【摘要】 远程教学媒体的发展经历了三代,即印刷技术、视听技术和计算机通信技术,这些多样化的媒体本身并没有绝对的优劣,也各能发挥不同效力或效益;在教学媒体的选用上,除了认真考虑媒体、教学及情境三方面因素外,为了发挥媒体教学功能并增加使用的灵活性,我们还可以综合运用多种媒体于教学中。媒体运用在教学上必须有系统化的教学设计,这些设计步骤具体化的建构,称为教学设计模式。一般来说,大部分的教学设计模式都包括分析、设计、开发、应用以及评价五个阶段,每个阶段又包含不同的具体元素。虽然这些模式都可以通用在不同媒体的制作上,不过有些模式会特别适用在某类媒体的开发上,我们必须依具体的课程情境需求,选择并改编适用的教学设计模式。展望未来,远程教学将成为教育发展的主流,而网络更会成为媒体中的宠儿。随着信息技术功能的发展,并予以适当的教学设计,我们预期网络教学将建造一个“无人不可学、无时不可学、无处不可学”的学习化社会。更多还原

【Abstract】 There have been three generations of distance learning media: print, audio-visual and computer-based. Each has its strengths and weaknesses and can be pedagogically effective if the context of a school and the teaching strategies of its teachers are taken into consideration. With these media, distance learning can be delivered to a large number of students while removing the restrictions of time and space. Learning materials can be adapted for students with different perceptual preferences and interests, and quality and cost-effectiveness can be achieved. To better utilize the strengths and flexibility of different media, teachers can integrate a wide range of media in the learning and teaching process. However, the utilization and integration of different media must be based on systematic planning, which takes the form of a planning model typically of five phases: analysis, design, development, application and evaluation. While different versions of the model can be applied to the production of different media, some versions are more suitable to a particular kind of media. The version of the planning model to be selected should be modified with reference to programme/course requirements. In the future, distance learning will be the mainstream of education and the Internet themost important medium. With the rapid development of information technology and with appropriate planning, online learning will bring about a learning society in which everyone will be able to study anytime, anywhere.更多还原
