In the information age, science and technology have profoundly impacted the education industry with their wide penetration. Scientific development advances new demands and challenges for education, influences traditional areas of education, leads to conflicts in education between the new and the old, the advanced and the backward, and ultimately promotes educational innovation and development. Many new technology products have been adopted in education. These new technologies are being applied to improve teaching effectiveness on the one hand and to promote the popularisation and popularisation of education on the other. As a kind of humanities, English has undergone many changes in English education in recent years due to informatization. Most academics now concentrate on how and whether students, the audience, can embrace this transformation. There is, however, no clear assessment system for the effect of teaching English, and in the process of teaching English, effective feedback is an important component of effective instruction. The key factors to determine whether to give effective feedback are students' self-efficacy and learning engagement. Therefore, this study adopts an adaptation-mode integration technology acceptance questionnaire to analyze the influence of general self-efficacy and learning engagement on English teaching effectiveness. Drawing on the learning theory of modern educational technology, this study conducts an empirical investigation based on the technology acceptance perspective, comprehensively reviews the application of modern information technology in English language education, and advances plans and options for improving the effectiveness of education in the future.
