Deep learning refers to active learning that allows students to perceive, experience, understand, and apply knowledge. Deep learning focuses on the mastery of knowledge and skills and more on the cultivation of higher-order thinking skills such as awareness, problem-solving, and knowledge transfer. In order to improve the quality of English classroom teaching in today’s colleges and universities and cultivate high-level applied foreign language talents, this paper constructs a multimodal teaching model based on deep learning theory and discusses how to apply the model to college English teaching practice in order to promote the realization of students’ deep learning, improve the effectiveness of English learning, and provide a reference for the teaching reform of college English courses.
