1) The document discusses Mayer's principles of multimedia learning and their implications for an ESP computing course. It outlines key cognitive learning theories that emphasize structuring information and relating new concepts to prior knowledge.
2) Some multimedia principles discussed include the multimedia principle of learning better from words and pictures than words alone, and the spatial contiguity principle of learning better when corresponding words and pictures are near each other.
3) As an example, the computing lesson presents course content through illustrations with labeled parts and printed words to align with cognitive and multimedia principles. Feedback is also provided to students.
