This booklet is the seventh in a series on educational practices that generally improve learning. The psychological principles described in the booklet summarize important findings of recent research on learning that is relevant for education. The principles attempt to integrate research coming from diverse areas of psychology, including educational, developmental, cognitive, social, and clinical psychology. As a whole, the principles are meant to provide a comprehensive framework for the design of curricula and instruction. The discussion of each principle includes a summary of research findings and a description of the implications for teaching that follow from them. The principles are: (1) active involvement; (2) social participation; (3) meaningful activities; (4) relating new information to prior knowledge; (5) being strategic; (6) engaging in self-regulation and being reflective; (7) restructuring prior knowledge; (8) aiming toward understanding rather than memorization; (9) helping students learn to transfer; (10) taking time to practice; (11) developmental and individual differences; and (12) creating motivated learners.
