I thought I'd share what I've done to prepare students for inclass activities.  When I started 6 years ago, a colleague was struggling with poor course evals because she adopted a teaching strategy that required students to acquire the content on their own outside of class.  So, when I decided to adopt the TBL strategy, I knew I would have to provide more guidance to the approximately 60 graduate nursing students in my GYN course.  Our School purchased Articulate PresenterTM which I used to record all of my lectures into shorter (10-15 slide) modules which I post to Bb.  The students then review them along with the reading assignments prior to class. Of course, feedback on course evals still occasionally includes "too much time needed to review the modules", but more frequently the feedback is along the lines of appreciating the opportunity to review the modules at their own pace (sometimes multiple times) and not having to listen to 3 hours of lecture.   Although somewhat time intensive the first semester, the Articulate program is easy to use, and now I just have to update selected modules each year.  I hope this is helpful.
