Hi Jodi, The mini-lecture format is based upon the flow of the material. The ideas is to present a concept along with supporting information and then pause with an activity to reinforce what has been learned. This could be a small group activity, Q&A session, or any other form of change of pace. Then you can go into your next section. The human brain needs a change of pace to stay engaged and by changing the flow every 15-20 minutes you are helping the students to reset their brains. You don't have to take a break or disrupt the class with these mini-lecture breaks. Keep on topic just change the presentation format to keep their interest. Gary
