Individualized instruction is an old concept that has been newly mandated by the Education for All Handicapped Children Act of 1975. Although neither widely used nor well-defined, individualized instruction is particularly relevant for students who fall outside the norms, behaviorally or academically. It has particular value for ghetto students and delinquent male adolescents. Research indicates that gifted students also benefit from an individualized approach. In most individualized programs, students work at their own paces and pursue objectives based on their unique learning needs. Teachers employ a variety of teaching strategies geared to students' aptitudes and frequently evaluate student progress. Effective leadership from the principal, staff commitment, and upper-level administrative support are identified as keys to success in individualization. Teachers tend to become more effective with individualization over time. Decentralized management and a centralized curriculum also contribute to a successful program. (Author/WD)
