Effort on homework in grades 5-9: development, motivational antecedents, and the association with effort on classwork     

Trautwein U  Lüdtke O  Kastens C  Köller O 《Child development》2006,77(4):1094-1111

In 2 studies, an expectancy-value framework was applied to investigate effort expended on mathematics homework. In Study 1 (2,712 students in grades 5, 7, and 9; mean age=13.37 years), lower homework effort was found in higher grades. The effects of intrinsic value on homework effort were higher in the older cohorts, whereas the effects of the expectancy component were lower. In Study 2 (571 students in grades 8 and 9; mean age=14.72), an expanded expectancy-value framework was found to explain both homework and classwork variables. The means for effort and value were lower for homework than for classwork; these differences were partly moderated by students' conscientiousness. The implications of homework behavior and motivation for developmental research are highlighted.  相似文献   

4mM乳酸阈算法比较——以赛艇三级测试为例     

黎涌明  季健民  陈小平  乌里·哈特曼 《体育科学》2012,32(10):73-76

为探究运用内插法和指数回归法计算的4mM乳酸阈的差异性和相关性,选用79组赛艇三级测试中的血乳酸和功率数据,分别运用内插法和指数回归法算得79对4mM乳酸阈(P4-内插法和P4-指数回归法).研究结果表明,无论分赛艇级别与否,P4-内插法和P4-指数回归法之间没有显著性差异.P4-内插法(x)和P4-指数回归法(y)间的直线回归方程分别为:y=0.983x+6.4885 (n=38,r=0.978,男子公开级),y=1.0138x-0.2885(n=20,r=0.988,男子轻量级),y=1.1042x-17.63(n=8,r=0.998,女子公开级),y=0.9904x+3.64 (n=13,r=0.990,女子轻量级),y=0.997x+2.9208 (n=79,r=0.998,全体数据).运用内插法和指数回归法计算的4mM乳酸阈可以进行比较.建议在运用4mM乳酸阈监控和评价运动员有氧能力的长期过程中采用一种恒定的计算方法.  相似文献   

Interactive journal concept for improved scientific publishing and quality assurance     

Ulrich Pschl 《Learned Publishing》2004,17(2):105-113

Many scientific publications are careless, useless or false, and inhibit scholarly communication and scientific progress. This is caused by the failure of traditional journal publishing and peer review to provide efficient scientific exchange and quality assurance in today's highly diverse world of science. The most promising way to improve matters is a two‐stage (or multi‐stage) publication processes with interactive peer review and public discussion in new and traditional scientific journals. A concept for such interactive scientific journals is outlined, and its applicability is demonstrated by the open access journal Atmospheric Chemistry and Physics.  相似文献   

The Transition from Higher Education to Employment in Europe 1     

Ulrich Teichler 《Higher Education in Europe》1998,23(4):535-558

The study of the so‐called transition phase in the lives of young people as they move from higher education graduation to employment is becoming an important area of study. A thorough understanding of the process contributes to a general understanding of the link between higher education and employment. The transition phase is examined from an international comparative perspective. Transition can be “smooth” or “rough”, Japan being known as having, by and large, the smoothest and the most institutionally aided process of transition. The type of institution from which one graduates plays a role in the type of transition process that one will experience, but it does not follow that graduates of applied programmes and institutions (Fachhochschulen) will have an easier time than graduates of traditional universities. The subject as a whole, that is filled with subtleties, clearly deserves to be the object of additional study.

Internationalisation as a Challenge for Higher Education in Europe   总被引：6，自引：2，他引：4  

Teichler  Ulrich 《Tertiary Education and Management》1999,5(1):5-22

'Internationalisation' became a key theme in the 1990s both in higher education policy debates and in higher education research. Starting off from a heterogeneous set of phenomena, internationalisation does not merely mean varying border-crossing activities on the rise anymore, but rather substantial changes: first, from a predominantly 'vertical' pattern of cooperation and mobility towards the dominance of international relationships on equal terms; second, from casuistic action towards systematic policies of internationalisation; third, from disconnection of specific international activities on the one hand and on the other internationalisation of the core activities towards an integrated internationalisation of higher education. Though higher education policy remains predominantly shaped on a national level and tends to underscore specific traditions and conditions of individual countries, the responsibility of individual institutions of higher education in Europe for their own future grows in the process internationalisation which is accompanied, among others, by growing pressure for diversity and increasing popularity of managerialism as well as by a policy of the European Commission which seems to favour de-nationalisation of higher education.  相似文献

Different systems—Similar challenges? Factors impacting the motivation of German and U.S. teachers to become school leaders     

Dawson R. Hancock  Ulrich Müller 《International Journal of Educational Research》2009,48(5):299-306

In the United States and Germany, effective school leadership is pivotal to a school's success. Yet in each country, attracting and retaining qualified school leaders is a formidable challenge. This study compares the influence of possible motivators and inhibitors that impact teachers’ decisions to become principals in the two countries. Survey responses of 311 U.S. students in principal preparation programs in the United States and responses of 117 German students in similar programs in Germany indicate that many factors that motivate and inhibit U.S. and German teachers to become school leaders are similar. The results also reveal areas in which the U.S. and Germany may learn from each other regarding motivators and inhibitors to becoming school administrators.  相似文献   

Perceptions of national identity and attitudes toward immigrants and immigration in Canada and Germany     

Victoria M. Esses  Ulrich Wagner  Carina Wolf  Matthias Preiser  Christopher J. Wilbur 《Int J Intercult Relat》2006,30(6):653

In the current research, we examined whether promoting an inclusive national ingroup that includes both immigrants and nonimmigrants would improve attitudes toward immigrants and immigration among members of receiving societies. We also determined whether one's nation of citizenship and individual differences in social dominance orientation would moderate the effects. Participants were 126 Canadian students and 282 German students, who completed a measure of social dominance orientation and were then asked to respond to a series of questions designed to heighten the salience of national identity (national identity), promote a national ingroup that includes immigrants (common national ingroup), or irrelevant questions (control). The dependent measures included attitudes toward immigrants and immigration, and subtle prejudice toward immigrants. Results revealed that the manipulation of a common national ingroup successfully promoted more positive attitudes toward immigrants and immigration among higher social dominance oriented Canadian participants, but tended to have detrimental effects on the attitudes of higher social dominance oriented German participants. Results are discussed in terms of the importance of considering the context in which groups are situated, as well as implications for developing strategies to promote harmony between immigrants and members of receiving societies.  相似文献
