The two teaching units in this document present listening and speaking as dynamic skills and emphasize learning through discovery and induction. "Listening to Understand" encourages the student to participate primarily as a member of a group rather than as an individual. Classroom exercises are listed for teaching students efficient listening, the nature of sound, the effect of environmental contexts on sound, the function of word order, changes in language meaning, the techniques used in propoganda and commercials, and the functions of music. "Speaking to be Understood" encourages the student to participate as an individual and offers more opportunity for inferential learning. Methods of teaching basic communication, language learning and dialect, semantics, voice and speech improvement, and oral literature are presented. (LH)
