Robert Marzano, classroom researcher and education author, recently wrote in depth about this formative assessment. In the article, he shares four uses for exit slips. He states that students can (1) rate their current understanding of new learning; (2) analyze and reflect on their efforts around the learning; (3) provide feedback to teachers on an instructional strategy; and (4) provide feedback about the materials and teaching. An exit slip can also be be a great way to set up the next day's learning. An exit slip might also be used to sum up the week's learning. Students write what has "stuck" with them this week! Exit tickets have many, many productive uses as "snapshot" assessments with students to gauge learning and instruction.
