This document discusses the capabilities and limitations of television, film, and video as educational tools. It outlines how they can bring models of excellence and real world events into the classroom through broadcasts or recordings. They allow viewers to see events from different angles and make some content understandable to a wide range of ages. However, television and film are one-way mediums that can encourage passivity in viewers. Their small screens also limit the size of content compared to movies. Pre-viewing activities for effective lessons include setting goals, linking to prior lessons, providing context, and pointing out focus areas, while avoiding interruptions during viewing.
