Give your students the opportunity to learn BEYOND the test. Give your students the option to do extra work, put in some extra time, and learn more about the topic at hand. To them, they will be bringing up their test grade, but what we as teachers know is that they will also be LEARNING more, which is all we want!
This policy is not meant to give students a way to an "easy A" after they didn't try at the beginning. As the teacher, you still have the autonomy to make decisions on just what the student needs to complete and learn, and just how much they can raise their grade. This policy just provides you with the basis for the process, and a way to introduce the process to students.
Package includes a handout announcing and explaining the process (to hand out to students or administration, a letter to parents to explain the process, and the contract needed for students to begin the process with you).
Check it out, and help your students increase their learning beyond the test!
