It appeared that students learned more quickly in
the distance learning, in a course of fixed length for
three weeks, where there was much time to
retraining and retesting students,There was equal
effectiveness between groups at the end . This
analysis supports many reports that did before a
period of time which distance learning group
performed as well, if not better than, a resident
control group.

“Compared the results between online group and
normal group in classroom. The online group
typically achieved the highest GPA mean in each
topic, and the highest cumulative GPA Average
mean. The SD and Variance for this group indicate
a consistent high quality learning of content. The
online group is the most successful at cognitive
learning as measured by the end of course
examinations."
