A Study On The Design And Implementation Of Laboratory Performance Evaluation System In Higher Vocational Colleges

With the continuous development of China's higher vocational education,higher vocational colleges has accounted for half of the vocational education in our country.Meanwhile,laboratory construction plays an important role in the development of higher vocational education.How to carry out the laboratory construction reasonably,how to improve the utilization ratio of the laboratory,and how to make full use of the laboratory in the experimental teaching are significant for the sustainable development of higher vocational colleges.The laboratory performance evaluation of higher vocational colleges can make a comprehensive evaluation to the laboratory,and it can provide the advantages and disadvantages of each laboratory in the teaching of the college.As the fixed assets of the higher vocational colleges,the author has been involved in the performance assessment of the college laboratory since 2007,with a large number of original assessment data,and a great deal of experience.On the basis of the full study of the domestic and foreign laboratory performance evaluation,this paper attempts to design and develop the laboratory performance evaluation system of higher vocational colleges,the evaluation model is verified by the test of the system.This system uses B/S structure,and the background database uses Server SQL 2012,ASP.NET technology and C#language to carry on the system development.The third chapter analyzes the system function from the user's point of view,according to the user's roles.And the main function of the system is divided into user login function,performance assessment administrator,laboratory full-time administrator function and judge function.In the fourth chapter,the function design of the whole system is presented,and the core function of the system is to realize the automatic evaluation,and the evaluation model directly determines the quality of the system.The author tries to establish the evaluation model of laboratory performance evaluation in higher vocational colleges,and the establishment of the evaluation index and the evaluation index of the performance evaluation index and the author's work.With the use of neural network technology to the past performance assessment data analysis and training,three layers of BP neural network evaluation model are set up after a large number of experiments.It also get s the relevant neural network evaluation parameters,and verifies the reliability of the evaluation model.In the fifth chapter,the main function of the system is given,the method and the operation interface are presented.The system is tested and the availability of the system is verified.Due to the limited time and competence,the whole system has yet to be further improved.The conclusion of this paper gives some suggestions to further improve.
