【摘要】 随着网络的兴起,尤其是Internet(因特网)的迅猛发展和应用普及,基于网络的教学成为人们越来越关心的话题。与此同时,相对传统的教学方式,探究教学日益显示其重要性。网络所提供的海量集成的信息资源、强大的信息加工工具以及良好的互动交流环境,使得基于网络的探究学习突破了课堂探究教学的局限性,在当今开放的教育环境下,显得尤为必要。 如何界定基于网络的探究教学,如何利用现有的网络资源网络技术开展网络探究教学,如何依据网络探究活动的标准设计探究活动,成为目前急需解决的问题。本文详细论述了网络探究教学的本质、特征、标准以及教学设计等问题,以加深对其正确的理解和认识。 在此基础上,本文重点探讨了在虚拟天文台(VO)环境下开展天文网络探究学习的优势及技术上的相关问题。天文学的特点、传统天文教育方式与学生认知发展的矛盾,需要我们认真的思考网络探究教学在改变现有状况中的作用。而虚拟天文台是近年来提出的一个新概念,其主要目标是通过计算机网络,实现海量、分布式、多波段天文数据的无缝融合和高效处理,发挥出天文数据库的全部科学价值。虽然现在web上已经可以存在大量真实的数据及图像等资源,但是,VO的出现使得数据查询处理更为方便和高效,为学生进行天文探究学习提供了良好的教育平台。 在如何利用VO开展探究教学方面,本文进行了尝试性的研究,从教师需要了解的获取发布资源、编写应用服务及设计探究活动三方面分别作了讨论,并结合相关的案例,进一步分析了利用VO开展探究教学的优势。更多还原

【Abstract】 With the appearance of network, especially the rapid development and popularization of the Internet, the web-based learning became a theme for which people cared more and more. Besides, relative to the conventional pedagogy, the inquiry-based teaching revealed its increasingly importance. The network provide us vast resources, powerful processing tools and convenient communication environment, which make the web-based inquiry teaching break through the limit of class-based inquiry teaching. Under the open educational environment, the web-based inquiry is necessary to us at present.What is the web-based inquiry teaching? How can we put the inquiry teaching into practice based on the web resources? How to design web-based inquiry activities according to the standards? These questions all need to be explained. This paper discusses the theories of the web-based inquiry teaching, such as the essentials, the characteristics, the standards and the design of inquiry activity, to improve our understanding of it.Then, the paper considers the advantages of carrying on the web-based inquiry teaching using Virtual Observatory (VO), and the relative technology. In view of the features of astronomy and the conflict between the traditional astronomy pedagogy and the student’s cognitive development, we think the web-based inquiry teaching is a good choice in today’s astronomy education. On the other hand, the concept of VO is put forward in the near years. The principal goal of VO is to integrate and utilize the worldwide major astronomical research resources transparently. Though a great deal of data and images have already existed on the web, VO facilitates the更多还原
