Teaching strategies are generalized plans for lessons that include structure, goals for learner behavior, and tactics. Significant strategies include expository, interactive, small group, inquiry, and individualized teaching. Strategies vary based on students' needs, applicability of methods, and no single superior method. Instructional strategies are categorized as teacher-controlled, learner-controlled, or group-controlled. Teaching methods define how content is presented, such as telling (lecture, discussion), showing (demonstration), or doing (projects, role-playing). Selection of teaching strategies should consider objectives, learners, resources, and constraints.
