摘　　要：通过精准教学以促进学生个性化成长是教育理想和国家政策的不懈追求.高校教师是实施精准教学的“基”,现有关于其教学能力的评价体系中普遍存在概念不清和多采用主观构建评价指标的问题.为此,开展了基于BP神经网络的高校教师精准教学能力评价模型研究.首先,以理论研究为基础,对精准教学能力进行等级划分并构建评价指标框架,运用层级分析法建立指标权重;其次,利用BP神经网络智能学习的特性,以不同数据类型的指标值为输入,对应能力综合值为输出,检验精准教学能力分级及指标权重的合理性,进而生成较为客观的评价模型;最后,利用开发的评价系统和调查问卷进行样本数据采集和模型检验,从神经网络对数据的分类、拟合及仿真结果来看,模型能够对高校教师的精准教学能力进行客观评价,教师对模型测量结果的准确性也具有较高认可度.Precision teaching to promote the personalized growth of students is the unremitting pursuit of educational ideals and national policies.As the foundation of the implementation of precision teaching,there are many problems in the existing evaluation system of teachers'teaching ability,such as unclear concepts and subjective construction of evaluation indicators.Therefore,a research on the evaluation model of college teachers'precision teaching ability based on BP neural network is carried out.Firstly,based on the theoretical research,the precision teaching ability is graded and the evaluation index framework is constructed,and the index weights are established by using the analytic hierarchy process method.Secondly,using the characteristics of BP neural network intelligent learning,the index values of different data types are taken as input and the comprehensive values of corresponding abilities are used as output,the rationality of precision teaching ability grading and index weights is tested,and a more objective evaluation model is generated.Finally,the developed evaluation system and questionnaire are used to collect samples and test the model.From the classification,fitting and simulation results of the data,the model can objectively evaluate the precision teaching ability of college teachers,and teachers also have a high recognition of the accuracy of model measurement.
