Audio presentations

SO YA' WANNA DO AN AUDIO PRESENTATION? This page briefly describes how to use audio as the primary mode of instruction (as opposed to multimedia in which audio is a component). In particular this page will focus how and when to use Recorded Lectures, Audio Tutorials, Radio and/or Language Laboratories.

General Audio Tips

Don't use audio presentations in place of print materials Avoid long presentations because of attentional fatigue When using recordings, don't repeat since students can rewind as necessary

Audio Presentation Overview Use the chart to select a type of audio presentation and then click on the name to find out how to implement it.
	Recorded Lectures	Audio Tutorials	Radio	Language Laboratories
When to use	Students in the lower quartile Students at-risk of dropping out Information that will need to be recalled	Students are able to work indepen-dently Well-trained instructors not available Critical thinking is part of the learning objectives	Lower achieving students Other media is too expensive Classroom instruction may be inadequate	Foreign languages Access to computers set up in study carrels

Design Strategies
Recorded Lectures	Provide printed notes to go with the recorded lectures Use compressed speech (word rate faster than normal conversation). People can understand faster than normal conversation (150-250 words per minute). Faster speech can indicate expertise and thus inspire confidence. Compress speech by either speaking more rapidly or by using sound editing software (eg. Macromedia's SoundEdit 16)	Compressed Speech Examples Click on Audio Bob to hear examples
Audio Tutorials	Design it as a programmed guide to direct students' attention to materials Use informal, conversational speech Have the students stop the tape periodically. Use an sound effect as a signal. Use a well structured sequence of learning events List activities (hard copy) Assign activities to different kinds of sessions Keep it simple
Radio	Use as a supplement to text Use compressed speech (see Recorded Lectures)
Language Laboratories	Acquire a language software package that allows students to record themselves using instant playback (student response is repeated within .5 sec) for translation Have students practice as often as possible (daily) Use with formal ear-training when teaching a language so students can self-correct	Instant Playback Example
