【摘要】 近年来,无线局域网技术得到了迅猛的发展,并且逐渐渗透到各个领域,其应用范围越来越广,教育也不可避免地受到这股“无线旋风”的影响。无线局域网技术在教育领域尤其是高等教育的全面应用将是大势所趋。如何把这项技术与现有的教育教学资源相整合,创建一种全新的教学环境和模式,改善和提高教学和学习的效果将成为教育技术研究的一个新课题。 目前,国内对无线局域网络在教育教学中应用的研究还不多,大多数还停留在为提倡推广无线技术在教育中应用而摇旗呐喊的理论阶段,少数一些研究也上升到了应用层次,但是却过于偏重其作为网络接入手段这一单一层面和作用。 无线局域网技术作为一种新的网络接入技术,它能够给教育带来的不仅仅是简单的网络接入。由于其组网灵活、无缆线约束等自身固有的优势,使得它能够为传统课堂教学在方法和形式上带来巨大的突破。本研究从传统课堂教学出发,通过分析现有课堂环境之优劣,同时结合建构主义学习理论,构建一种无线网络支持下多种交互模式相结合的无线教室环境及应用,并在此基础上对在无线教室环境下的教学和学习进行了尝试性的设计。 通过建立起高度交互的无线教室环境和应用,辅以适合的教学设计方案,能够改善传统教学中教师主导、学生消极被动、师生间缺乏交流和沟通的单一教学模式,借助先进的教学和学习理论,使教师和学习者积极参与到交互和协作中,从而有效激发学习者的思维,使他们在相互交流和理解的过程中得到知识的迅速内化和固化,完成认知结构的重新建构,最终获得有意义的知识学习。 本文主要研究了在传统教室环境下应用无线局域网技术构建高度交互的无线教室环境和应用,并对在该环境下进行教学进行了尝试性的教学设计。在研究过程采用了文献检索、系统设计、应用程序设计及实践应用等方法。 主要完成了如下工作: 1.文献检索 为了较科学地构建高度交互的无线教室系统,笔者查阅了大量国内外对无线技术应用的相关文献,尤其是与教学和学习密切结合的领域,如移动学习、无线学习等。一方面很好的了解了该领域目前在国内外的发展现状,另一方面通过学习和吸收先进的思想、方法和经验,保证了在设计上的科学性和前瞻性。更多还原

【Abstract】 Wireless LAN technology has been developed rapidly in the last few years and has been widely used in many areas. The education field has been impacted greatly by this Wireless Storm. It is obvious that the new technology will have great potential in our future education, especial in the Higher Education domain. Therefore, it will be a new research topic that how to integrate the new technology and the existing education resources to improve the teaching and learning effect, what kind of powerful new teaching and learning experiences are possible.As we known, the wireless LAN technology is a new form of network interface, it has some unique advances and features which can give tremendous changes in traditional teaching methods and models. This paper first analyses the benefits and shortcuts of the existing classroom environment, after that, we trying to integrate the new technology with the construction theory to build a highly interactive wireless classroom environment together with a set of application tools to facilitate the classroom interaction. Finally, we integrate the wireless classroom environment and its application platform with one of the pedagogical models-the Jigsaw Model to demonstrate how such highly interactive teaching and learning environment can best promote instructor’s teaching and students’ learning.In the traditional class, students will assume a posture of "civil attention" and passively receive while the instructor plays the role of "the sage on the stage" and actively deliver. The highly interactive wireless environment coupled with a compatible instructional design can greatly changed the deficiency in the traditional class .With the support of a set of interaction and collaboration tools, the instructor and students can easily carry out different type of learning and instruction activity, thus help to spark the students’ thinking, constantly change their cognitive structure, and further promote individual higher order cognitive development.The following research methods were used in our research:1. Literature SearchIn order to construct the wireless classroom environment scientifically, the author consulted plenty of literature about the application of wireless LAN technology,especially in the mobile learning and wireless learning domain, thus make this research preconscious.2. Program DesignA series of program tools and techniques were used in the building of application platform, such as PHP, Flash MX, ActionScript and MySQL. The application platform has the following function models: (1) Class Broadcasting: The instructor can easily broadcast their image and voice to distant learners with microphone and webcam through the internet. (2) Collaborative Knowledge Building: It is a set of tools to help learners carry out diverse collaborative learning activity. (3) Shared Whiteboard: It helps the instructor and learners to express their ideas and concepts by drawing schema. (4) Quiz: It helps the instructor to build quizzes quickly; the learners can take their quizzes on their digital learning devices and the feedback will be delivered instantly. (5) Poll: It can be used in some circumstance which helps both instructor and learners to make decisions.3. Instructional DesignFinally, this paper tries to explore the instructional design in the new classroom environment, which under the support of the wireless LAN and the set of application platform. We try to apply one of the traditional pedagogical models - the Jigsaw Model to the new environment to demonstrate how such highly interactive teaching and learning environment can best promote instructor’s teaching and student’s learning.The research in this paper is still in the exploring level. Due to the limitation of equipment, we have difficulties to put the whole design into real practice, and are not able to evaluate the new environment in real circumstance. There are still some problems need to be solved in our further research.更多还原
