Abstract
The quality evaluation of English classroom teaching carries great significance in promoting English teaching reform and raising the quality of English education at university level in China. In this paper, a quality evaluation index system is introduced for the classroom teaching of English as a foreign language (EFL), and an EFL classroom teaching quality evaluation model is built based on the PSO-ELM algorithm with an ELM model constructed for comparison. A comparison shows that the PSO-ELM algorithm can obtain better accuracy with less hidden layer neurons, hence lowering the demand upon experiment samples and strengthening the fitting ability of the model. Experiment results show that the PSO-ELM algorithm is feasible to evaluate classroom teaching of English as a foreign language. The designed English classroom teaching quality evaluation index system is thus confirmed as effective, and is expected to improve the quality and management of classroom teaching of English as a foreign language.
Highlights
College English classroom teaching evaluation refers to making value judgments upon the realization of classroom teaching effects and goals of college English teachers with scientific evaluation technologies, means and methods according to the teaching rules, principles, and goals [1]
Literature [13] studies multiple evaluation systems to assess the quality of college English classroom teaching; literature [14] conducts research on college English teaching quality evaluation systems, and literature [15] advocates a facet-diversified College English teaching quality evaluation system
Literature [20] designs an optimized BP network based on a college English teaching quality evaluation model; literature [21] designs a PCA-LVQ neural network for teaching quality evaluation; literature [22] studies and realizes a BP neural network- based college classroom teaching quality evaluation system; and literature [23] applies the multilayer grey evaluation method to classroom teaching quality evaluation
Summary
College English classroom teaching evaluation refers to making value judgments upon the realization of classroom teaching effects and goals of college English teachers with scientific evaluation technologies, means and methods according to the teaching rules, principles, and goals [1]. Constructing a scientific, feasible and effective teaching quality evaluation system for the classroom teaching of English as a foreign language (EFL) in China at university level carries great significance and is even imperative in improving classroom teaching and reinforcing teacher management. To realize such an ideal evaluation system, it is necessary to review the prior researches. This research, based on previous research results, studies classroom teaching quality evaluation systems and methods in the setting of classroom teaching of English as a foreign language (EFL) in China at university level. The study re-defines the new classroom teaching quality evaluation index system for English teachers, and builds a PSOELM-based English teacher classroom teaching quality evaluation model
