This document discusses how to effectively apply the multimedia principle in e-learning. It emphasizes using words and graphics together rather than just words alone to enhance learning. Different types of graphics are described that can be used, such as representative graphics to illustrate concepts, organizational graphics to show relationships between ideas, and transformational graphics to demonstrate changes over time. Examples of using graphics to summarize growth statistics more efficiently than text alone are provided. The summary stresses that choosing the right media for the lesson content is important for deep learning.
