This conceptual paper explores three areas of research collaboration: (a) effectively harnessing differences, (b) setting defensible boundaries and (c) gaining legitimate authorization. The focus is on their potential lessons for individuals leading and managing research collaborations, evaluation of research partnerships and areas for further investigation. Examples from three partnerships - building the atomic bomb, the Human Genome Project and the World Commission on Dams - are used to highlight key elements of the ideas presented. The paper provides a framework for systematically thinking about integration of different perspectives and other elements essential to any particular collaboration. It also sketches out ideas for (1) managing differences which may destroy partnerships, (2) deciding what the collaboration should encompass, (3) understanding and accommodating forces which may distort what the collaboration is able to achieve, and (4) enlisting necessary supporters while preserving research independence. 相似文献
Reducing the number of school years until graduation from academic-track secondary schooling (“G8”) has been one of the most important structural changes to schooling in the past few years. The reduction is one element of more compressed and accelerated processes in institutional education implemented over the last decade. The extent to which the changes in the systemic context of schooling affect organizational and instructional processes and results, or the school actors concerned (teachers, pupils and their families), has only been insufficiently investigated so far. This contribution provides an overview of this barely investigated topic. Following a review of the historical developments, the normative debates regarding reduced school time will be presented and then compared with the current state of research. The paper closes with an analysis of different models for organizing the reduction of school years and an outlook on current developments. 相似文献
Recent studies (Chiviacowsky & Wulf, 2002, 2005) have shown that learners prefer to receive feedback after they believe they had a “good” rather than “poor”trial. The present study followed up on this finding and examined whether learning would benefit if individuals received feedback after good relative to poor trials. Participants practiced a task that required them to throw beanbags at a target with their nondominant arm. Vision was prevented during and after the throws. All participants received knowledge of results (KR) on three trials in each 6-trial block. While one group (KR good) received KR for the three most effective trials in each block, another (KR poor) received feedback for the three least effective trials in each block. There were no group differences in practice. However, the KR good group showed learning advantages on a delayed retention test (without KR). These results demonstrated that learning is facilitated if feedback is provided after good rather than poor trials. The findings are interpreted as evidence for a motivational function of feedback. 相似文献
Abstract The leg strength of 70 college men was measured in a position designed to involve the power thrust of the major muscle groups used in the vertical jump. The subjects then performed a modified Sargent jump that used no arm snap. Although the reliability of all measures was high, individual differences in the ratio of tested strength to body mass showed only a low and nonsignificant correlation with jumping performance. The results are interpreted to support the hypothesis that strength exerted against a dynamometer involves a different neuromotor pattern than strength exerted by the muscles during a movement. Tables of means, variabilities, and intercorrelations are included in the report. 相似文献
A frequent observation in the school context is that opportunities to learn from errors are often missed. However, a positive error climate may support learning from errors. For the school subject of mathematics, some findings about characteristics of the error climate already exist. But, a comparison of the error climate between different school subjects is still pending. In the present study, it is analyzed whether the error climate differs in different school subjects and whether the same interrelations between the ways in which individuals deal with errors can be found in these different school subjects. In a study with 937 students from 48 classrooms from grades 5 to 7, in different secondary schools in Germany and Austria, we assessed the error climate and individual reactions following errors in mathematics, German, and English. Small mean differences between mathematics and the two language subjects were yielded. In addition, we found medium-sized correlations between the error climate measures in the three school subjects. However, the same pattern of interrelations between error climate and the way individuals deal with errors for all three school subjects could be shown. The results suggest that the perception of the error climate is rather similar in different school subjects. This has implications, for instance, for interventions that aim at fostering the error climate.
