Research on the Ecological Mechanism Construction and Sustainable Development of College English Teaching

Under the backdrop of the new era, university English teaching faces multiple challenges, including the transformation of teaching mechanisms, breakthroughs in quality bottlenecks, the redefinition of assessment standards, and the adjustment of developmental directions. Traditional linear approaches are insufficient to address these emerging issues. This paper, as a conceptual and theoretical study, adopts an ecological perspective to explore sustainable pathways for reform. Drawing upon ecological theories, it analyzes the ecological connotations of university English teaching and proposes a five-dimensional practice framework encompassing teacher development, textbook system construction, curriculum design, classroom ecology, and learning evaluation. The findings suggest that integrating these dimensions into a holistic ecological mechanism can enhance students’ English competence, promote cross-cultural literacy, and support the high-quality and sustainable development of university English instruction.
