Massed Practice

Massed practice is comprised of training or learning sessions that are long and intense as opposed to distributed practice which uses shorter and less intense sessions to impart information to a student or trainee. Massed practice has been shown through research to be ultimately less successful than the distributed practice model.

As an example, it is ultimately more successful in college classwork to stay on top of a subject by frequent reviews of material rather than relying on all-night "cramming" the night before an exam.
