This document discusses evidence related to effective teaching strategies and evaluating teaching quality. It examines evidence that some teaching methods have been found to improve learning when implemented, but that determining the most effective strategies is complex. It also notes that different observers do not always agree on evaluations of teaching quality. The document then presents a general framework for teaching quality with six elements: (1) pedagogical content knowledge, (2) quality of instruction, (3) classroom climate/relationships/expectations, (4) behavior/classroom management, (5) beliefs about teaching and learning, and (6) wider professional elements like reflection and communication.
