摘要

摘要随着在线教育的发展，教学质量的评价方法也受到了广泛关注。本文以大规模开放在线课程（MOOC）平台上的“综合英语”课程为例，建立了教学质量评价指标，设计了一种基于反向传播神经网络（BPNN）的评价方法，利用改进的遗传算法（GA）对BPNN的参数进行了优化，并建立了改进的GA-BPNN模型。结果发现，改进的GA-BPNN模型的输出与实际值之间的误差最小，在0.01-0.04之间，表明该模型是稳定的；改进的GA-BPNN模型的平均绝对百分比误差（MAPE）和均方根误差（RMSE）分别为0.051和4.778，优于BPNN和GA-BPNN模型。结果验证了改进的GA-BPNN模型的可靠性。该模型可用于实际教学。

Research on the Evaluation Methods of English Teaching Quality in the Context of Online Education

ABSTRACT With the development of online education, the evaluation method of teaching quality has also received wide attention. This paper took the “Comprehensive English” course on the Massive Open Online Courses (MOOC) platform as an example, established teaching quality evaluation indicators, designed an evaluation method based on a back-propagation neural network (BPNN), optimized the parameters of the BPNN by the improved genetic algorithm (GA), and established an improved GA-BPNN model. The results found that the error between the output of the improved GA-BPNN model and the actual value was the smallest, between 0.01 and 0.04, showing that the model was stable; the mean absolute percentage error (MAPE) and root-mean-square error (RMSE) of the improved GA-BPNN model were 0.051 and 4.778, respectively, which were superior to BPNN and GA-BPNN models. The results verify the reliability of the improved GA-BPNN model. The model can be applied in practical teaching.

期刊介绍： Information networking is an enabling technology with the potential to integrate and transform information provision, communication and learning. The New Review of Information Networking, published biannually, provides an expert source on the needs and behaviour of the network user; the role of networks in teaching, learning, research and scholarly communication; the implications of networks for library and information services; the development of campus and other information strategies; the role of information publishers on the networks; policies for funding and charging for network and information services; and standards and protocols for network applications.
