Interactive computer programs, developed at Indiana University's Learning Skills Center, were designed to model effective strategies for reading biology and psychology textbooks. For each subject area, computer programs and textbook passages were used to instruct and model for students how to identify key concepts, compare and contrast concepts, and graphically map relationships among key concepts. One hundred and eighty-four undergraduate students of matched ability from a major university and from a two-year community college were assigned to treatment and control groups to evaluate program effectiveness. Students who used the program significantly outperformed control group students, and learned strategies transferred to new and unmodeled textbook chapters. Data are presented in tabular form. Appendixes include a copy of a paper presented at the 1987 National Reading Conference, "The Effectiveness of Interactive Computer Assisted Modeling in Teaching Study Strategies and Concept Mapping of College Textbook Material" (L. Mikulecky), and extensive excerpts from the students' and instructors' guides for the project. (Author/GL)
