This instructor's manual discusses the use of three videotapes and three slide sets that were produced for the purpose of triggering, or stimulating, students to say and use particular sounds frequently in conversational speech. The manual provides statements of the purpose and objective of the media, a list of components, student performance objectives, sample questions to stimulate discussion, and a list of adaptations that can be made when the media are used in classes. Also provided are transcripts of the taped material about the "r,""s," and "l" sounds, and word lists for use in discussion. (RH)
