Design And Implementation Of Micro-course Mobile Learning System Based On IOS Platform

With the effectively promote and positive development of educational informatization,because of its short and pithy,has abundant resources and the teaching topic is distinctive,micro-course has attracted more and more researchers to pay attention to it,micro-course expands the scope of learning space,makes the learning ways more flexible.Micro-course video learning systems in the foreign countries take the TED-ed educational channel,Khan Academy and Coursera as representative,in the domestic take the China Micro-course Network and Science Newtork as the representative,those websites provide a large amount of micro-eourse resources for learners,and provide convenience for user online learning activities,however,those systems aren't enough to take into account the needs of learners'mobile learning,and the mobile learning systems are relatively few,most of the existing mobile learning systems are designed according to the network video websites,some systems are not devefoped in conjunction with the characteristics of mobile intelligence devices,and doesn't provide vkieo resource recommendation service for users.Based on the theories of mobile learning,mastery of learning and constructivism learning,this paper combines the recommended technology with the micro-course mobile learning system to study the design and implementation of the iOS based micro-course mobile leaming system,which could promote the student's learning efficiency and the teaching quality.The main goals of this paper are to provide micro-course video learning and recommendation services,save users time to find resources,give full play to the utilization value of high-quality micro-eourse resources,according to the goals to design and development of micro-course mobile learning system which based on iOS platform,the main research works include the following aspects:Firstly,designed the iOS platform based micro-course mobfle learning system,which includes the functions design of micro-course mobile learning system and micro-course resources management system.The main functions of miro-course resources management system are micro-course resources management and publishing and users nanagement;the main funtions of micro-course mobile learning system are the micro-course video play,micro-course video search,micro-course video recommendation and so on.Secondly,this paper studies two kinds of micro-course video recommendation methods,one is based on the played and collected times of the micro-course video in the background system;the other is based on micro-course video labels to recommended,by calculating the TF-IDF value of the tag data as the weight of the tag,the similarity between the micro-course video is calculated according to the label weight,thus conpleted the recommendation.Thirdly,according to the function modules design,completed the micro-eourse mobile learning system based on iOS platform,including micro-course video playing,micro-course video searching,micro-course video recommending and users registering and fogjn of the client,and micro-course video management and publishing and users management and other functions of the server.
