Instructional models are distinct sets of sequenced teaching actions created to promote student achievement of selected learning outcomes. They identify: (1) the type of information to be presented to students; (2) the sequence in which it should be presented; (3) the teaching tactics that stimulate necessary cognitive learning processes; and (4) the tasks students must perform successfully to apply what they have learned. The study of instructional models helps preservice teachers develop a cognitive framework for making teaching decisions. An instructional models approach rests upon two basic assumptions: (1) the classroom situations, content goals, and students differ so widely that no single teaching method will ever be universally effective; and (2) a wide range of instructional options exist, and teachers can adopt and adapt these models to their unique situations. The two families of models most appropriate to social studies teachers are the information processing models and the social interaction models. A models approach in a methods course is a powerful means to help preservice teachers become effective social studies teachers. It provides a cognitive framework for understanding instruction and a basis for responding appropriately to different curriculum goals. A models approach ensures that preservice teachers have the knowledge and technical skills needed to make a significant contribution to the education of citizens. (SM)
