The document discusses four resources - audio, text, video, and visual - that teachers can use in the classroom. For each resource, it should include the advantages and limitations, ways to integrate them by noting grade level, subject, topic, objective and how it will be used. It also should include at least one encoding and decoding student activity for each resource. Resources should follow Mayer's principles of dual coding, reducing extraneous processing, managing essential processing, and fostering generative processing, as well as design principles.
