Students' grades reflect performance against learning targets, climbing toward proficiency, then mastery.
Teachers gradebooks and report cards should convey how students are doing in reaching standards.
The grades that students receive will represent how much they have learned, how they have learned, and how close they are to mastery. They don't reflect effort, compliance, or punishment.
Without formative feedback in a recursive learning loop, all students will not move toward mastery. It is the foundation of growth, progress and new learning.
Using zeroes or other punitive consequences to motivate students to do their work well and on time does not lead to more learning or responsibility.
