针对网上课件点播学习方式的特点,给出了学生学习质量的评价指标体系。采用数学变换将本质上不可比较的原始指标值进行标准化处理,使其具有可比性。利用BP神经网络模型,对学生学习质量进行评价,通过实验表明了评价模型的有效性。
According to the characteristics of online courseware on-demand learning mode, the evaluation index system of students’ learning quality is given. Mathematical transformations are used to standardize the original index values, which are not comparable in nature, to make them comparability. The use of BP neural network model to assess the quality of student learning, experiments show the effectiveness of the evaluation model.
