Designed to provide information about what 46 innovative schools (K-12) have done in individualizing instruction, this manual for school administrators, using examples from the 46 schools, opens with a chapter on how individualized instruction differs from traditional instruction. Successive chapters, also using the schools as evidence, focus on the objectives of individualized instruction, diagnostic procedures, instructional procedures, evaluation procedures, student progress reporting procedures, evidence on effects of individualized instruction, problems encountered, and recommendations on implementation procedures. The manual includes a 57-item bibliography, and is appended with a listing of the 46 case studies (which are available from the ERIC Clearinghouse on Educational Media and Technology, Cypress Hall, Stanford University, Stanford, California 94305), materials used in individualizing instruction, and reporting forms.
