An inservice workshop program for elementary school teachers in Israel helps them in coping with students of diverse ethnic and economic backgrounds. Program topics include discussion of: individual differences, pluralistic views of education, tests and measurement methodology, and new instructional strategies. Emphasis is placed on values clarification so that participants can develop more objective perceptions, reduce hostile feelings, and encourage an acceptance of heterogeneity. The program also focuses on planning for core and peripheral curriculum, teaching and learning for mastery, teaching and learning by way of a variety of alternative methods, and measurement and evaluation of achievements. The most salient components of the program, as perceived by the teachers, are: (1) the concept of heterogeneity; (2) teaching slow learners; (3) matching time and pacing to individuals; and (4) core and peripheral curriculum.
