Hi Jennie: Yeah, usually evening classes - especially 4-hour ones - can be particularly challenging for all involved. Although a bit time consuming, an activity that has worked for me is breaking your class into sub-groups, each with a task. The task could be to discuss one aspect of a lesson or topic. Then, all the groups reconvene to present to the whole class. This also allows for the facilitator/instructor to add essential points that may have been missed, or emphasize key points you want included. Regards, Barry
