Due to a comparatively weak curricular structure in education faculties, student teachers may determine their study experiences and learning processes largely by themselves, by selecting their own priorities within educational foundation studies. This paper focused on the relationship between individually-chosen educational specializations, self-perceived competence in these chosen fields, and the measured educational knowledge. The study among teacher education graduates in the German state North Rhine-Westphalia showed that the individually chosen priorities within educational courses varied greatly; however, a focus on topics like classroom teaching, learning and development, and creating school environments was discernable. Results revealed that graduates with certain courses of specializations showed a significant higher level of knowledge in self-report in according areas. However, there were only small significant correlations between the self-reported competencies and the educational knowledge measured by the test. The results of the standardized test of educational knowledge indicated that the graduates in fact achieved better test results in their prioritized fields of studies. This suggests that individual course selection in educational foundations does have an effect on subsequent educational knowledge.  相似文献

In this cross-sectional study, we evaluated the body composition and dietary intake of 44 adolescent tennis players. After being divided into two groups (age 10-13 years and age 14-18), the players had their weight, height, and sexual maturation assessed. Dual-energy X-ray absorptiometry was used to assess body composition. Food intake was obtained from a non-consecutive 4-day food record. The data were analysed using the Virtual Nutri v.1.0 software and compared with the present recommendations for adolescent athletes or dietary reference intakes. Body mass index and body fat for tennis practice were adequate for 89% and 71% of the tennis players respectively, regardless of age group. A calorie deficit greater than 10% of energy expenditure was observed in 32% of the sample. Fifty percent of the athletes consumed carbohydrates in accordance with recommended values. Protein and lipid intakes were above recommended values, while fibre, calcium, potassium, magnesium, and folic acid intakes were below recommendation for 98%, 80%, 100%, 100%, and 98% of the tennis players respectively. The observed nutritional deficiencies represent an additional barrier for adolescents engaged in competitive sports to achieve an optimum nutrition to maintain growth, health, and performance.  相似文献

While remarkably positive findings have been presented in research focusing on Sport Education in school settings, investigations on how preservice teachers learn to teach a new curriculum in physical education have been described as ‘the missing link’ in curriculum research. The purpose of this study was to introduce Sport Education to students in a Russian physical education pedagogical college, and to track their understanding of the model through a series of learning experiences. An action research methodology was employed as the main design of this study, which included four experience steps: lecturing, participating, planning and teaching. The most significant finding related to the knowledge that preservice teachers received during their intensive participation. In particular, this cohort of preservice teachers began with the misconception that Sport Education is a model where the teacher is essentially substituted by the students in terms of the operation of the class. However, by the end of the experience, the preservice teachers held the belief that Sport Education is more like a completely different teaching style where the teacher becomes a facilitator of class events. Nonetheless, their previous histories with physical education and their apprenticeships of observation strongly shaped their future intentions to teach the model.  相似文献

As a “public servant” the American school teacher of the twentieth century is the most servile, inconspicuous, conservative, and complacent human being on earth. This fact is due to a vicious chain of circumstances which have been in operation from the early days of American history. In my own experience, I have found three principal forces contributing to the general aura of inertia connected with the teaching profession: (1) undergraduate courses in education (2) public opinion (3) pressure groups.  相似文献

This study examines whether the size of the college earnings premium varies depending on the quality of the match between an individual's degree field and his/her occupation. The study uses the Occupational Information Network (O*NET) to obtain a new measure of the quality of occupational match for a sample of 2268 young adults with post-secondary degrees from the restricted use High School and Beyond (1980/92) data. The study finds that people whose occupations better match their degree fields earn significantly higher returns to post-secondary schooling. This result is robust to controlling for an extensive set of pre-existing differences among individuals, and to accounting for differences in earnings across post-secondary degree fields.  相似文献

This study investigated the effects of the intensity of the protest paradigm frame in news stories about social protests. In contrast to previous research, this experiment examined framing effects in the context of a highly visible and familiar issue. The intensity of the application of the protest paradigm frame and its attendant signifying elements and framing devices were manipulated in television news stories about pro-choice and pro-life protests. Specifically, the high-intensity protest paradigm frame conditions were more critical of the protesters. We tested six hypotheses regarding whether this greater frame intensity would lead viewers to be more negative toward the protesters. Results showed significant main effects of frame intensity for some dependent measures but not others. The findings offer more evidence of framing effects but also suggest limitations on their influence.  相似文献

The article presents the evolution of the bibliographic resources created by Gosudarstvennaia publichnaia nauchno-tekhnicheskaia biblioteka Sibirskogo otdeleniia Rossiiskoi akademii nauk (GPNTB SO RAN) [State Public Scientific-Technological Library of the Siberian Branch of the Russian Academy of Sciences] to provide information support to researchers of SO RAN. The components of these resources are described briefly: bibliographic databases, databases of abstracts, full-text thematic databases, and problem-specific databases. Also discussed are ways to improve these library information products.  相似文献
