“Innovation” #2: Used Horizon Wimba for Real-Time,
Archivable, Virtual Office Hours and for Recording Review
Sessions
Intended to address the following issue:
Most students do not come to my office hours, either due
to shyness or laziness, or because their schedules do not
allow it.

If I had access to chemistry animations online
1. I would make them an integral part of my study process because they’re very helpful
2. I would make them a small part of my study process because they’re somewhat helpful
3. I’m not sure if I’ll use them or not4. I probably wouldn’t use them much
because they are not helpful5. I would avoid them like the plague
because they actually hurt instead of help

If I had a choice between a “traditional” chemistry course (such as this one) and a “high-tech” course with 1/4 to 1/2 of the lectures replaced by interactive web assignments
and animations, I would:
1. Definitely sign up for the “high-tech” course
2. Probably sign up for the “high-tech” course
3. Not sure4. Probably stick with the
“traditional” course5. Definitely stick with the
“traditional” course
