A flexible framework for online collaborative learning     

Petrea Redmond  Jennifer V. Lock   《The Internet and Higher Education》2006,9(4):267-276

This paper presents a framework for online collaborative learning, also known as telecollaboration. At the centre of this flexible framework are online collaborative educational experiences where knowledge creation and knowledge in action are the nexus of social, teaching and cognitive presence based on the Community of Inquiry model of Garrison, Anderson and Archers [Garrison, D.R., Anderson, T., and Archer, W. (1999). Critical thinking in a text-based environment: Computer conferencing in higher education. Internet and Higher Education, 2(2–3), 87–105]. The framework provided should guide educators as they design, develop and implement authentic educational experiences within local, national or international settings in partnership with other educational stakeholders.  相似文献   

基于智能代理的混合学习模式的设计     

李晓  吴郑红 《广东广播电视大学学报》2005,14(1):32-35

网络化学习已被越来越多的人接受和认可，但目前能很好的实现网络化学习的系统较少。本文引入智能代理技术，构建了集教学代理、学习者代理等多个代理于一体的网络学习应用模型，并强调了自主学习与协作学习之间相辅相承的关系，从而实现了自主学习、协作学习有机结合的混合学习模式。  相似文献   

Beginning readers' use of talking books: styles of working     

Clare Wood  Karen Littleton  Pav Chera 《Literacy》2005,39(3):135-141

This paper examines young children's working styles when they are engaged with a peer on a computer‐based reading task. Two types of pairing were investigated: (i) ‘Equal’ pairs, where the children were of equal reading attainment and (ii) ‘Unequal pairs’, where there was a disparity between the children's reading attainment. The results suggest that the children's reading attainment and/or their gender may be more significant factors in determining the nature of children's collaborative activity than pair type. The implications of these results for practitioners who wish to use talking books as a classroom resource are discussed.  相似文献   

‘Out of the Box’ leadership: action research towards school improvement     

Yiasemina Karagiorgi  Thekla Afantiti-Lamprianou  Vassiliki Alexandrou-Leonidou  Marianna Karamanou  Loizos Symeou 《Educational Action Research》2018,26(2):239-257

The contribution of Action Research (AR) to school improvement is well-documented. This study records the accounts of two primary school leaders, involved in AR projects that focused on the development of students’ oral communication skills. Drawing data from diaries with fieldnotes and systematic reflections, the study presents leaders’ experiences, as they translated feedback into modifications and redefinitions to bring about change. Despite difficulties encountered, the leaders acknowledged the value of collaborative school-based enquiry for teachers, students and themselves, mainly reflecting notions of catalytic and democratic validity. The paper highlights that AR as a tool for individual and school improvement, can enhance understandings of school performance and empower participants to focus on school outcomes in an educational context that does not implement accountability measures. AR can certainly help principals in Cyprus reconceptualise and rediscover their pedagogical role as instructional leaders to improve teaching and learning. Yet, to address outcome and process validity, the paper argues about the need for evaluative tools.  相似文献   

阈能的初等物理求法探讨     

冯喜忠 《襄樊职业技术学院学报》2004,3(5):18-20

可使吸能核反应发生的入射粒子的最小动能称为阈能。在核物理学里，求阈能一般用坐标变换的方法。遵循核反应中的电荷守恒、质量守恒、能量守恒、动量守恒，用初等物理的方法也可求解阈能，并适用与各种不同的碰撞类型。中学生可以利用这种方法计算核反应的阈能问题。  相似文献

Ordinary Least Squares and Quantile Regression: An Inquiry-Based Learning Approach to a Comparison of Regression Methods     

James E. Helmreich  K. Peter Krog 《PRIMUS》2018,28(3):206-222

We present a short, inquiry-based learning course on concepts and methods underlying ordinary least squares (OLS), least absolute deviation (LAD), and quantile regression (QR). Students investigate squared, absolute, and weighted absolute distance functions (metrics) as location measures. Using differential calculus and properties of convex functions, students discover the sample mean, median, and pth quantile by minimizing sums of distances. Students use these metrics to define loss functions for OLS, LAD, and QR, and explore methods to minimize them. We discuss classroom experiences over two semesters. Classroom activities, Maple worksheets, and R demonstration code are available at a companion website.  相似文献   

Enhancing Elementary Science Teachers’ Knowledge of Teaching: The Case of Designing and Implementing an Instructional Unit     

Jing-Ru?WangEmail author 《International Journal of Science and Mathematics Education》2004,2(4):455-476

This article provides a model for the professional development of elementary science teachers. The model focused on integrating different domains of knowledge into science teaching, including the knowledge of the science curriculum, especially scientific inquiry, teachers knowledge, and students knowledge. The two case studies in this article revealed that the teachers construct their knowledge in a social context. The constant reflections on the experiences helped them to generate alternative teaching approaches. The findings suggest that the model of the project had two functions. First, it provides a useful strategy to help science teachers to bridge the gap between theories of teaching and their own teaching practices. Second, it provides a social learning environment for learning how to teach science.  相似文献

美国基础科学教育改革及其主要特点--兼谈加强我国科学教育研究     

丁邦平  罗星凯 《首都师范大学学报(社会科学版)》2005,33(4):98-103

美国20世纪80年代中期以来开展的新一轮基础科学教育改革，是60年代科学教育改革的继续和深化。其基本特点蕴含着值得我国科学教育改革借鉴的丰富经验，如科学教育改革得到全社会的支持，尤其是科学界和企业界的大力支持；科学课程改革具有系统性和配套措施；科学教育改革高度重视科学探究和科学教育的普及；尤其值得我们重视的是，美国科学教育改革有大量的科学教育理论研究的支持。  相似文献
