English Classroom

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.

The Index System

Based on four categories of indexes including intensity indexes, system indexes, supporting indexes and characteristic indexes, this paper combines with actual characteristics of Chinese ports, discusses about and builds a green and low-carbon port evaluation index system, and puts forward a set of simple and practical evaluation methods and standards. With case study of Guangzhou Port, this paper also conducts empirical evaluation of current development level in 2013 and planning level in 2020 respectively, and verifies scientific validity of the index system.
