The document discusses elements of effective teaching. Effective teaching involves active learning where students learn by doing activities rather than just listening. It also involves disequilibration, where lessons challenge students' current understanding and help them construct new knowledge. Collaborative grouping and providing data for analysis, problem solving and problem finding are recommended approaches. Lessons should also be connected to students' prior knowledge and experiences through contextual learning and authentic assessment.
