In an effort to provide for a smooth transition from an "open schedule" library media center to scheduled library periods, a series of 13 instructional models were developed for use in Detroit's public schools. The models provide a framework for developing a plan of sequential library instruction which can be adapted to the teaching programs of individual middle schools by their library media specialists. Twelve of the instructional models are presented in the publication; each includes lists of entry and exit skills, a unit plan, a sample daily lesson plan for one of the unit's objectives, and student activity sheets for the daily lesson plan. The 12 models cover: (1) an orientation to middle school libraries and media centers; (2) the card catalog; (3) parts and types of books; (4) the Dewey Decimal Classification system; (5) encyclopedias; (6) reference tools; (7) magazines and newspapers (8) the Reader's Guide to Periodical Literature; (9) research and reporting skills; (10) audiovisual materials and equipment; (11) career planning skills; and (12) interpretation skills. It is recommended that library media skills instruction be integrated into classroom units. An appendix contains a pretest, a posttest, and additional lessons, activities, and games for the various skill areas; a list of 16 supplementary references; and a key for the tests. (Author/ESR)
