The innovation of English teaching mode in the digital era has become the focus of attention in the education sector. New technologies such as AI, big data, and virtual reality provide intelligent and personalized learning experiences for English language teaching and promote the development of the teaching mode in the direction of more flexibility and efficiency. This study explores the transformation of the English language teaching mode driven by digital technology and its impact on the acquisition effect. The study adopts a variety of methods to design and implement an AI-enabled BOPPPS teaching model. Two classes of 70 students in the first year of senior high school in K High School in Kelamayi City were selected as the research subjects, and the experimental group adopted the AI+BOPPPS teaching model, while the control group adopted the traditional teaching model for a 15- week experimental study. Changes in English learning attitudes and vocabulary knowledge breadth before and after the experiment were analyzed by paired-samples t-test. The results show that the mean value of the post-test of students’ English learning attitude in the experimental group is 14.451, and that of the control group is 11.232, with a difference of 3.219 (P=0.000<0.05), which is a significant difference; and the post-test of vocabulary knowledge breadth in the experimental group is 69.17, which is higher than that of the control group is 60.24, with a difference of 8.93 (P=0.016<0.05), which is a significant difference. The study shows that the AI-enabled BOPPPS teaching model effectively enhances students' learning interest, engagement and knowledge mastery through the integration of AI technology in the introduction, pre-test, participatory learning and post-test, and significantly promotes the cultivation of students' attitudes toward English language learning and the improvement of vocabulary knowledge breadth.
