The Problem

Teachers spend 15–30 minutes grading each essay. A class of 30 students = 8–15 hours per assignment. Feedback is inconsistent across students and grading sessions. Rubric application varies subjectively. Students want faster turnaround but teachers can't grade faster. Large university classes get minimal written feedback.
