The Design And Development Of Mobile Learning Environment Based On Knowledge Visualization

With the rapid development of intelligent mobile devices and the mobile communication technology, various mobile learning platform has been developed, which can let people make efficient use of fragmented time to study independently. Mobile learning has become an important way to acquire learning opportunities. However, the present mobile learning environment generally exists some weaknesses, such as scattered learning resources, lack of guidance of the learning behavior, hard to establish the system of knowledge’ structure. The new mobile learning platform which can improve the learning effect has become research hotspot in mobile learning. In this paper, a new type of mobile learning environment is designed to provide effective solutions for the present learning environment flaws.Based on relevant literature and the analysis of current mobile learning platform, this paper constructs the mobile learning environment by using the knowledge visualization. Put forward "small class" mobile learning environment for knowledge representation and mobile learning, and use the Web client development technology to achieve it. The following work is accomplished:Firstly, the theoretical background for mobile learning environment based on knowledge visualization is analyzed and summarized, in-depth study the learning theo ry which will be used in the design of the learning environment; based on the survey of domestic and overseas research status of knowledge visualization and mobile learning, analyze the learner model and related learning partner recommendation technology.In the research, I design the four modules of the "small class", which include knowledge visualization,learning resources,learning information and recommendation system; use the navigation map of the knowledge to promote students’ understanding of the curriculum framework; use visualization tool to promote the reconstruction, memory and application of the knowledge. Based on the collaborative filtering and content-based recommendation algorithm, design the personalized friends recommendation module."Small class" learning environment design two kinds of learning partner push methods:user similarity learning partners push and learning partner push based on academic information.Finally, the learning environment is tested in teaching experiments.The main work of this paper is summarized and the future work is prospected.
