In lecture/discussion courses requiring outside preparation, 1 hour of credit represents 50 minutes contact time each week in class, and 2 hours of work outside of class. Therefore, a 3-credit lecture course requires 2.5 hours in class per week and approximately 6 hours outside of class. In studio/laboratory courses, 1 hour of credit requires a minimum of 1.5 hours contact hours each week in class and approximately 1.5 hours of work outside of class. Therefore, a 3-credit studio course represents a minimum of 4.5 contact hours in class and approximately 4.5 hours of work outside of class per week. In online courses, 1 hour of credit requires approximately 3 hours of work per week for all activities (i.e., reading, viewing, making, scanning, responding to discussion threads, collaborating, etc.). Therefore, a 3-credit online course requires approximately 9 hours per week to complete the necessary activities.
