This page describes the minute paper, one of a series of Classroom Assessment Techniques (CATs) provided by the Field-tested Learning Assessment Guide (FLAG) website. The CATs of FLAG were constructed as a resource for science, technology, engineering and mathematics (STEM) instructors to emphasize deeper levels of learning and to give instructors valuable feedback during a course. The minute paper is a concise note, taking one minute and written by students, that focuses on a short question presented by the instructor to the class. It provides real-time feedback from a class to find out if students recognized the main points of a class session and also helps the instructor make changes for the next class. This site provides an overview of this assessment instrument including information about how to use minute papers in the classroom. The site is also linked to a set of discipline-specific "tools" that can be downloaded for immediate use, as well as supplementary links and sources to further explore this assessment tool.
