Re: ONLINE TEACHING/LEARNING. Believe in science.
"Online Teaching/Learning" may not be as prudent as many educators and administrators think it is. One recent scientific study indicates statistically significant differences 3.77** (critical value of t-test 1.99) plus the Effect Size (ES) .-0.92 on Midterm Exam (MT), Q2, and Q3, (see below) between regular in-person classes and online. …… online teaching/learning may be nothing more than an academic exercise. Technology can leverage faculty time, but it also can replace human contact. Other considerations for the instructor might be the following: How much time would it take to prepare and to maintain the online supplement material?
