指出了支持--可信度框架理论存在的不足:有些规则即使支持度、可信度都很高,但仍然没有实际意义;关联规则X Y本身没有给用户提供X对Y是起积极作用还是起抑制作用等信息.引入关联规则的相关度及相关规则概念来克服这种不足,同时指出,相关规则不仅给用户提供了更多信息,而且避免了一些无意义规则的产生.  相似文献

Practical independent research projects (IRPs) are a feature of school science in a number of countries. To assess the impact of IRPs on students, a systematic review of the literature was undertaken. Thirty-nine papers met the review inclusion criteria, reporting on work from twelve countries. The review indicates that IRPs are often associated with wider initiatives such as authentic science, problem-based learning, and project-based learning. There is considerable variability in the nature of IRP work in relation to focus, models of provision, assessment, the involvement of external partners such as universities and employers, and funding, and this diversity affects judgements on the quality of the evidence base on impact. The majority of the research reviewed explored areas such as conceptual understanding, motivation to study science once it is no longer compulsory and attitudes to science, and the development of practical skills. Benefits were identified in relation to the learning of science ideas, affective responses to science, views of pursuing careers involving science, and development of a range of skills. Studies focusing on traditionally under-represented groups indicated that such students felt more positive about science as a result of undertaking IRPs. The review findings indicate that further work is needed to enhance the quality of the available evidence, to consider the ways in which IRPs can be validly assessed, to explore more fully the potential benefits for traditionally under-represented groups, and to explore more fully the potential longer-term benefits of participation in IRPs at high school level.  相似文献

This study examined an extended theory of planned behaviour (TPB) model that specified factors affecting students’ intentions to collaborate online for group work. Past behaviour, past experience and actual behavioural control were incorporated in the extended TPB model. The mediating roles of attitudes, subjective norms and perceived behavioural control were also examined. Data were collected from primary and secondary students in Hong Kong (N = 957). The partial least square approach to structural equation modelling was used to analyse the a priori hypothesised model. In general, the model fitted the data very well and the major relationships were found to be significant. The results indicated that past experience and actual behavioural control played individual roles in the model. Theoretical and practical implications are considered in this study.  相似文献

This article describes the results of a study into the utility of the SVI model, a model in which internal and external evaluation are balanced. The model consists of three phases: school self‐evaluation, visitation and inspection. Under the guidance of school consultants, 27 Dutch primary schools have built up two years of experience with the SVI model. The results show that the school leaders developed a positive attitude towards school self‐evaluation and visitation. They found that both self‐evaluation and visitation have improved their insight into the quality of the school. However, a content analysis of the school self‐evaluation reports shows that the school self‐evaluations are often of low quality. For example, it appeared that most of the self‐evaluation reports do not provide answers to questions the schools have formulated at the beginning of the self‐evaluation. Moreover, the teams of critical friends and the inspectors concluded that the school self‐evaluations do have many shortcomings. Based on these results, we conclude that school self‐evaluation is a very difficult task for most schools. It is therefore crucial that schools receive external support and that they build up experience with school self‐evaluations over a period of years.  相似文献

This study draws on information from 11 in‐depth interviews, two focus groups and 72 written questionnaires to evaluate an extra‐curricular environmental education programme on forestry designed for preparatory school students from a small rural community in Mexico. Specifically, the study assessed the impact of the programme on the ecological knowledge of 72 students. Qualitative feedback suggests that students learnt about forestry, acquired greater awareness of the importance of conservation for the local environment and enjoyed the participatory teaching methods used in the programme. Quantitative results show a positive and significant association between the number of times a student participated in the programme and the student’s ecological knowledge. Students who participated in the programme once had a 16.3% higher knowledge on ecological concepts and knew, on average, 1.5 more local forest plants than students who never attended it (p<.001). Findings suggest that the inclusion of participatory environmental education programmes in preparatory schools would improve the acquisition of ecological knowledge. Further research could consider the consistency of the findings by replicating participatory methods presented here and by using an experimental research design.  相似文献

Lots of papers are being published about e-learning in engineering education. In these papers, positive experiences and aspects seem to overshadow negative ones. However, there are still some problematic sides worth studying. In order to improve its quality these should receive broad attention too. We present an explicit two-sided evaluation of the STUDIO e-learning project carried out at TU Delft in the Netherlands. STUDIO was set up as a Technology and Society course for all first-year students at TU Delft. Given the expected numbers of students, labour-extensivity was an important aim. STUDIO was introduced in three faculties. At the SEFI-conference 2002 the project was evaluated by its designers using student-questionnaires. In this article teachers describe their experiences with STUDIO over some years. Together it gives rise to a balanced view of e-learning in engineering education and provides a good base for improvement.  相似文献

In this study, a comprehensive educational effectiveness model is tested in relation to student's civic knowledge. Multilevel analysis was applied on the dataset of the IEA Civic Education Study (CIVED; Torney-Purta, Lehmann, Oswald, & Schulz, 2001 Torney-Purta, J., Lehmann, R., Oswald, H. and Schulz, W. 2001. Citizenship and education in twenty-eight countries: Civic knowledge and engagement at age fourteen, Amsterdam, The Netherlands: IEA.  [Google Scholar]), which was conducted among junior secondary-school students (age 14), their schools, and their teachers. In total, 28 countries, 4,136 classrooms, and 93,565 students were included in the analysis. The results indicated that the influences on students' civic knowledge are multilevel. Students' civic knowledge and skills were partially explained by individual characteristics, by factors related to quality and opportunities for civic learning offered by classrooms and class composition, and by factors at the national context level. We conclude that most effectiveness factors are relevant for the field of civic and citizenship education and that schooling and educational policy matter for students' success in this field.  相似文献

An attempt was made to evaluate what is tested and how it is tested in the IELTS academic test from a thinking-based perspective. The analysis framework is an incorporation of Bloom’s taxonomy of educational objectives and Bachman’s classification of language knowledge. It is found that the IELTS test exemplifies an assessment of test-takers’ language knowledge and cognitive processes.  相似文献

The United Kingdom (UK) is not alone in its decision to move forward in major ways with technological provision in schools, and has had the experience of a wide range of evaluation studies conducted over many years on which to base its planning. The author argues in this paper that neither this basis nor the methods used will necessarily equip all future needs and requirements when planning and implementing such provision, because of the shifting contextual flux in which developments are taking place, particularly regarding the fundamental position of education within society. The author considers issues facing those involved in the strategic evaluation of educational technologies, when meeting future demands.  相似文献
