Time on Task
Time on task is the total learning time spent by a student in a college course, including instructional time as well as time spent studying and completing course assignments (e.g., reading, research, writing, individual and group projects.) Regardless of the delivery method or the particular learning activities employed, the amount of learning time in any college course should meet the guideline of the Carnegie unit, a total of 45 hours for one semester credit. In conventional classroom education this breaks down into 15 hours of instruction plus 30 hours of student work/study out of class per credit.
A three credit course would include 45 hours on instruction and 90 hours of outside of class assignments.
