This document discusses various models of teaching and influences on teaching. It begins by outlining Bruce Joyce and Marsha Weil's model which categorizes teaching models into four "families": information processing, social interaction, personal growth, and behavioral systems. Each family contains several specific teaching models. The document then discusses the influences on teaching, including changes in society, technology, and recognition that different types of learning require different teaching approaches. It outlines three perspectives on the impact and probabilistic nature of different teaching methods.
