Personalized Collaborative Learning Research And Application Of Collaborative Learning System, Organization And Strategy

With the development of computer technology,information technology and network technology,the network education has been becoming a new way in the field of education. Computer supported collaborative learning(CSCL) based on Internet has become the hot point of research.To overcome the disadvantages of the existing Collaborative Learning System such as the application of learning organization and strategy,this paper has combined the Beijing Municipal Higher Education approved the teaching reform project " to create discrete mathematics teaching aids platforms,improve the quality of undergraduate teaching",researched and implemented the active,personalized organization and strategy of leaming in personalized collaborative learning system(PCLS),better reflected the main features of personalized collaborative learning.In this paper,the main research work and the results are as follows:1.To build a model of PCLS.First of all,it analyzed the collaborative learning system's strengths and weaknesses in teaching application,studied the relative theory of collaborative learning and CSCL,further combined collaborative learning with personality theory,and designed a personalized collaborative learning system model for "Discrete Mathematics" curriculum.2.To design a personalized organization and strategy of collaborative learning.This is the focus of the study,including the following three aspects:(1) Focusing on the design of grouping strategy based on the combination of genetic algorithm and K-means algorithm.According to the grouping principle of Collaborative learning, first of all,selecting K-means algorithm as the basic,secondly aiming at questions hard selected of the initial focal points for all kinds of classes,it combined genetic algorithm to optimize.With their organic combination,it achieved students' grouping.(2) To design strategies to generate study task.In this paper,the "Discrete Mathematics" curriculum knowledge points were divided,and organized in accordance with the pre-ordering relationship between them,and then the sequence of all knowledge points were formed by some rules.On this basis,combining of teachers' goals of teaching and learners' level of study,it designed a reasonable generate strategy for task.(3) To design Collaborative control strategy.In this paper,based on the requirements of collaborative learning,combined with the needs of the system's application,it studied the strategies in three aspects,including the recommendations of the objects consulted with by students,the identification of students role and the adjustment of study task,in order to form a complete and effective collaborative control strategy.3.Implementation of the personalized collaborative learning prototype system based on "Discrete Mathematics" curriculum.This paper analyzed the practical needs of the system,based on the J2EE platform and SSH framework,the use of the Web Service technology which can create distributed applications,allowed the system to have good flexibility,scalability and distribution advantages.
