This book is a hands-on guide for designing and developing computer based materials for education and training. The text is written from an educational instructional design aspect rather than from a programming point of view. Topics covered in the book include: (1) design structures of computer based instruction; (2) performing an analysis of the intended instruction; (3) managing, individualizing, and humanizing computer based instruction; (4) designing program management and instructional frames; (5) designing screen displays; (6) using text and graphics in computer based instruction; and (7) developing program documentation and support materials. Many figures are given, representing both positive and negative instances of program design. (MVL)
