The purpose of this study to develop minicourses in educational media for presentation to inservice teachers through the "week-end college" system at Trenton State College. The minicourses were developed primarily through consultation with experts in the field of educational media and administrators at Trenton State College. In addition to the consultations, an analysis of introductory courses in educational media was made. This analysis involved (1) the division of the introductory course objectives into minicourses, (2) the identification of specific educational media competencies, (3) the activities required of the student for developing the competencies, (4) the teaching strategies to be employed, and (5) the methods of evaluation. Three minicourses were developed through this study, each involving 15 classroom contact hours and one semester hour of course credit: (1) Instructional Materials Production and Utilization; (2) Utilization of Projection Equipment; and (3) Utilization of Recording Equipment. Each minicourse was developed according to the course outline format required by the college for the development of all new courses: course description, specific objectives, outline of course, teaching methods, bibliography, basic requirements, evaluation of course, and new course data sheet. The planned procedures for instructional implementation of the minicourses were determined thorough an analysis, a detailed outline for each minicourse, that divides the course into competency modules with specific objectives, activities, and methods of evaluation was developed. Outlines and competency modules are given for the three minicourses. (DMT)
