摘要
当今的社会是一个信息化社会。信息技术已渗透到生活中的各个领域,并为学习提供了更为广阔的发展空间,所带来的数字化的生存环境对我们的学习内容和学习方式提出了全新的要求和挑战。网络学习在信息化时代中孕育而生,并已渗透到教育领域的各个方面,使得在虚拟化的学习环境中运用网络化的教学手段开展交互式学习成为现实。虚拟学习社区是依据社会建构主义学习理论,以计算机和网络技术为依托实现在线学习的虚拟社区平台。在虚拟学习社区中,学习者可以像在现实生活中一样进行学习活动,实现在线讨论、交流和学习。然而,基于传统网络学习的虚拟学习社区有很大的局限性,它不能随时随地实现交流与学习。伴随着全球范围的无线技术和移动通信技术的快速发展,移动学习作为一种新型的学习方式应运而生。移动学习是利用无线移动通信技术,通过手机、Pocket Pc、PDA等移动终端设备随时随地获取学习信息、学习资源和学习服务的一种学习方式。基于移动学习的虚拟学习社区的实现,把人们从学习时间和空间的限制中彻底解放出来,加强学习者之间的交流,激发学习者的参与性、主动性和积极性,促进远程教学中的协作学习,极大提高学习效率,满足终身学习的需求。
本文主要从理论和实践两个方面对移动学习系统进行探讨。在理论方面,参考大量国内外文献,分析总结国内外在移动学习这一领域的研究现状;对移动虚拟学习社区进行了界定;探讨了移动虚拟学习社区的理论基础和特点;提出了移动虚拟学习社区的构建原则及模型。在实践方面,以移动虚拟学习社区理论做指导,运用Windows Mobile移动开发技术,尝试设计与开发了一个基于Pocket PC以“学英语,迎奥运”为主题的移动虚拟学习社区案例。在论文的最后,总结了本研究的成果和不足,展望了后续的可能研究方向。
Today's society is an information society. Information technology has penetrated into all fields of our life, providing a more broad space for learning. The digital living environment puts forward the completely new challenge and request to our learning content and method .Information age has boosted the birth of the E-learning which has infiltrated into all aspects of education field and made the interactive learning become a reality using network teaching methods in the virtual learning environment. Virtual learning community is a virtual community online learning platform based on the social constructivist learning theory computer and network technology. In the virtual learning communities, learners can study, discuss online and exchange ideas like in real life. However, virtual learning community based on the traditional learning network has many limitations, which can not be achieved anytime, anywhere to learn and exchange ideas. The rapid development of wireless technology and mobile information technology have greatly boosted the birth of mobile learning. Mobile learning(M-learning) enables free access to learning information, resources and service with the utilization of mobile information net work and device (cell phone, Pocket PC, PDA .etc). The realization of mobile virtual learning community has liberated completely learners from learning limitations of time and space, and strengthened the exchanges between the learners and stimulated participation, initiative, enthusiasm of learners. It can also promote collaboration in the long-distance teaching and improve the efficiency of learning to meet the needs of lifelong learning.
This thesis deals with issues related to mobile learning from theory and application. In theory , based on lots of literatures, this paper analyses and summarizes the research status of M-learning, and defines the mobile virtual learning community and discusses its theoretical basis and characteristics , and proposes its construction principle and a model. In practice, it tries to design and develop a mobile virtual learning community case of a Pocket PC whose subject is "learning English to welcome Olympics", with the theory of mobile virtual learning community and the windows mobile application technology. Productions and the shortcomings of this research are summarized in the end of this thesis; at the same time, the further research direction is also prospected.
