Design And Implenmentation Of Comprehensive Quality Evaluation System For Students In Higher Vocational Colleges

The comprehensive quality evaluation(hereinafter named as CQE)on students of higher vocational colleges is one of the most significant part among the existing educational informationization.By applying the CQE,vocational college students can be automatically evaluated in a multi-faceted manner,including their external image,internal characters,knowledge accumulation,self-cultivation and psychological states and so forth.Thereafter,it's quite essential for vocational colleges and also other colleges to research and develop the specific CQE system on basis of actual situations of their own so as to provide with comprehensive,realistic,scientific and efficient evaluation criteria and methods for students,which in return can greatly improve students' qualities just as an old saying goes-“Sharpen your tool before achieve your work”.For colleges and teachers,developing the CQE system can greatly improve the colleges' management and teacher'work automation.For students,it provided with positive motivation to improve their personal qualities and teaching effects so as to ensure their employment abilities in the long term.This thesis,with the R&D of the CQE system set as the research background,carried out a systemized and comprehensive demand analysis by using the object-oriented approach on basis of practical investigation and analysis of the teaching situation of higher vocational colleges.Meanwhile,it designed and developed the CQE system by adopting the mainstream WEB2.0 technology and using the Yii2 framework of PHP programming language based on the status quo of the development team.Highlights of this thesis:(1)Established the CQE system targeted at the actual teaching situation of higher vocational college on basis of the research results of CQE of students both at home and abroad;(2)Carried out a full demand analysis of the development of the software system as per CQE systems of higher vocational colleges;established function modules for the system;conducted the feasibility study for developing the system;designed overall the system framework including corresponding use cases,database and workflow of the module.(3)Researched and developed the system function modules by using the technology related to the Yii2 framework;eventually completed and realized each function module.(4)Tested the software system by applying the Yii2 framework;troubleshot any problems discovered through the unit test and verification test on the framework;finally verified the performance and operating efficiency of the software system by means of stress testing.
