Abstract

Four sprint starting positions—the bunch, medium, elongated, and hyperextended—were compared on mean elapsed times at distances of 10 and 30 yd. Averages of three starts for each of 30 inexperienced college undergraduate males on each type of start were derived from electronically-controlled measures, the times for both distances being recorded from the same start. Statistical analyses indicated significantly lower elapsed times with the hyperextended starting position.  相似文献

Abstract

This article describes a project that uses videotaped segments of “best practice” teaching methods with freshman practicum students in a midsized university. The rationale, process of collecting teaching segments, and preliminary use of two tapes are presented. Initial response suggests that using videotaped teaching segments with preservice teaching majors is a positive approach to introducing students to the intricacies of teaching and learning.  相似文献

Abstract

Since the publication of the Crowther Report in 1959 there have been seven major proposals for reducing the degree of specialisation in England and Wales and postponing its onset. This article examines the history and nature of these proposals and the reasons for their failure. Its main contentions are that the historical opposition to any central or local control of the school curriculum has made it very difficult to determine what actually was happening in the schools or what external forces controlled the pattern of studies: and that in the absence of any authority controlling the pattern of the curriculum, it was almost impossible that any proposals for change would be implemented.  相似文献

The impact of an inservice program on practitioners’ gerontological knowledge and attitudes was examined. A nonequivalent control group design was used to conduct the study. The experimental group was made up of geriatric recreational service providers attending the first of two annual one‐week inservice educational programs. An outdoor resource management undergraduate level class served as the control group. The experimental group relative to the control group underwent a significant increase in their gerontological knowledge. Neither group experienced a significant change in their attitudes regarding the social value of the elderly or personal anxiety toward aging. The amount of change experienced in gerontological knowledge by program participants was significantly influenced by the degree of contact the individual had had with elders but not by their educational background. Educational background and degree of contact were not significantly associated with change in gerontological‐related attitudes. Implications for persons involved in designing and developing educational programs are discussed.  相似文献
