More hybrid students posted response when compared to my regular MAT120 section. Overall, not many responded inspite of me making several announcements in class and sending email reminders. Some students emailed me their answers.
Lessons learned -
I felt that I need to know more about googlegroups before using it. Maybe, I need to find something else that is more appropriate for statistics.
Not to spend more time F2F discussing questions posted on the groups.
Try to post questions that will naturally build discussion among students. I still don't know how to make everyone post their response.
