Research On Re-evaluation Index System For Postgraduates Majoring In Discipline Teaching Based On Fuzzy Mathematics

Although the discipline teaching specialty master and the academic Master degree are at the same level,the training goal is different,the training specification each has the emphasis,therefore in the retest examination aspect is different.At present,there are some unreasonable weights,subjective arbitrariness and lack of quantitative standard in the double selection of postgraduate in Chinese subject teaching.It is the key to use scientific method to select the examination index and determine the reasonable weight.The process and result of subject teaching enrollment examination are closely related to people's thinking,while thinking has great fuzziness,so the fuzzy mathematics method is introduced into the second-round exam of subject teaching.According to the questionnaire analysis method of experts and the characteristics of students ' quality,combined with the quality onion model,the indexes of evaluation factors were expanded,and finally 25 alternative indexes were obtained.Because of the similarity degree of the index of the expert or quality model,the fuzzy cluster analysis is used to select the index.The first step is to select the standard data processing,and use the fuzzy clustering method to cluster the evaluation index of the subject teaching Master's second-round exam,select the similar index according to the related index,and finally selected 15 items of two grade index.To provide practical value for the construction of subject teaching postgraduate second-round index system.Fuzzy Mathematics method is more difficult to determine the attribute weight,this paper introduces the traditional method of weighting,summed up their advantages anddisadvantages,whether the subjective weighting method or objective weighting method in determining the weight can easily ignore the ambiguity of decision-makers.Many researchers realize that the determination of index weight is not only related to students,but also depends on the development of postgraduates.A method of determining the index weight of triangular fuzzy number is proposed.The fuzzy judgment matrix is mainly constructed,and the weighted algorithm of triangular fuzzy number is optimized.and combined with the data collected to analyze the weight of the evaluation index,get more reasonable weight.Finally,the practicability and operability of the weight are verified by an example.It provides a new idea for the examination of the subject teaching postgraduate.
