Near the end of the course, it seems much has changed (Table 1 and Figure 2). By week 13, participants rate themselves as working harder on projects, readings, and discussions, and doing more collaboration, this change is statistically significant as well as practically significant. Here Cohen’s is used as a measure of practical significance, where = .2 represents small effects, = .5 represents medium effects, and = .8 indicates a large effect. On this measure of practical significance, we see “very large” effects ( ranging 0.93 and 4.04) for the statistically significant changes (Cohen, 1977).
