Design And Implementation Of Optional Class Teaching Management System Based On 3+3 New College Entrance Examination Mode

In recent years,reform of college entrance examination has attracted much attention.In September 2014,the State Council issued On Implementation Opinions on Deepening the Reform of Examination and Enrollment System,in which some points were clearly proposed,including launching comprehensive reform experimental unit of college entrance examination,reform of examination subjects setting and examinee admission mechanism and promoting the development with personality in an all-around way.At present,there have been 30 provinces,municipalities and autonomous regions that issued college entrance examination reform scheme.Wherein,reform of admission batches and subjects setting are emphasis and cancellation of departmental system has been the trend.In June 2016,Shandong Provincial Department of Education issued Implementation Scheme of Regular Senior Secondary School Academic Proficiency Test in Shandong Province and Implementation Measures of Regular Senior Secondary School Students Comprehensive Quality Assessment in Shandong Province."3+3" college entrance examination mode has been implemented since 2017 when the high school freshmen were admitted in fall semester.Under the above background,it is extremely urgent for the senior high schools of various provinces and cities to implement optional class teaching management system based on 3+3 new college entrance examination mode.This system can help schools to learn more precisely about the course selection and hobbies and interests of students with informatization means regardless of the complicated optional class teaching management process;It can arrange class selection reasonably according to the faculty of schools;It can also help the teaching supervision for schools,feedback teaching information timely and gather and deal with the advice from teachers and students timely,which can promote the school management.Firstly,this article discusses the background meaning of optional class teaching management system based on 3+3 new college entrance examination mode.It elaborates the research status at home and abroad through research analysis and proposes to solve the problems faced by 3+3 optional class teaching system.All these main problems are described in detail in this article with demand analysis,preliminary design,detailed design and implementation and testing.Then,demand analysis is carried out for optional class teaching management system based on 3+3 new college entrance examination mode.The object-oriented UML modeling approach is applied in demand analysis.Multiple angles including courses selection,class grouping and course scheduling are covered and analyzed with cases.Then,based on the analysis of demand cases and operation flow,a complete solution is proposed directing at the demand problems about optional class teaching.And the final demand range is determined as regards functional demand and non-functional demand.Besides,on the basis of demand analysis,system preliminary design is carried out.According to the system demand,objective and principle of the system preliminary design are put forward.It is designed in the aspect of physical framework and logic framework respectively.The object-oriented MVC framework design idea and B/S framework are applied to achieve whole business functional framework in technical framework.The description method of data flow diagram is applied to express functional procedure demand in functional framework.Again,optional class teaching management system based on 3+3 new college entrance examination mode is designed in detail.Descriptions cover designs of all modules involved in preliminary design.In system modeling design,static modeling and dynamic modeling are applied,establishing system class diagram,phase diagram,sequence diagram,E-R diagram and other multiple-dimension system models,Operational modules including courses selection,optional class teaching and course scheduling are put emphasis on to carry out detailed design and data structure design.Then,through preliminary design and detailed design,view presentation of prototype design and ensemble is conducted in the aspect of system implementation.Implementation idea on optional class teaching and course scheduling and smart course scheduling algorithm are proposed in the modules of core courses selection,optional class and course scheduling.In the aspect of system testing,system testing environment and testing method are determined.Black-box testing method is applied to use different cases directing at different schemes of courses selection and optional classes.Testing objective and expected effect are determined based on the input/output data testing results.Finally,this article makes a simple introduction about the application prospect of optional class teaching management system based on 3+3 new college entrance examination mode and also makes a planning description about the follow-up plan for the gradual improvement of the system.In conclusion,this article,based on 3+3 new college entrance examination optional class teaching management mode,conducts preliminary design and detailed design with complete demand research and detailed demand analysis.Finally,it achieves optional class teaching management system based on 3+3 new college entrance examination mode and verifies the feasibility of system implementation.This article also makes a brief analysis about the future modification and the planning development for the system,which provides more development proposals for improving and upgrading the system.
