With the international development of China’s economy, there is an increasing demand for complex talents who are proficient in English and familiar with business operation and management of enterprises. However, it is worth exploring how to explore a proven teaching quality monitoring model for business English (BE) majors. The evaluation system of business English classroom teaching quality should not focus on the effect of teachers’ “teaching,” but on students’ “learning” experience and the effect of “learning.” English teaching should take into account the actual situation of students, especially that some students have a poor English foundation and insufficient understanding of English learning. They can improve their English cultural literacy and enhance their intercultural communication skills from learning English. Therefore, when evaluating teaching quality, indicators such as teaching methods and learning strategies should be introduced and emphasis should be placed on motivating students’ learning attitudes, emotions, awareness, and experiences to promote cooperative inquiry learning. In this paper, we propose an improved DA-BP algorithm to measure the teaching quality of BE, which has achieved good evaluation results with an accuracy rate of 93, enriched the content of business English classroom teaching and cultivated more comprehensive and better composite talents for the society.
