Reviews the rationale underlying, characteristics of, and available research on four popular elementary school affective programs—the “Human Development Program,” “Developing Understanding of Self and Others,” “Toward Affective Development,” and “Dimensions of Personality.” It is concluded that despite problems such as broadly stated objectives, limited field testing, and poorly conducted and contradictory outcome research, several of the programs do appear to have some merit if used consistently for several months of the school year.  相似文献

Aerodynamic drag in cycling: methods of assessment   总被引:1,自引:0,他引:1  
When cycling on level ground at a speed greater than 14 m/s, aerodynamic drag is the most important resistive force. About 90% of the total mechanical power output is necessary to overcome it. Aerodynamic drag is mainly affected by the effective frontal area which is the product of the projected frontal area and the coefficient of drag. The effective frontal area represents the position of the cyclist on the bicycle and the aerodynamics of the cyclist-bicycle system in this position. In order to optimise performance, estimation of these parameters is necessary. The aim of this study is to describe and comment on the methods used during the last 30 years for the evaluation of the effective frontal area and the projected frontal area in cycling, in both laboratory and actual conditions. Most of the field methods are not expensive and can be realised with few materials, providing valid results in comparison with the reference method in aerodynamics, the wind tunnel. Finally, knowledge of these parameters can be useful in practice or to create theoretical models of cycling performance.  相似文献

Based on Parrot's work with college students, a six‐activity acquaintance rape prevention program for first‐year high school students living in a rural South Carolina community was implemented and evaluated. The program decreased students' acceptance of rape myths compared with non‐participating students both on a scale developed by Burt and on additional items measuring acquaintance rape. Attitudes toward dating violence did not change. Research limitations are discussed, and practical suggestions for sex education are presented.  相似文献

Thirty learning-disabled and 30 normally achieving fourth-grade boys experienced failure on a problem-solving task, following which they received either tutor-assistance or self-instructional training to induce success in coping with failure, or a no-training condition. Training effects were assessed on a subsequent problem-solving task and a measure of continuing motivation. Tutor-assistance training was more effective than self-instructional training for decreasing the number of problems on which learning-disabled boys gave up prior to solution. Compared with their untrained controls, learning-disabled boys with tutor-assistance training gave up less often and solved more problems. Continuing motivation increased with learning-disabled boys who received tutor-assistance training and normally achieving boys without training. Untrained normal achievers attributed failure to adoption of specific task strategies, while untrained learning-disabled boys attributed failure to task difficulty. It was suggested that characteristics of learned helplessness were apparent in the impaired performance of the learning-disabled boys. Normal achievers appeared to have developed active and independent strategies for coping with failure.  相似文献

The Covid-19 pandemic has challenged medical educators internationally to confront the challenges of adapting their present educational activities to a rapidly evolving digital world. In this article, the authors use anatomy education as proxy to reflect on and remap the past, present, and future of medical education in the face of these disruptions. Inspired by the historical Theatrum Anatomicum (Anatomy 1.0), the authors argue replacing current anatomy dissection laboratory (Anatomy 2.0) with a prototype anatomy studio (Anatomy 3.0). In this studio, anatomists are web-performers who not only collaborate with other foundational science educators to devise meaningful and interactive content but who also partner with actors, directors, web-designers, computer engineers, information technologists, and visual artists to master online interactions and processes in order to optimize students' engagement and learning. This anatomy studio also offers students opportunities to create their own online content and thus reposition themselves digitally, a step into developing a new competency of stage presence within medical education. So restructured, Anatomy 3.0 will prepare students with the skills to navigate an emergent era of tele and digital medicine as well as help to foreshadow forthcoming changes in medical education.  相似文献
