As one of the components of the Project ACTIVE (All Children Totally Involved Exercising) Teacher Training Model Kit, the manual is designed to enable the educator to organize, conduct, and evaluate individualized-personalized physical education programs for children (aged 6 to 18 years) with low physical vitality (including those with mental retardation and learning disabilities). An introductory chapter covers definitions and student and teacher behavioral objectives. Chapter II explains procedures for diagnosing the physical fitness needs of children. A systematic procedure for assessing student progress effectively is described in Chapter III. Chapter IV shows the interrelationship between the diagnostic and prescriptive processes. Chapter V focuses on the evaluation of student progress at the end of a specific block of time so that a decision can be made regarding subsequent programing. A final chapter outlines tasks and activities which provide a cluster of learning experiences that will enhance those factors listed in the physical fitness screening instrument (described in Chapter II). Among appendixes are a low physical vitality flow chart and activity list, time prescription test directions and form, activities recommended for basic body types, and a list of supply and equipment needs.
