Innovative programs for restructuring the entry phase of mathematics teacher education programs have been implemented at various German universities within the last few years. This article reports about the design and the results of a longitudinal evaluation study of the effectiveness of two of these programs aiming to improve mathematics teacher education by altering the conditions in university teaching (the so-called Teacher Education and Development Study TEDS-Telekom). The development of prospective teachers’ professional knowledge in academic mathematical content knowledge, knowledge in elementary mathematics from an advanced standpoint, and mathematical pedagogical content knowledge from the innovative programs were compared to traditional university programs. The study points out that the innovative programs only partially succeeded in improving the acquisition of professional knowledge for prospective mathematics teachers. 相似文献

AbstractSport facilities are instrumental in keeping the population fit and healthy. Governments worldwide are thus engaged in devising policies, programs and projects for building such facilities, with the aim of providing citizens with opportunities for a healthy lifestyle. This feature is prominent in the Nordic countries, which have incorporated sport, leisure and physical activity into their universal welfare models. Understanding policies and politics for building sports facilities has therefore become a cornerstone in the understanding of conditions for sport and physical activity for all. In this paper, we investigate and compare the national structures for building and managing sports facilities in the Nordic countries, in order to add to the understanding of how policies and politics for building sport facilities can add to or hamper the sport-for-all ambitions salient in most of today’s western societies. 相似文献

In this paper, we attempt to explain the differences between reading and math scores of migrants’ children (8430 daughters and 8526 sons) in 17 OECD destination countries, coming from 45 origin countries or regions, using PISA 2009 data. In addition to the societal gender equality levels of the origin and destination countries (the gender empowerment measure), we use macro indicators of the origin countries’ educational systems, economic development and religions. We find that migrant daughters from countries with higher gender equality levels obtain higher reading scores than comparable migrant sons do (but this is not the case for math scores). In addition, the higher the gender equality levels in the destination countries, the lower the reading and math scores of both male and female migrants’ children in their destination countries. Further analyses suggest it is the difference between gender equality levels, rather than the levels themselves, that explains the educational performance of both female and male migrant pupils. Our results also show the low gender equality level in Islamic origin countries offers a possible explanation for the low educational performance of Islamic pupils, both male and female. Finally, migrants’ daughters seem to perform slightly better educationally, compared with migrants’ sons. 相似文献

The problem was concerned with the extent to which cognitive/linguistic functions and domain-specific strategies could predict readers’ text comprehension when working with science texts. Six hypotheses were stated and tested in two prediction studies (N=101 eighth-graders), and one experiment (N=8 pupils of same age). Handal’s reading test was used for classifying pupils into good and poor readers. Two texts, one with a known subject and another with an unknown theme were imposed pupils as science reading tasks. Questionnaires and tests concerning cognitive and linguistic functions were used as independent variables in the prediction studies. Two different tests were used as independent variables (for text comprehension) in all of the three studies, and one additional criterion test (writing essays on main ideas in the texts) was applied in the experient. The experiment was organized as a 2x2 factorial design where text type and reading skill were the factors. According to the results, 5 of the 6 hypotheses could not be rejected, i.e., general concept information was the most significant predictor of science text comprehension. Furthermore, text based on a subject known to the reader always surpassed text with an unknown subject as to text comprehension. Similarily, across-domain strategies were more closely related to reading comprehension than domain-specific strategies. 相似文献

In computer gaming situations in kindergartens, the pre-school teacher’s function can be viewed in a continuum. At one extreme is the teacher who takes an intervening role and at the other extreme is the teacher who chooses to restrict herself/himself to an organising or distal role. This study shows that both the intervening position and the organising or distal role are challenging. An alternative role is an intermediate position in which the teacher is a contributor and encouraging bystander. The term didactic dissonance is suggested to capture the challenges and tensions in didactic situations where teacher and child participate with conflicting roles and expectations. Didactic dissonance may help educators reflect on teacher roles in didactic contexts. 相似文献

The static and dynamic stiffness behaviour of composite golf shafts and their constituent materials 总被引：1，自引：1，他引：0

Golf shafts are normally characterised using static or quasi-static tests, yet the golf swing itself is dynamic. The purpose
of this research was to determine whether stiffness properties obtained from these tests can be used when modelling the dynamic
behaviour of golf shafts made from carbon fibre reinforced polymer (CFRP). Three shafts, matched for all properties except
shaft flex, were subjected to human swing testing by 12 skillful players whilst strains were recorded. Peak principal strains
as well as strain rates increased as shaft flex decreased (p < 0.001). CFRP flat panels with lay-ups similar to those contained in the shafts were constructed and tested statically and
at strain rates between 10−4 and 4 s−1. Some level of strain-rate dependency was found for these panels, but only for strain rates exceeding those seen during a
swing, which suggests that static material tests are appropriate for measuring the dynamic stiffness of golf shafts. 相似文献
