We also asked students how many hours per week they
spent outside of class working on the statistics class. Hybridformat
students report spending 0.3 hours more each week,
on average, than traditional-format students. This difference
implies that in a course where a traditional section
meets for three hours each week and a hybrid section meets
for one hour, the average hybrid-format student would
spend 1.7 fewer hours each week in total time devoted to
the course, a difference of about 25 percent. This result is
consistent with nonexperimental evidence that ILO-type
formats can achieve the same learning outcomes as traditional-
format instruction in less time, which has potentially
important implications for scheduling and the rate
of course completion.
