Participation by course grade and recommended practices based on model 3. Gender was entered into the linear equation as the mean value (0.39) to simplify the figure. PPT pretest is not shown because its value varies from 96 to 100% across the course grades. The results indicate that there were large differences in participation across the different course grades and that when instructors used all four recommended practices rates on the CBT posttests were similar to participation rates on the PPT posttests across the different courses grades
