Carmella,
For my health and medical classes, I feel there is certain amount of material and knolwedge that has to be learned. Students who have done poorly with some of the material to the degree that EC would benefit them have probably missed too much essential information. EC could only artifically inflate their grade, and in some cases produce poorly trained, even potentially unsafe workers. For me, I just choose not to award EC. Each has to decide what works best for them and their students.
