I use this form for students to keep track of the objectives for the day. At the end of class they are required to write something that they learned or maybe something that they already knew that we went into more depth about. They are also required to state something that they want more information about or would clarify something that we talked about. This is a simple way to quickly assess the lesson. I use this along side our student planners and agendas. This is sometimes my ticket out the door.
