The Design And Implementation Of A Secondary Vocational School Teaching Evaluation System Based On The B/S Framework

Teaching evaluation is an evaluation of the process and results of teaching activities.It is an indispensable part of the teaching process.It has a certain guiding effect on teaching work and is the main means to evaluate the performance of teaching work.At present,the teaching evaluation of our school still adopts the traditional teaching evaluation method.First,the"student evaluation form" is issued to the students at the end of the semester,and the evaluation information of the students on the teaching quality of the teachers is collected.Second,the supervisors are arranged to randomly attend classes and fill in the classroom.Teaching evaluation form".This evaluation process obviously lags behind the development needs of today's technology information age,and adds a lot of unnecessary work.Based on this,this paper designs and develops a teaching evaluation system based on B/S architecture.The main work of this paper is addressed as follows:(1)Read a large number of domestic and foreign references,and compare and analyze the current mainstream design concepts and implementation methods.Using the Microsoft Visual Studio 2010 development platform and Microsoft SQL Server 2012 database technology,the design is based on the B/S architecture.(2)A comprehensive analysis of the teaching evaluation system,including the overall demand,functional requirements and non-functional requirements,and then using the data obtained from the analysis to model,put forward several principles of the system design,and set up System framework diagram.The system framework diagram consists of five modules and gives a functional analysis of the major functional modules.(3)One of the focuses of this thesis is the generation and export of crystal reports in the statistical analysis module.By using data warehouse technology,On-Line Analytical Processing(OLAP)is used to store data from multiple angles.Data analysis with teacher evaluation results provides a reference for teaching management workers' decision-making.At the same time,the E-R diagram is given,and the data table,latitude table and fact table are designed,and the relationship between each table in the SQL Server 2012 database is given.(4)Using decision tree algorithm to analyze the data of teaching evaluation.In order to improve the objectivity and accuracy of the algorithm,an improved decision tree classification algorithm is proposed and applied to the teaching evaluation system.The improved decision tree algorithm is used to model,and finally the relationship between teacher title,student evaluation result,peer evaluation result and self-evaluation result is obtained.Finally,five administrator users,30 teacher users,and about 115 student users were opened to download and upload multiple browsers,and the teaching evaluation system was tested from four aspects:functional test,performance test,security test and aggressive test.Tests are carried out,and the test indicators meet the established requirements of the system and can meet the requirements of teaching evaluation work.
