Exit Ticket
Exit Tickets are a highly adaptable and easy to implement formative assessment. In most cases, Exit Tickets include just a few questions asked of students before they leave a classroom. Their answers can be written on a sheet of paper or index card or submitted electronically via email or an online survey.
Marzano (2012) suggests that there are four approaches faculty can use on what he calls "exit slips", each offering its own kind of insight into student learning. For exit slips that focus on formative assessment, he offers the following language, noting that student responses will likely be shorter than the prompt itself:
"How would you rate your current level of understanding of what we did today? Score yourself a 3 if you understand everything we did and can even think of ways to use this learning. Score yourself a 2 if you understand everything we did but can't think of how you would use this information right now. Score yourself a 1 if you understand some of what we did today but are confused about some important parts. Put a 0 if you understand very little of what we did today or are completely lost."
