The document discusses the multimedia principle which states that students learn better from words and pictures than from words alone. It explains that humans have separate channels for processing visual and verbal information, and learning is improved when both channels are used together. Graphics can support different content types, like representational graphics for facts and process graphics for procedures. The contiguity principles hold that corresponding words and graphics should be placed near each other spatially and synchronized temporally for best learning. Examples of violations and proper uses are provided.
