How should students be graded in mathematics:
We use UCSMP, and we follow their percentages they feel should be used for grading.
This is a lot of pressure on the students to perform well on the tests. Which I believe is good, because I feel that students need this to be prepared for when they leave school. I have also inserted projects as tests to help students that may have difficulty with test anxiety. The homework is graded on effort, not correctness. I feel it is important for students to held accountable for their own work. If they are choosing not to check them homework and to not to it, then in the end it will only affect themselves.
I think there could be validity in lowering test percentages to 50 or 60% and make it mandatory to do projects or even a paper to cover the additional 10-20%.
