The document discusses principles of using multimedia in course content. It describes the multimedia principle of incorporating both graphics and words rather than just text alone. There are different types of graphics that can be used, such as decorative, representational, organizational, and transformational graphics. The contiguity principle states that any text should be placed near the corresponding graphics. Following these principles leads to active learning as students make connections between graphics and text, which can increase engagement and academic achievement through knowledge construction. Examples are provided of both correctly and incorrectly applying these multimedia principles.
