Based on the premise that educational psychology is often taught as theory with few opportunities for practical application, the Student Mini-Learning Exercise (SMiLE) Cards are presented to help students apply educational psychology concepts to field experiences. Components of these SMiLE Cards focus on: identification information; the concept under investigation; definition of the concept; the procedure designed to demonstrate the concept; and reaction following implementation of the procedure. Use of the SMiLE Cards is described as a procedure requiring students to: (1) design, implement, and react to 24 SMiLE Cards in one semester; (2) develop skills in turning theory into practice; and (3) obtain comments and evaluations from the instructor. Suggestions as to how this practice enhances learning retention are offered. (Author/KMF)
