This article explores modern interactive methods for teaching English grammar to future educators, emphasizing their role in developing grammatical competence. The focus is placed on three pedagogical technologies: the Carousel method, the Snowball method, and Problem-Based Learning (PBL). Each approach is analyzed in terms of its application to mastering complex grammatical structures, especially Passive Voice. The study highlights the advantages of these methods, including improved memorization, increased motivation, development of communicative skills, and critical thinking. At the same time, the article examines the potential challenges of implementation—such as differing student levels, time constraints, and the need for teacher preparation—and offers practical recommendations for overcoming them. By integrating these approaches into grammar instruction, educators can create a more dynamic, learner-centered, and effective language learning environment.
