Application Research And System Design Of Online Learning In Cloud Computing Environment

With the rapid development of network technology and computer technology,online education has become an advanced teaching method in contemporary society.Correspondingly,online learning has also become a way for more and more learners to obtain information and improve their grades.At the same time,with the maturing of cloud computing technology,it becomes flexible and efficient,scalable and shareable,which provids new technical support for online learning.However,because of heavy school work,enormous study pressure and the dominance of traditional teaching mode in secondary schools,the current online learning is difficult to popularize especially among secondary school students.In terms of the traditional teaching platform,it lacks flexibility,teacher-student interaction and effective follow-up tools,which makes it impossible for online learning to be popular among middle school students.In view of the above problems,this paper will analyze the existing shortcomings of online learning for the purpose of practice,put forward views,and design and implement an online interactive learning system in the cloud computing environment.The main work of the dissertation is as follows:1.The characteristics of network teaching in cloud computing environment are analyzed.In aspects of teacher-student interaction,evaluation of learning effects and heterogeneous terminals access,this paper explores the application mode of online teaching.With construction of an online teaching application Model in cloud computing environment,it also explore online learning applications from some aspects of support services,effectiveness evaluation,resource sharing,information technology,teacher-student interaction,and sustainability.2.The design realizes an online learning platform in the cloud computing environment.The platform consists of seven modules,four of which,such as online course management,interactive teaching management,performance evaluation management and learning progress management,are application modules for online teaching.There are also three targeted system management modules,including servermanagement,community management and operation and maintenance management.It can be briefly summarized as "four + three" module design.3.Implement the system according to learners' learning needs and integrate teaching resources.At the same time,the platform is preliminarily evaluated by practical application.Teaching resources mainly involves Micro-Course Online Video of lecturers from high schools or open network courses.Finally,the application applicability of the platform is preliminarily evaluated by means of user feedback,data statistics and final evaluation.Research shows that online learning system based on cloud computing can accomplishe online on-demand learning,online troubleshooting,and tracking of learning outcomes through testing.In addition,it promotes learners' awareness and ability of self-learning and realizes aplication objective of the learner-oriented.This research realizes the real teaching instead of merely offering teaching resources by adopting the key technologies such as virtualization technology,asynchronous communication technology,mobile client technology and Hadoop system.There are three main innovations in this research:1.The application model of online courses under cloud computing environment was explored,and the module design of "four + three" was realized.2.The cloud note management system has been added to realize online note recording,document upload and edit functions.3.Real online answers have been achieved.Learners can upload pictures to ask questions.Teachers can answer in real time through voice and text,improving interaction.
