My regular Wednesday evening class is for working adults who are developing their language and professional skills. We do a lot of task-related work with particular focus on presentation skills. We role-play activities designed to use and develop the students' real life knowledge, with an emphasis on student input - I try and keep my mouth shut as much as possible, working more as a facilitator than a trainer. 

They're a good crowd, and bring a lot of different perspectives and experiences to the activities. These classes are rewarding for me because I can usually learn something from someone, and build on the students' knowledge. This helps them a lot more than simple language-learning would do.
