计算机支持的远程协作学习的理论、环境及技术

远程教育若想持续发展和生存 ,其关键是解决好教学的规模和质量问题 .目前的远程教学中主要依赖的信息共享 ,个体学习 ,有限交互的模式已经不能满足学习者对学习质量越来越高的期望 .本文认为 ,导致学习效果不佳的原因是由于网络环境下学习者之间相互隔离 ,缺少课堂学习的互动互助效果 .因此在远程学习系统中提供多种方式的交互手段 ,促进协作学习 ,是提高学习质量的有效途径 .为此 ,本文讨论了计算机支持的远程协作学习中有关的理论和环境要求 ,提出了基于信息资源重构 ,可操作浏览器以及 XML 统一数据类型协议等技术的解决方案

Computer-aided Distance Collaborative Learning Theory Environment and Technology

For distance learning, its survival and continuity development depends on its scale and quality of learning. In most of currently used distance education platforms, the learning mode are usually information sharing, individual learning with some limited interaction which can not meet the higher and higher expectation for learning quality coming from students. We argue here that in the circumstance of distance learning, students are separated individual, the lack of the mutual cooperation and mutual aiding can not provide the expected result as in real class. The measure to improve the situation is to enhance the collaborative learning ability in distance learning platform. This paper discusses the issue about the theory and environment of distance collaborative learning, in which the key techniques points of reconstructed information, manipulatable browser and uniform data definition protocol based XML are detailed.
