Design And Implementation Of Online Learning System From The Perspective Of Personalized Information Service

The continuous progress of information technology and integration with the field of education promote the development of modern education,as well as the change of the learning style of the learners.After the emergence of theory and technology related to web 2.0 in the upsurge of new information technology,the online education platform such as MOOC has emerged,which adopted by various universities in the world.Some Internet giants also step on the outlet of online education,build up their own commercial cloud class study platform,expanding learners from college students to the public including workplace.In order to obtain a increased market shares,some pertinent measures have been put forward and try to make adjustments in the business operation mode,ultimately formed the situation that B2B2C,B2C,and several other type online learning platforms competing with each other.Under the good information environment supported by AI and other technology,online learning as one of the thinking styles in twenty-first century,has become a new trend of promoting learner's personalized learning and development in the area of "onternet plus",and also become a hot subject for scholars.In the first,this paper starting from the concept of personalized information service and related theoretical knowledge,expounded the general characteristics of personalized information service,summarized the three dimensions of personalized information service.In the next,described the current development of online learning in universities and the society,analyzed and compared the characteristics of all kinds of online learning systems at home and abroad.After that,discussed three design principles of online learning system from the perspective of personalized information service combining the status of online learning system,designed some functions of the system by the dimension of individualization of service mode,and developed a set of web-based online learning system which has some innovations in the mode of service with related tools under the certain development environment.In the end,this paper tested the system from the aspects of system performance and user experience,and summarized the test results.This paper studied online learning and relative system based on personalized information service,designed the online learning system from the dimension of personalized service mode,put forward AJAX based visualization module of learning progress built a precise search model based on knowledge points,designed an adaptive recommendation module based on collaborative filtering.The test results show that the online learning system designed from the perspective of personalized service mode has some improvements in functionality of learning progress tracking,learning resource retrieval,adaptive recommendation,improved user experience and user adhesiveness.
