This paper analyses tuitional practices after a major curriculum change (2005) in primary schools of Turkey. Group discussions conducted with teachers and parents in five maximally contrasting schools (e.g. schools in a squatter and a middle-class neighbourhood of Istanbul) show that tuitional practices, being only ‘loosely coupled’ with the official curriculum, are strongly influenced by generation-specific orientations in teachers’ organisational milieus, by orientations prevalent in the social milieus of pupils and their parents, and by different forms of capital on the part of teachers, parents and school organisations. Combined with empirical analysis, the paper proposes a theoretical framework that complements the assumptions of New Institutionalism by using the basic concepts of the sociology of knowledge and Bourdieu’s concept of capital. This framework offers a new way to understand the intrinsic logic of the growing differences and inequalities within and between school organisations in complex societies. 相似文献

One way to fascinate, engage, arouse curiosity, motivate, and stimulate intellectual development in learning scientific concepts is to use counterintuitive questions. These questions make students aware of the inadequacies of their own thinking by exposing them to situations whose outcomes are inconsistent with what they would expect. In this study, a counterintuitive dynamics test (CIDT) is developed and administered to high school students along with the force concept inventory (FCI). After expert reviews, the initial version of the test consisting of 39 questions was administered to 87 students as a pilot study. After item analysis, a final version of 30 questions was developed; its internal consistency reliability coefficient was calculated as 0.826. The CIDT and FCI were administered to 229 students from 9 different high schools in Turkey. The results indicated that while in FCI students were mostly affected by everyday experiences and while in CIDT by carelessness and a superficial approach. Average scores for both tests were roughly equal and low. The results showed that the CIDT is a new test that measures another dimension of dynamic concepts and should be used along with the FCI. 相似文献

In this paper we describe the design of a groupware framework, CIRLab, for experimenting with collaborative information retrieval (CIR) techniques in different search scenarios. This framework has been designed applying design patterns and an object-oriented middleware platform to maximize its reusability and adaptability in new contexts with a minimum of programming efforts. Our collaborative search application comprises three main modules: the Core, which supports various modern state-of-the-art CIR techniques that can be reused or extended in a distributed collaborative environment; the Facades Mediator, an event-driven notification service which allows easy integration between the Core and front-end applications; and finally, the Actions Tracker, which allows researchers to perform experiments on the different elements involved in the collaborative search sessions. The applying of this framework is illustrated through the analysis of the collaborative search-driven development case study. 相似文献

A critical challenge for Web search engines concerns how they present relevant results to searchers. The traditional approach is to produce a ranked list of results with title and summary (snippet) information, and these snippets are usually chosen based on the current query. Snippets play a vital sensemaking role, helping searchers to efficiently make sense of a collection of search results, as well as determine the likely relevance of individual results. Recently researchers have begun to explore how snippets might also be adapted based on searcher preferences as a way to better highlight relevant results to the searcher. In this paper we focus on the role of snippets in collaborative web search and describe a technique for summarizing search results that harnesses the collaborative search behaviour of communities of like-minded searchers to produce snippets that are more focused on the preferences of the searchers. We go on to show how this so-called social summarization technique can generate summaries that are significantly better adapted to searcher preferences and describe a novel personalized search interface that combines result recommendation with social summarization. 相似文献

This paper reports on the second phase of a multi‐country study examining cross‐cultural perspectives of gender and management in universities. The first phase of this research with eight countries found that the representation of women was consistently low, especially at Rector/Vice Chancellor level. In the second phase interviews were conducted with both male and female senior managers including current and former Rectors/Vice Chancellors. The focus of this paper is on the organisational barriers to women becoming and being managers in Turkish and New Zealand universities. Twenty‐four interviews were conducted in Turkey and 26 in New Zealand. Rectors/Vice Chancellors and other senior academic colleagues were found to be crucial in supporting academics into senior management. Barriers discussed include time management and role conflict between work and non‐work life. 相似文献

ABSTRACTThe aim of this investigation was to assess the reliability and validity of the Fitjump system. Fifty-seven participants (age = 22.62 ± 5.24 years, height = 180.69 ± 12.53 cm, body mass = 75.61 ± 9.56 kg) performed three countermovement jump (CMJ) and squat jump (SJ) with a 1-week interval for test and retest reliability. For validity, the participants performed the same jump protocol on the force platform while being simultaneously measured with the Fitjump system. There was excellent test–retest reliability of the Fitjump system for CMJ and SJ with high intraclass correlation coefficient (ICCs) (0.97 and 0.97, respectively), low coefficient variation (CVs) (2.3% and 2.4%, respectively), and low typical error of estimate [(TEE (%)] (4.0% and 4.4%, respectively). For validity, ICCs were extremely high for CMJ and SJ (0.93 and 0.94, respectively), with low TEE (%) (2.9% and 2.0%, respectively). However, Fitjump overestimated jump height for CMJ and SJ (3.54 and 3.37 cm, respectively; p < 0.001) when compared with the force platform. As a conclusion, the Fitjump system demonstrated excellent test–retest reliability and high relationship with a systematic bias for validity. Therefore, the Fitjump system can be used as a portable tool for monitoring vertical jump changes over time, but it should not be used interchangeably with a force platform. 相似文献
