The popularization of mobile internet devices is the foundation of the reformation in foreign language learning learning mode. And studies on online foreign language learning anxiety has been the hot topic recently. This thesis applied Foreign Language Classroom Anxiety Scale to explore the relationship between online English learning anxiety and achievement. And the results demonstrated that Chinese college students are showing moderate English learning anxiety. Online English learning anxiety is negatively correlated with language achievement. It worth noting that there exist significant differences between female and male students towards detailed elements in language anxiety scale.

Oral English instruction plays a pivotal role in educational endeavors. The emergence of online teaching in response to the epidemic has created an urgent demand for a methodology to evaluate and monitor oral English instruction. In the post-epidemic era, distance learning has become indispensable for educational pursuits. Given the distinct teaching modality and approach of oral English instruction, it is imperative to explore an intelligent scoring technique that can effectively oversee the content of English teaching. With this objective in mind, we have devised a scoring approach for oral English instruction based on multi-modal perception utilizing the Internet of Things (IoT). Initially, a trained convolutional neural network (CNN) model is employed to extract and quantify visual information and audio features from the IoT, reducing them to a fixed dimension. Subsequently, an external attention model is proposed to compute spoken English and image characteristics. Lastly, the content of English instruction is classified and graded based on the quantitative attributes of oral dialogue. Our findings illustrate that our scoring model for oral English instruction surpasses others, achieving the highest rankings and an accuracy of 88.8%, outperforming others by more than 2%.
