Experienced teachers may learn from this manual how to author individualized learning packages. Based on the sequential steps for producing learning materials, a variety of activities for diagnostic, instructional, and evaluative purposes are included in it. The manual is organized into four major parts: (1) "A Model for Individualizing Instruction," which presents a description of individualized instruction and an overview of instructional technology and the training course; (2) "Designing an Individualized Learning Module," which describes each successive step involved in planning and structuring the basic framework for a module and which provides the learning activities necessary for the accomplishment of each step; (3) "Developing an Individualized Learning Module," which includes a description of the techniques required to write and revise a self-instructional package and provides learning activities for the acquisition of any necessary skills; and (4) "Analysis and Assessment of Effectiveness," which provides a description of the procedures for insuring the module effectively teaches what it is designed to teach and for comparing the module with other instructional techniques and/or media. A selected bibliography is appended. (Author/MF)
