The catalog (developed by the Great Lakes Region Special Education Instructional Materials Center) provides information on more than 100 auditory learning materials for use in special education. Described in the first section of the catalog are procedures used to evaluate and classify auditory instructional materials, including a list of classification descriptors, sample forms, and an explanation of a learner classification system. Entries are arranged alphabetically by title and usually include a one-paragraph description and picture of the material, the author's name, the producer's name and address, date, cost, a list of student objectives, and information on content, procedures, and equipment needed. Also included is notation of the curriculum focus area and level of student for which the material is recommended. Entries are indexed by titles, producers, broad interest areas, and recommended interest and/or use levels. Associated with the catalog are a cassette tape and printed publication which present practical suggestions for designing auditory instruction and making auditory instruction meaningful. (LS)
