Description
Technical Field
The invention relates to the technical field of teaching management, in particular to a student score evaluation system in a mixed teaching environment.
Background
As one of supplementary means of "internet + education", online-offline hybrid teaching (OOBT) integrates the advantages of the traditional classroom teaching mode and the networked teaching mode, and draws wide attention in the teaching field of colleges and universities in China. The teaching mode is originally caused by an E-commerce transaction mode, is introduced into the training field to develop into hybrid learning, and is gradually formed in the teaching reform of colleges and universities. On the basis, the OOBT breaks through the restriction of the traditional offline teaching on time and place, realizes the integration of high-quality resources, realizes rich teaching resource sharing, simultaneously keeps the master and rhythm control of teachers on the classroom state in the traditional offline teaching, and continues and develops the stereoscopic impression, immersion and touch sense of classroom teaching.
Educators find that the open multi-OOBT will become the norm of teaching mode in colleges and universities in the future. However, how to evaluate the student performance in the OOBT mode becomes a problem that teachers and students pay more attention to at present. The OOBT score assessment has difficulty in assessing how reasonable the proportion is distributed: for example, the examination mode under the continuous line tends to excessively exaggerate the examination result of the scroll and neglects the examination in the process; secondly, the subjective judgment of any teacher will influence the ordinary performance of students, and the students' cadres, seats, front and back, etc. interfere with the judgment of teachers invisibly, so that the practical situation of students is difficult to be reflected comprehensively, objectively and fairly. Scientific and reasonable score evaluation is an index for checking acquisition of professional knowledge and learning ability of students and is also a basis for evaluating competition of awards, ranking, evaluation, graduation and the like. Performance assessment is therefore an effective means essential to maintaining fair competition.
The core of the performance evaluation is to calculate the weight of each evaluation index. Common weight calculation methods in education systems include expert scoring, analytic hierarchy process, cluster analysis, entropy method, and the like. The expert scoring method mainly depends on the experience of experts, and the calculation method is simple; the analytic hierarchy process needs less information and is strong in systematicness; the entropy method avoids the deviation of human factors; the clustering analysis method is concise and intuitive, but ignores the ambiguity of subjective decision makers in the evaluation system. It is worth mentioning that the fuzzy set method can eliminate the fuzzy uncertainty generated by evaluation, but cannot be used alone for evaluating the weight, so that a system capable of effectively evaluating the score of a student is urgently needed in the prior art.

Alpha reflects the steady or fluctuating state of preference of the teacher in assessing performance and can take any number between 0 and 1. When alpha is 0, the uncertainty is the largest, otherwise, the uncertainty is the smallest, and the evaluation decision is more stable; the risk tolerance lambda is the psychological state of the teacher when making a decision, and is highly pessimistic when lambda is 0, and is highly optimistic when lambda is not. Alpha and lambda are typically represented by five numbers 0.1, 0.3, 0.5, 0.7, 0.9 for different states.

The quantity index for measuring the inconsistency degree of the fuzzy judgment matrix is called as a Consistency Index (CI), and the parameters are set as follows:
in the formula, λmaxAnd n represents the dimension of the matrix, when CI is 0, the fuzzy judgment matrix is highly consistent, and the larger CI is, the more serious the inconsistency degree of the fuzzy judgment matrix is. The Consistency Ratio (CR) is defined as the ratio between the consistency index of the matrix to be evaluated and the consistency index of the random matrix. RI (n) is a random index which depends on the dimension of the matrix, as shown in the following table, if CR ≦ 0.1, the consistency of the matrix satisfies the condition, or notThe fuzzy decision matrix must be adjusted. As shown in table 8 below, table 8 is a random index of the random matrix.
