Movement in learning or movement-based instruction is a teaching method based on the concept that humans learn better through movement. This teaching method can be applied to students, who should have the opportunity throughout a class period to move around to take "brain breaks" to refocus their attention so they can learn new material. Brain research suggests that physical activity prior to class (in PE for example) and during class, increases students' ability to process and retain new material. This is a new and controversial development in education, and, to date, has little research and empirical data to support this trend. However, anecdotal evidence regarding the benefits of incorporating movement in the classroom is promising.
