Hi Gregory:
Boy, I agree. EC to raise grades focuses on points and grades, not learning or improved performance. If students can't get the essential material, I don't think they should be rewarded with points from another activity that wasn't assigned. Many teachers disagree with this practice - these are my sentiments. In fact, this whole category of EC is very controversial. So I usually try to stay claer of expressing too much my persoanl biases.
