It is important that instructional materials in a school library/media center contribute to students' learning. A series of experimental units of course work was prepared for high school students by a school library/media specialist. Contents were preselected to enable students to fulfill cited objectives but sufficiently open-ended so that interests or questions raised by the contents could be pursued. Media used included stereotapes, 8mm films, filmstrips, books, essays, recordings, cassettes, videotapes, and combinations of these. The program was based upon the relationship between directed learning and learning itself, while downplaying free selection unguided by specific objective. (SK)
