With the rapid development of network communication technology, since the beginning of the 21st century, flipped classroom, as a new hybrid teaching method based on computer technology, has changed the traditional teaching method and formed a teaching process of "learning first and teaching later". Applied to many fields. In university teaching, flipped classroom is widely used, changing students' passive learning to active learning, adjusting classroom time and learning time, emphasizing students' autonomous learning, and greatly improving students' enthusiasm for learning. From the perspective of the cohesion and richness of vocabulary in the flipped classroom model, this paper examines the effect of vocabulary in college writing under the background of flipped classroom and the teaching method. Through the discussion of the relevant concepts of the flipped classroom model, this paper shows the relevant characteristics of the flipped classroom. College English writing is a very important subject, and the English teaching mode has greatly helped college students to learn English writing. Therefore, this paper focuses on the application of vocabulary cohesion and richness in college English writing under the flipped classroom mode. The final results of the study showed that the students in the experimental group scored 88 and 92 on lexical cohesion and richness, respectively, with an average score of 90. It can be seen that the flipped classroom model is helpful to improve the vocabulary cohesion and richness of students' English composition.
