Abstract: Starting from the current status of professional English courses for graduate students majoring in materials and chemical engineering, this paper summarizes the teaching content of professional English based on various research fields and directions. It delves into constructing a multi-dimensional interactive teaching model combining ‘split classroom + flipped classroom’ methodologies, utilizing modular and progressive teaching strategies. This model aims to help students build a structured understanding of professional English knowledge, thereby fostering their enthusiasm and self-motivation in learning, and enhancing their learning efficiency. The multi-dimensional interactive teaching model enriches the learning experience by increasing the practicality and interactivity of the learning process, and extends the temporal and spatial interaction between teachers and students to its fullest potential. Utilizing the benefits of MOOCs both before and after class ensures the consolidation of learning outcomes. The paper also discusses enhancing student autonomy through various group activities, including ‘simulated academic seminars’, ‘English Pictionary’, and ‘research posters’. The findings of this study offer vital theoretical and practical insights for the reform of professional English curricula in the field.
