科学教育中的探究教学模式发展述评 总被引:3,自引:0,他引:3
当前,伴随着强调以“科学探究”为核心的科学教育改革,世界范围内形成并发展了一些有代表性的科学探究教学模式。“学习环”模式和随后对学习环模式的修订以及由此发展出的数学模式,基本体现了强调科学探究的教学思想的发展过程。近年来的一些研究者仍然在探索新的科学探究教学模式。国际科学教育中的探究教学模式及其发展对于我国的科学教育改革具有重要启示意义。 相似文献

Increasingly, career centers on university and college campuses are making use of the World Wide Web to help their users with a myriad of career related needs. This technological service delivery mode has many advantages that will be briefly reviewed in this article. As well, a computer emphasis has the potential for drastically changing career centers as we know them: their traffic patterns, staffing needs, resource procurement, and perhaps most importantly, their outcomes in the lives of the students who make use of them. This article discusses these changes and through a review of seven critical issues, challenges the reader to closely examine the implications for technology within their own career centers. 相似文献

Most distance learning institutions collect vast amounts of learning data. Making sense of this ‘Big Data’ can be a challenge, in particular when data are stored at different data warehouses and require advanced statistical skills to interpret complex patterns of data. As a leading institute on learning analytics, the Open University UK instigated in 2012 a Data Wrangling initiative. This provided every Faculty with a dedicated academic with expertise data analysis and whose task is to provide strategic, pedagogical and sense-making advice to staff and senior management. Given substantial changes within the OU (e.g. new Faculty structure, real-time dashboards, two large-scale adoptions of predictive analytics approaches, increased reliance on analytics), this embedded case study provides an in-depth review of lessons learned of five years of data wrangling. We will elaborate on the design of the new structure, its strengths and potential weaknesses, and affordances to be adopted by other institutions. 相似文献

For statically indeterminate structure, the internal force will be changed with the translation of the supports, because the internal force is related to the absolute value of the stiffness EI. When the tension is different with the compression modulus, EI is the function of internal force and is not constant any more that is different from classic mechanics. In the other words, it is a nonlinear problem to calculate the internal force. The expression for neutral axis of the statically indeterminate structure was derived in the paper. The iterative program for nonlinear internal force was compiled. One case study was presented to illustrate the difference between the results using the different modulus theory and the single modulus theory as in classical mechanics. Finally, some reasonable suggestions were made for the different modulus structures. 相似文献

In Japan, there has been an increased concern about family and community participation in the childs education. Traditionally, the role of parents and community in Japan has been one of support and less one of active involvement in school learning. Since the government commenced education reforms in the last quarter of the 20th century, a more active role for parents and the community in education has been encouraged. These reforms have been inspired by the need to tackle various problems that had arisen, such as the perceived harmful elements of societys preoccupation with academic achievement and the problematic behavior of young people. In this paper, the following issues are examined: (1) education policy and reform measures with regard to parent and community involvement in the childs education; (2) the state of parent and community involvement at the eve of the 20th century. 相似文献

Very few empirical studies have investigated programmes in which doctoral students act as peer facilitators in faculty writing groups. We report on the development of a centrally delivered doctoral student writing programme in which twenty student participants were mentored and provided with the resources to initiate their own faculty-based doctoral writing groups. ‘Legitimate peripheral participation’ was used as a conceptual lens to interpret the data collected during the establishment and evaluation of the programme. All student participants in the preparatory training course, which was developed in consultation with postgraduate students and research supervisors, went on to become doctoral writing peer facilitators of peer writing groups. Insights from seven of these showed how a well-structured and supportive programme harnessed the benefits of peer learning by bringing personal rewards to participants and building institutional capacity around doctoral research writing literacies. 相似文献

ABSTRACTStudies have found that Faculty–Student Interaction (FSI) has many positive benefits for students including academic support, professional development, mentoring, and career planning. Research-intensive universities exhibit the lowest levels of faculty–student interaction within higher education. This article utilises qualitative methods to explore faculty, student, and staff perceptions of faculty–student interactions, particularly those that take place out of the classroom, at a research-intensive public U.S. university. We identify social distance between faculty and students based on unequal status within a rigid, hierarchically-organised culture as a key barrier to FSI. We then discuss methods that some of the faculty in our study used to mitigate their social distance with students in an effort to increase FSI. 相似文献

Can the development, both clinical and managerial, of practitioners involved in healthcare be enriched by connecting action learning principles and practice with research on ‘tempered radicals’? Might such connection also assist the efforts of patients and their advocates to create more holistic approaches to patient care? This paper explores these questions with reference to a UK Department of Health project to improve renal services. The prime focus is the experience of a set of set advisers who ‘held the ring’ on the project, supporting the work of the sets and attempting to make sense of the emerging learning. 相似文献
