School closures have been common in rural areas since the middle of the last century, when new and modern schools replaced small old‐fashioned schools with only one or two classrooms. Due mainly to the industrialisation of farming and hastened by the merging and globalisation of industry, the last 50 years have seen a migration of people from rural areas to large towns. This has caused closures of schools built in the 1950s and 1960s, which had been the pride of and a sign of development in local societies. These closures most often give rise to heated debate, the main cry of protest being that the closure of the school is a death‐blow to the local society. The present study is based on a qualitative analysis performed in 2003 of 30 Danish school closures in the period 1990–1999. The results show that school closure in itself does not have the devastating effects mentioned in the debate. The main problem for local societies is a lack of people and thus lack of human capital, and in remote areas and on small islands school closure is a sign of a community in the final phase of the death process, not a cause.  相似文献

This paper outlines an epistemological conception which attempts to relate the formal aspects of mathematical proof to its pragmatic dimensions. In addition to the key concept of application, the paper makes use of several concepts from the domain of analytical philosophy, to present a view of proof that might best be categorized as a dialectical one. A number of implications for teaching are discussed.  相似文献

Learning behaviors of employees can be either formalized (in the form of programmed events and visits) or informal (in the form of spontaneous interaction and knowledge sharing). We investigate the effect that both types of learning behaviors have on interorganizational learning of substantive knowledge in the context of an alliance. We also look at the effects that the two forms of learning behavior have on each other. We find that while informal learning behaviors have a consistently positive effect on the learning outcome and on formal learning behaviors, this is not so for formal learning behaviors. The effect of formal behaviors on both learning outcome and informal behaviors, while positive, diminishes at higher levels. This leads us to conclude that although both informal and formal learning behaviors foster interorganizational learning, too much formalization obstructs learning. Similarly, while formally programmed behaviors do encourage informal learning behaviors of the boundary spanners, an excess of formalization stifles them.  相似文献

This literature study deals with the issue of how to conceptualize the supervisory behaviour of mentor teachers in mentoring dialogues by systematically examining empirical literature on key aspects of mentor teachers’ behaviour during dialogues with prospective teachers. From the findings a model is derived which can be used to study mentor teachers’ behaviour in mentoring dialogues. The model may be helpful in the further development of the quality of mentor teachers’ behaviour in mentoring dialogues.  相似文献

In the context of developing mentor teachers' use of supervisory skills, two consecutive studies were conducted, using stimulated recall. Firstly, with eight participants, an instrument was developed to categorize contents of interactive cognitions. Secondly, with 30 participants, the instrument was applied to uncover contents of mentor teachers' interactive cognitions, before and after training in supervisory skills. After training, mentor teachers demonstrate an increased awareness of their use of supervisory skills. This indicates that mentor teachers not only seem to emphasize pupil learning and needs when conducting a mentoring dialogue, but simultaneously focus on their own supervisory behaviour.  相似文献

Abstract

A large proportion of a child's day is spent at school interacting with certain physical surroundings, teachers, and school friends. Thus, schools could have a marked impact on establishing physical activity habits. The aim of the present study was to assess between-school variation in physical activity, aerobic fitness, and organized sports participation. Altogether, we tested 1766 nine- and fifteen-year-old children attending 242 school classes at 35 different schools in Denmark in 1997–2003. The intra-class correlation coefficient (ICC) for objectively assessed physical activity ranged between 0.06 and 0.18 depending on the dimension of physical activity and the time considered (i.e. school time vs. leisure time). For aerobic fitness, an ICC of 0.10 was observed, whereas that for organized sports participation ranged between 0.01 and 0.10 depending on the age group. Studying between-school variation in physical activity provides information about the extent to which children adjust their physical activity habits according to the social and environmental circumstances that they share, and helps to plan future school-based physical activity studies, especially in terms of sample size and power calculation.  相似文献

Motion capture through inertial sensors is becoming popular, but its accuracy to describe kinematics during changes in walking speed is unknown. The aim of this study was to determine the accuracy of trunk speed extracted using an inertial motion system compared to a gold standard optical motion system, during steady walking and stationary periods. Eleven participants walked on pre-established paths marked on the floor. Between each lap, a 1-second stationary transition period at the initial position was included prior to the next lap. Resultant trunk speed during the walking and transition periods were extracted from an inertial (240 Hz sampling rate) and an optical system (120 Hz sampling rate) to calculate the agreement (Pearson’s correlation coefficient) and relative root mean square errors between both systems. The agreement for the resultant trunk speed between the inertial system and the optical system was strong (0.67 < r ≤ 0.9) for both walking and transition periods. Moreover, relative root mean square error during the transition periods was greater in comparison to the walking periods (>40% across all paths). It was concluded that trunk speed extracted from inertial systems have fair accuracy during walking, but the accuracy was reduced in the transition periods.  相似文献
