The Combination Of Student Performance Evaluation Model Based On DEA Research

Student assessment plays an important role in the whole teaching activity, it consists of many elements, and performance evaluation is a key index in the evaluation of students. So it is necessary to research on evaluation model of the grade. Usually use average to evaluation result, average score reflects the basic conditions of students remember to static performance. This method use is very wide is one-sided, and thus cannot effectively reflect the students learning state in a certain period of time.This article selects a school of 357 students as the research object, to a more objective evaluation of the students in a certain period of time learning the reflect students was developed for the analysis of student achievement evaluation model the amount of effort for the dynamic performance, MATLAB dynamic performance of every student can be obtained. If only according to dynamic performance evaluation of student learning, can lead to many students of opportunistic and make the result of evaluation. So to comprehensive static performance and dynamic performance, and combining with experience gives the calculation model of the grade Overall =0.475 * static performance +0.525*dynamic performance one of them. The q can are many kinds of methods, such as expert scoring method, analytic hierarchy process,factor analysis, multiple linear regression, etc., each method has its own advantages and disadvantages. Combined with the actual situation of this paper, the choice to improve the expert scoring method is finalized. Get an objective evaluation model of student mathematics study condition:. Into the data with statistics software to calculate the total grade of each student, you can get more reasonable evaluation of students learning situation.
