My students are adults and enjoy active learning in the classroom. I work to involve as much student participation as possible as long as it does not detract from the lesson objectives. One activity I like to use is small groups to solve a problem. With members from a variety of National Agencies, students must collaborate to develop a possible solution to the situation they've been given. I guide them through a number of discussions to help narrow down possible solution sets. At the end of the course, the small groups present their solution to the other three groups. This not only provides the groups the opportunity to apply what they've learned, but also to assess the other possible solutions developed by the other groups. They learn from each other as well as the formal instruction.
