The history of education and schooling is characterised by not only the attainment of results but also ongoing critique of the existing situation in education and schooling. Developers and researchers are, as a result, constantly seeking new strategies and methods for the improved implementation of innovations in actual educational practice. The central question is which factors and which conditions facilitate the effects of innovations. In an attempt to answer this question, many educators will not so much be concerned with objective structural factors such as available funds, classmates, et cetera. They will be concerned, rather, with the questions of which socially constructed realities and which particular forms of involvement on the part of teachers, school administrators, and counsellors facilitate successful innovation. In our search for an answer to these questions, moreover, we will be guided by a cultural-individual perspective on innovation. Traditional innovative strategies – and, in particular, large scale strategies – seem not always suitable to deal with today's educational problems. Alternative scenario's for the management of innovations are considered. 相似文献

The aim of this study was to propose a new force parameter, associated with swimmers’ technique and performance. Twelve swimmers performed five repetitions of 25 m sprint crawl and a tethered swimming test with maximal effort. The parameters calculated were: the mean swimming velocity for crawl sprint, the mean propulsive force of the tethered swimming test as well as an oscillation parameter calculated from force fluctuation. The oscillation parameter evaluates the force variation around the mean force during the tethered test as a measure of swimming technique. Two parameters showed significant correlations with swimming velocity: the mean force during the tethered swimming (r = 0.85) and the product of the mean force square root and the oscillation (r = 0.86). However, the intercept coefficient was significantly different from zero only for the mean force, suggesting that although the correlation coefficient of the parameters was similar, part of the mean velocity magnitude that was not associated with the mean force was associated with the product of the mean force square root and the oscillation. Thus, force fluctuation during tethered swimming can be used as a quantitative index of swimmers’ technique. 相似文献

Individual time preference determines schooling enrolment. Moreover, smoking behavior in early ages has been shown to be highly related to time preference rates. Insofar as discount rates are uncorrelated to ability, predicting school enrolment by discount rates can get rid of the ability bias in an earnings regression. Accordingly, we use smoking at age 16 as an instrument for schooling. Doing this for Austrian cross-sectional data, we find no evidence of ability bias in a simple earnings regression; the results are more mixed if family background is also included. 相似文献

With respect to the guiding German-language concept of ?Bildung“ (education) within the context of PISA a fundamental process has taken place in Germany of restructuring and redefining educational goals. Current educational science is determined by this process and by the initiation of empirical educational research leading to serious development projects. In this contribution examples of all of them are presented and analyzed with regard to their fundamental strengths and limitations directed towards an elaborate imagination of universal education within our knowledge society. Based on the analysis of the thus remeasured educational scientific landscape, the question of the relationship between empirical educational research and educational theory does not indicate the expected polarity between educational theory and educational research results. On the contrary there can rather be found a plurality of sometimes competing and partly complementary forms of science of the old and of the new type. Scientists who wish to remain sovereign in the field of post-PISA educational science are required to show a broad competence covering the different form of science in order to open new perspectives of cooperation. 相似文献

Croatian 1st‐year and 3rd‐year high‐school students (N = 170) completed a conceptual physics test. Students were evaluated with regard to two physics topics: Newtonian dynamics and simple DC circuits. Students answered test items and also indicated their confidence in each answer. Rasch analysis facilitated the calculation of three linear measures: (a) an item‐difficulty measure based upon all responses, (b) an item‐confidence measure based upon correct student answers, and (c) an item‐confidence measure based upon incorrect student answers. Comparisons were made with regard to item difficulty and item confidence. The results suggest that Newtonian dynamics is a topic with stronger students' alternative conceptions than the topic of DC circuits, which is characterized by much lower students' confidence on both correct and incorrect answers. A systematic and significant difference between mean student confidence on Newtonian dynamics and DC circuits items was found in both student groups. Findings suggest some steps for physics instruction in Croatia as well as areas of further research for those in science education interested in additional techniques of exploring alternative conceptions. © 2005 Wiley Periodicals, Inc.
