BEE 3299: Sustainable Development is an interesting course in the Biological and Environmental Engineering program because it is one of the only courses that is entirely web-based. Since all of the assignments are submitted and graded on Blackboard, the main interaction between students and instructors is through teaching assistant commentary on assignments. In this report I will detail how grading and grading instructions could be improved in future semesters of the course and how feedback should be provided to undergraduate teaching assistants to increase commentary quality.
