Hi Susan:
You've put some thought into your media selections, and that's great. Classes do vary from session to session. So, what worked last time may not be the best media choices this time. So we have to put in the time, planning, and effort too consider "how can I best convey the needed course material to my students".
Our focus is on our students learning rather than our teaching. It's not just a job that we perform mindlessly session after session. It's about student learning, and better teachers really have to work at that to make it happen.
Regards, Barry
