Lesson 7 - Choosing Media

Although audio can be used on its own, it is often used in combination with other media, particularly text. On its own, it can present:

• Spoken language (including foreign languages) for analysis or practice
• Music, either as a performance or for analysis
• Students with a condensed argument that may
• Reinforce points made elsewhere in the course
• Introduce new points not made elsewhere in the course
• Provide an alternative viewpoint to the perspectives in the rest of the course
• Analyze or critique materials elsewhere in the course
• Summarize or condense the main ideas or major points covered in the course
• Provide new evidence in support of or against the arguments or perspectives covered elsewhere in the course
• Interviews with leading researchers or experts
• Discussion between two or more people to provide various views on a topic
• Primary audio sources, such as bird song, children talking, eye witness accounts, or recorded performances (drama, concerts)
• Analysis of primary audio sources, by playing the source followed by analysis
• ‘Breaking news’ that emphasizes the relevance or application of concepts within the course
• The instructor’s personal spin on a topic related to the course

This technique was later further developed by Salman Khan, but using video to combine voice-over (audio) explanation with visual presentation of mathematical symbols, formulae, and solutions.
