This module on using available media resources to enrich instruction is the third of 11 modules in the set, Introduction to Teaching Adults. Designed to meet the learning needs of part-time continuing education instructors, these modules can be used as resource materials for local workshops or study-discussion groups, as self-instruction (each module takes approximately two hours), and as a correspondence course. (Source information on correspondence study is cited in module 1.) All modules except the first are designed to be used in part in conjunction with an audiotape. The objective of the module is for educators to be able to prepare a plan for using media in the classroom. Topics covered include nature of instructional media, properties common to all media, when to use media, and description of 12 basic types of media, including advantages, limitations, and estimated cost. A six-step procedure for planning and using media is presented. A list of sources of media and annotated listing of books helpful in developing skill in producing instructional materials are provided. (YLB)
