In clinicals, we have a pre- and a post-conference, where we talk about what we are going to learn, and then later, what we did learn or do. For the post-conference, I am going to borrow a tradition from a group I used to lead, and that is "one good thing." No matter how scary or frustrating the day has been for the students, I will challenge them to list one good thing about it. It can be some valuable (yet painful) lesson they may have learned, or a kind helping hand just when they needed it, or any number of things. But I think this is a great way to close out a meeting too, and some appreciation for others may be expressed as well, which is always nice.
