Abstract: The application of mind mapping in English language education and language teaching not only follows the basic rules of memorizing, reading and thinking training, which helps learners deepen their understanding, but also effectively facilitates people’s logical thinking and greatly improves the efficiency of English teaching and learning. As a teaching tool, mind mapping can effectively promote learners’ active exploration and discovery of knowledge when properly used in classroom teaching, highlighting the characteristics of the teaching mode of “discovery learning” and giving full play to its advantages.
