Preliminary Study On The Application Of Discriminant Model In Classroom Teaching Evaluation

Evaluation of classroom teaching is the teaching of core content and standardized management to improve the quality of teaching management an important part of modern education reform is one of the key issues. A reasonable evaluation index system and assessment of science education teaching evaluation methods have a positive role in promoting and guiding, not only conducive to national education policy and policy implementation, the implementation of educational laws and regulations, but also for the quality and structure of teachers the overall optimization.In previous studies of classroom teaching evaluation,on the basis of this evaluation of classroom teaching of mathematics in secondary schools, for example, attempts to explore a new kind of more objective and correct, a more simple method of classroom teaching evaluation. Previous related studies have not yet involved in the use of mathematical models, this paper will try to use mathematical models to determine the method of evaluation of classroom teaching. Through a series of exploration and qualitative and quantitative research, mainly conclude to the following conclusions:(1) In the index system, and with the mathematical model of the way, you can minimize the impact of subjective factors. Most previous studies of experts to set targets, and the use of mathematical models is to allow the data to set targets and evaluate the nature of the same class of data, data analysis tools with their comparative analysis, which found that the distinction between this type of data play a decisive role indicators. These indicators, the evaluation index system constitutes.(2) Given in the index weight, and with the mathematical model of the way, you can make it even more accurate and more scientific. Previous studies, using a simple scale for evaluation of classroom teaching, the weight given is mainly determined by virtue of human experience, in dealing with data, and a simple weighted average of these values results, as the final results of the evaluation. In fact, given the value of the index factors, strictly speaking, is not with the additive in nature. Therefore, this method is not scientific. In fuzzy set theory to classroom teaching evaluation is a method of evaluation of artificial intelligence, the use of rating criteria evaluation software to complete the assigned weights, although overcoming the drawbacks of a simple weighted average, but it is relatively difficult to operate.(3) In this paper, evaluation of classroom teaching in middle school mathematics class, for example,200 training samples selected for data analysis, discriminant function to establish four levels, and with 50 samples tested for stability and accuracy of the model back on behalf of the test results show that model has a certain accuracy and stability, can be used to complete the actual classroom teaching evaluation.Overally speaking, the mathematical model of the method not only to overcome the past, the subjective factors of classroom teaching, but also to overcome the drawbacks of a simple weighted average, and operation and are relatively easy to understand.
