摘要
教师教学质量评价是一项主观性很强的工作,利用神经网络方法建立的教学质量评估系统的数学模型,采用各评价指标作为其输入,教学效果作为输出,基于最小二乘思想,采用梯度搜索技术,可以使网络的实际输出值与期望输出值的误差均方值最小,该数学模型具有较好的辨识精度。另外还有一种模型,利用模糊综合评判法从定量的角度较好地解决了受诸多因素影响的教学质量的评价问题的模型。
Teacher＇s teaching quality evaluation is a work with very strong subjectivity, utilize the mathematics model of teaching set up of the method of the neural network with systematic quality evaluation. It is input to adopt every evaluation index conduct, the teaching result conduct is exported, because of two minimum thoughts, adopt gradient search for technology , can make actual output value of network with expect error square minimum value of person who output,. This mathematics model has the better precision of distinguishing.Have one model in addition, utilize fuzzy to judge law solve receive multifactor teaching appraisal model of problem of quality of influence well in terms of ration synthetically.
