Design And Implementation Of Online Education Platform For K12 Users

With the increasing concept of the Internet +,under the premise of requiring the sharing of educational resources between the towns and the countryside,the education field has launched a non-commercial online education platform in due course.The combination of the Internet and education should be a matter of course.While the country is vigorously developing the Internet,it focuses on test-oriented education and innovative education.Therefore,"Internet + education"came into being."Internet +education"will have a huge and indelible impact on traditional education,which has changed the problem of unequal educational resources between urban and rural areas to a certain extent,and has further promoted the comprehensive reform of Chinese education.The topic of this thesis comes from the actual project of the author's internship company.The project name is"Design and Implementation of Online Education Platform for K12 Users".The actual R&D projects involved during the period.The main business modules of the project are divided into four modules:basic information module,teaching management module,operation management module and platform portal module.The basic information module completes the functions of role management,user management,student management,and category management,and realizes business functions such as granting rights to system users,viewing student details,and classifying operations;The teaching management module completes the course management and lecturer management functions,and realizes the creation and adjustment of course details and catalogues,the creation of lecturers and the function of labeling business;The operation management module completes the order management and the course redemption card management function,realizes the business operation of the order inquiry and the course redemption card,and the course redemption card business function can be used for the user of the platform to pull new and promote;The platform portal module completes the student user learning course and the business function of the lecturer's online live broadcast and correction.In this paper,the project requirements are deeply analyzed.Through the system summary design and further detailed design,the specific planning of each module of the system is completed.The class and its interface design are involved.The code is implemented according to the existing content,and finally the system function acceptance and online preparation are carried out.The project is built on the ASP.NET MVC enterprise-level development framework,using ADO.NET technology to interact with data programs,and calling specific classes and methods when interacting with data sources(databases,text files,Excel tables,or XML files).No need to interact with the database frequently to improve system performance.The data storage is realized by SQL Server2012 Enterprise Edition.The application is based on the learning interest modeling collaborative filtering algorithm.The recommended recommendation model is obtained by calculating the recommendation model through the similarity between the courses and the user learning interest degree,so as to improve the interest of the learners in the platform K12 stage.The online education platform for K12 users passed the system test and put into normal use in February 2019.The existing user base exceeds 5,700,and the daily PV reaches the highest level of 1000 or more.The servers carrying data and course resources are running stably.Ensure the learning experience of platform users.The platform provides a high-quality service experience for K12 users who need an online education business.At the same time,online education platforms for K12 users are constantly optimizing their iterations.
