Wiki在大学英语写作教学中的应用与实践 总被引:2,自引:0,他引:2
Wiki作为一种面向社群的协作式写作系统越来越受到教育工作者的关注,其对大学英语写作教学改革也有着直接的启示.wiki的开放性和协作性有效地弥补了传统英语写作教学中对作文阅读、反馈与修改等提高性措施方面关注不够的缺陷,实践证明,Wiki与英语写作教学相结合,可以充分发挥读、写、改间的交互性、参与性与合作性,对培养英语的写作能力优势明显.因此本文针对当前大学英语写作教学中存在的问题,提出了Wiki在英语写作教学中的应用模式,并进行了实践教学的总结. 相似文献

Computers are increasingly a part of preschooler’s lives. The purpose of the present paper was to discuss research avenues
employing computers as a learning tool and to analyse the results obtained by this method at the preschoolers’ learning level.
Specifically this research was to determine if computer assisted instruction (CAI) was a useful tool to enhance cognitive,
emotional, linguistic, and literacy skills in preschool children. CAI programmes may never replace the book and the blackboard
but one should be aware that they were more accessible by young children, who learn better with pictures and sounds, and the
proper use of appropriate programmes could make a considerable difference. 相似文献

This paper aims to stress the potential use of executive support systems (ESS) in the formulation of university objectives and strategies. A strategic planning methodology based on different university experiences is proposed, along with an ESS that we have designed and developed to support the strategic process. We present the methodology and show how to put it into practice by using our application. Finally, we discuss some results obtained at the University of Las Palmas de Gran Canaria, as well as the major obstacles and resistance raised both to the strategic planning and to the computerization of the process 相似文献

This paper introduces a new way of evaluating instructional strategies by using computers. Two basic theories, instructivism and constructivism, are discussed and critically evaluated in terms of their effectiveness in conceptual learning. Despite the current popularity of constructivism, the radical form of it is criticized in this paper. The advantages and limitations of these two approaches, especially the radical forms of constructivism, are outlined. After borrowing some ideas from other effective conceptual change models, an integrative model for conceptual learning (the Inventive Model) is introduced. Two versions of multimedia physics software are developed by the authors. The first version is based on the Inventive Model and the second version based on a radical constructivist model. The effectiveness of the Inventive Model was compared with the radical constructivist approach and conventional science instruction. Students' log files were analyzed to investigate the nature and the processes of the conceptual change. A conceptual test and a knowledge test were used to compare the groups. The quantitative results showed the superiority of the Inventive Model over the other models in conceptual learning and the superiority of conventional instruction in learning the basic knowledge. The qualitative analysis showed that only the Inventive Model lead to coherent conceptual learning. It was concluded that the process of conceptual change is gradual and continuous. Analysis of students' log files revealed no moments of dramatic change in students' conceptions. 相似文献
