Mobile Learning Environment, Learning Resources Described Research

The rapid development of mobile communication technology and the popularization of mobile learning terminal equipment, have created very good conditions for the development of mobile learning. Strong demand for lifelong learning, also have mobile learning showed a strong momentum of development, the application of space to develop more and more widely.Mobile learning includes mobile learning platform, mobile learning resources and mobile learning mode, which mobile learning resources is very important for the successful development of mobile learning. At present, there are still some problems in the construction of mobile learning resources. The one hand, the prevalence of mobile learning a wide variety of resources, dispersed disorderly; the other hand, mobile learning terminal equipment is very varied and complex, there are many differences between their function and the support of the operating system, resulting in the difficulty of each device support resources format conversion and portability sent; Then on the one hand, different developers design out of the mobile learning platform in function, system structure is also different, cross-platform and interoperability is not easy to achieve. The existence of these problems will certainly affect the development of mobile learning. The establishment of mobile learning resources description standard provides a standard for uniform resource format, resources can used between cross-platform and cross-terminal, reducing the frequency of duplication of resources development, and greatly improve resource sharing and utilization ratio.Mobility of mobile learning, the fragmentation of study time, the pieces of the mobile learning content put forward new demands for mobile learning resources. This paper mainly focus on mobile learning resources description research in the mobile learning environment, explore to how more accurately described mobile learning resources, also consider describe specifications and interoperability. Firstly, in reading the extensive literature on the basis of mobile learning, mobile learning devices and mobile learning resources, the platform, analysis the feasibility and the necessity of the mobile learning resource description, and put forward the principle of mobile learning resource description; and then learn from the current at home and abroad more mature standard of learning resources, combined with mobile learning to their own characteristics, try to set up the basic model of mobile learning resource description, define and explicate the elements of the mobile learning resource description; Finally, choosing a mobile learning resource fragment, combined with XML, a mobile learning resource description instance is given in accordance with the description of the design of standards, to verify the feasibility of the standard.
