This calculator is based on the Course Workload Estimator developed by the Center for Teaching Excellence at Rice University. Their page has extensive descriptions of their estimate procedure and literature citations for student workload research.
This calculator uses the same format, classifications, and estimates for time for student work, but it adds in classroom hours and creates a formatted table for potential use in a syllabus.
Total expected student semester workload hours from SACS are as follows:
4 credits = 180 hours
3 credits = 135 hours
2 credits = 90 hours
1 credit = 45 hours
