Exploring the Online Platform Construction of English Movie Audiovisual Speaking Blended Teaching Mode Based on POA Theory of Production-Oriented Approach

Abstract

This article is concerned with improving college students’ English audiovisual speaking ability in the context of the development of the times. Based on the SPOC (Small Private Online Course) teaching platform and the POA (Production-Oriented Approach) theory, the article constructs a blended teaching mode of English movie audiovisual speaking course. This model extracts English movie audiovisual features through the multimodal fusion of audiovisual correlation perception and audiovisual recognition. The article adopts CRNN (Convolutional Recurrent Neural Network) model and 3D convolutional structure to build a multimodal audiovisual speech recognition model for English movies. The differences between blended and traditional teaching are analyzed and the effects of integrated teaching are explored through a study of South China Agricultural University students. The study results show that the combined teaching is 0.699 points higher than the traditional teaching method in the average normalized gain score, and the audiovisual speaking ability of the students in the experimental class has improved by 76.04%. The blended teaching of English movie audiovisual speaking based on SPOC platform can effectively enhance students’ audiovisual speaking ability, thus promoting students’ cross-cultural communication ability.
