. After teaching Modern World History for 7 years, I went to the "Dark Side" and became an administrator, so I probably don't know anything about teaching Math.
However, I do know a few things about teaching in general. Furthermore, I have a pretty good grasp of the philosophy of AFL and how applying it in the classroom can increase student learning. So I'm going to give this a shot.
