Abstract:Teaching quality evaluation in college teaching is a multi-factor,multi-variable fuzzy nonlinear process.By applying BP neural network principle,the model of teaching quality evaluation was established in this paper.And then authenticated with testing data after trained by means of Neural Network Toolbox in Matlab.The result shows that the method,applied to teaching quality evaluation,can both overcome the subjective factors of evaluation main body in evaluation process and bring the satisfactory evaluating results,and it has the widespread serviceability.
