This document discusses effective teaching approaches and strategies. It begins by asking if content knowledge is enough for effective teaching. It then outlines several instructional approaches like expository (lecture, mastery learning, direct instruction), hands-on (discovery learning, experiential learning, authentic activities), and interactive/collaborative (cooperative learning, reciprocal teaching). It emphasizes the importance of effective questioning techniques like wait time and discusses grouping students heterogeneously when possible to avoid tracking. Finally, it introduces the QAIT model which focuses on elements teachers can directly control to improve instruction.
