This quantitative study investigated the relationship between teacher dispositions, subject content knowledge, pedagogical content knowledge, and reasons that school principals recommend non-renewal of probationary teachers' contracts. Principals in the Southeastern Unites States completed an e-mailed survey. Two nonparametric tests, Kruskal-Wallis and Mann Whitney U, were used to statistically analyze group responses. Principals reported that they observed most a lack of pedagogical content knowledge from ineffective teachers and they prioritized the importance of instructional skills in deciding whether to non-renew a teacher contract. Principals identified teacher integrity, dependability, and honesty as important dispositions. The studies' findings are important for universities that prepare preservice teachers and also for the planning of professional development initiatives. The study findings suggest that principals tend to view dispositions as personality characteristics rather than as teacher competencies and that teacher expertise in both subject content and pedagogy must be woven together. 相似文献

This paper uses a possible selves theoretical framework to examine whether and how adolescent girls' images of themselves as future scientists change during their transition from high school to college. Forty-one female high school graduates from diverse ethnic and socioeconomic backgrounds, who had enrolled in an intensive math and science program while in high school, participated in interviews focused on their perceptions of factors that influenced their career plans over time. Participants suggested that career-related internships and intensive academic programs, especially those that yielded important mentoring relationships, were contexts in which they negotiated career-related possible selves and subsequent career plans. 相似文献

In two experiments using a radial-arm maze, pairs of rats made choices among eight maze locations, each containing a large
quantity of one of two food types. The choices made by 1 rat affected the choices made by the other rat. Under most conditions,
visits by 1 rat increased the tendency of the other rat to subsequently choose that maze location. However, the effect depended
on the quality of the food available in a particular location. When it was possible for the rats to observe each other on
the maze arms and a rat had experienced that a location contained the less preferred food type, a previous visit to that location
by the foraging partner decreased the tendency to visit that location. These effects are attributed to working memory for
the spatial choices of another rat, and they indicate that memory produced by a rat’s own visit to a maze location is integrated
with memory for the behavior of another rat to determine spatial choice 相似文献

While the case method has been used in teaching social work practice for many years, its use as an evaluation tool is less common. This analysis describes the use of the case method in a comprehensive examination for MSW students in an Administration concentration. After a brief review of the issues related to student outcome assessment and the curriculum of the Administration concentration, a case debriefing framework is described, along with examples of student responses. The analysis concludes with a discussion of issues and implications for future research. 相似文献

ABSTRACT: To create effective educational interventions that address the food safety informational needs of youth, a greater understanding of their knowledge and skills is needed. The purposes of this study were to explore, via focus groups, the food‐handling responsibilities of middle school youth and obstacles they face in practicing safe food handling and develop recommendations for the design of food safety interventions for youth. Most youth reported that they prepared food at least once weekly and rated learning to prevent foodborne illness as important. Youth knew that food could make them sick, described foodborne illness as resulting from “something” getting into food, not cooking food “right,” or the food going bad. Most responses lacked details, suggesting knowledge was basic. Nearly all were interested in learning about food safety. Barriers that deterred them from learning about food safety were time and feeling they were not susceptible to foodborne illness. To overcome barriers, youth suggested focusing on the seriousness of and risks for foodborne illness, using a serious but comical educational approach, and using hands‐on educational media. Parents highly rated the importance of and degree to which they wanted youth to learn about food safety. Parents felt that their children had moderate levels of food safety knowledge, but many questioned whether they practiced food safety procedures when unsupervised. Parents felt that food safety education needed to be taught and reinforced in school and at home. After having reviewed youth and parent data, food safety experts proposed recommendations for youth‐focused food safety education that paralleled current consumer food safety initiatives. 相似文献

Throwers, jumpers, and combined events athletes require speed, strength, power, and a wide variety of technical skills to be successful in their events. Only a handful of studies have assessed the nutritional needs of such athletes. Because of this, recommendations for nutritional requirements to support and enhance training and competition performances for these athletes are made using research findings from sports and exercise protocols similar to their training and competitive events. The goals of the preparation cycle of nutrition periodization for these athletes include attaining desirable body weight, a high ratio of lean body mass to body height, and improving muscular power. Nutritional recommendations for training and competition periods include: (1) meeting energy needs; (2) timing consumption of adequate fluid and electrolyte intakes before, during, and after exercise to promote adequate hydration; (3) timing consumption of carbohydrate intake to provide adequate fuel for energy demands and to spare protein for muscle repair, growth, and maintenance; (4) timing consumption of adequate protein intake to meet protein synthesis and turnover needs; and (5) consuming effective nutritional and dietary supplements. Translating these nutrient and dietary recommendations into guidelines these athletes can apply during training and competition is important for enhancing performance. 相似文献
