Design And Implementation Of Course Learning Management System Based On Knowledge Structure

The author taught the school is an art class secondary vocational schools,in the classroom teaching encounter the following questions: students can not own small test test their learning results,the teacher to change the volume of heavy tasks,unable to timely feedback on student examinations;It is difficult for students to collect and manage a large number of paper designs and score,which is not conducive to long-term custody and is not easy to display outstanding works of students.The learning ability of vocational students is generally poor,Knowledge needs to be repeated learning in order to digest,but vocational education focus on student vocational skills training,practical operating courses are more limited classroom teaching hours,the teacher can not repeat the presentation many times,unable to take into account the different receptivity of students,Of classroom teaching can not meet the learning needs of students.This paper studies the online learning system,especially the popular MOOC in recent years,analyzes the demand of the course learning management system in detail,designs a course learning management system based on the knowledge structure to provide the curriculum teaching to the teachers and students,Learning and curriculum management services.First of all,the system for the school curriculum,designed for each course of the tree structure of the knowledge structure navigation directory and curriculum learning resources,question banks,operations and so on,so that each function is based on knowledge structure to operate,The use of habits.Secondly,according to the teacher-oriented curriculum management,students focus on curriculum-oriented thinking of the design of the system functions,teachers and students to show the operation of some differences.Thirdly,in order to solve the problems such as online self-test,online examination,job management,resource management and so on,in order to solve the problems of teachers and students in course assessment,collecting and managing students’ hard-to-print hard work,MOOC compared to the focus on the function of student learning outcomes of the evaluation and management.Finally,this paper uses the SQL database management system to design the database structure,the data field,the primary key and the foreign key of the course learning management system,strictly control the redundancy of the database tables and fields,and improve the database efficiency and simplify the program complexity.After testing the function of this paper,all the functional modules can meet the needs of teachers and students.The use of course learning management system to solve the problems of classroom teaching effectively and realize the sharing and sharing of resources.Using the test tool Apache JMeter stress test the system,according to the size of the school teachers and students simulated the 2000 users at the same time using the system random access 7 pages,from the response time,stability and security of the three aspects of test system performance.From the test results,the system’s response speed,performance,stability,security is better,the overall performance to meet the needs.
