Measurement is presented here as a means of enabling health and physical education programs to assume their place as indispensible phases of the educational process. Measurement is considered vital to health and physical education programs; teachers in these fields are admonished to turn to measurement activities as readily and as naturally as they turn to the other activities of their programs. In Part One, the current trends of health and physical education, a consideration of the desirable qualities to measure, and an explanation of definite administrative procedures to use when putting tests to practical use are found. In the first chapter, an orientation to the place of physical education in our culture is presented, and the objectives of health and physical education are stated. In the second chapter, criteria for selecting tests from a scientific point of view are considered so that health and physical educators may be prepared to evaluate tests themselves. The importance of each objective of health and physical education programs, the educational and administrative procedures for its realization, and the various phases of physical fitness testing are presented in Part Two. In Part Three, social efficiency and motor ability tests are described, evaluated, and their uses indicated. A similar presentation is made for skill and knowledge tests in Part Four. Part Five is devoted to administrative problems and the process of inaugurating measurement programs. Appendix A includes statistical procedures essential for the construction of tests. Scoring tables necessary to the use of tests described in the text appear in Appendix B. Throughout the text, 119 tests and test batteries appear that may be given and scored directly from the text; 151 other tests are described, evaluated, and their sources provided. (MM)
