Evaluation of the Quality of Audio-Visual Aided Teaching of English

摘要

As one of the most widely used mainstream languages in the world, English is a key learning course for primary and secondary school students as well as college students. Using traditional classroom teaching, teachers often judge whether students' pronunciation is standard or not according to their own experience. The effect of their teaching largely depends on the level of the teachers' oral English, which is not an objective measure. Using voice visualization software, the pronunciation of spoken English can be displayed in a more intuitive form. The differences between standard pronunciation and the students pronunciation can be distinguished more quickly and accurately using this software, in order to correct the pronunciation. This paper briefly introduces Praat, audio-visual software used for teaching spoken English. 100 students in a college were then divided into two groups. One group was taught using traditional teaching methods, and the other group was taught using Praat. A questionnaire survey was then carried out. The results of the survey showed that the students who were taught by Praat had a marked improvement in stress and fluency. The results also showed that most people held a positive attitude towards Seaming English assisted by the Praat software. Therefore, English pronunciation and intonation teaching based on audio-visual software can improve the effectiveness of teaching and students' interest in learning.
