An “Interactive Learning Model” to Enhance EFL Students’ Lexical Knowledge and Reading Comprehension

(1) Background: The ability to read successfully in the context of college English as a foreign language contributes to sustainable language acquisition and academic development. (2) Research problems: To enhance the sustainability of reading, the article proposed the new teaching model-interactive learning model. What is the impact of the “interactive learning approach” on EFL learners’ content and vocabulary learning? (3) Methods: “Learning Model” via the experiment class and the control class in two posttests: immediate posttest and three-week posttest. In the experiment class, students were taught with the “Interactive Learning Model” and students in the control class were instructed with a traditional approach without student interaction. (4) Results: The results of the statistical analyses indicate that the interactive learning class and the control class performed similarly on both the content and vocabulary tests in immediately posttest; but in the delayed posttests, the interactive learning class obviously outperformed the traditional class, that is, the students in the experiment class forget less vocabulary and content learning through intra/inter group discussion. (5) Significance: The significance of the research demonstrates the “Interactive Learning Model” improves students’ language learning motivation and offers the benefit of processing the foreign language more deeply and internalizing their knowledge through implicit learning.
