Carmen,
I feel a little different with regards to EC. IIf it's a required topic or material, I expect students to learn it, and their grade will reflect to what degree they did learn. Smoothing over poorer work, missed or failed assignments by giving EC only helps inflate grades artificailly, and does little to contribute to learning. I choose not to offer EC. But each instructor and institution has to decide what works best for them and their students.
