Purpose: This study aims to explore the intersection of English and education through a systematic review of academic literature. It focuses on identifying key research themes and future research areas, particularly in sustainable teaching and learning practices within the field of English education. Design/methodology/approach: This study analyzed 84 papers published between May 2000 and May 2024 using a bibliometric approach. Keyword co-occurrence analysis was used to identify clusters of research themes. These clusters helped in categorizing research areas and provided a systematic overview of the current literature in English education. Findings: This study identified four distinct research clusters that represent core themes in English education research. These themes informed the development of a research agenda focusing on areas that require further exploration, particularly in sustainable teaching and learning practices. This study also examined the theoretical and practical implications of these themes. Practical implications: The findings provide educators and policymakers with a framework to prioritize research efforts, allocate resources and develop strategies to enhance sustainable teaching and learning practices in English education. Social implications: By emphasizing the importance of sustainability in teaching and learning, this study promotes educational practices that contribute to long-term improvements in both student outcomes and teacher development. It identifies opportunities for sustainable growth in English education that benefit diverse learners. Originality/value: To the best of the author's knowledge, this is the first study to apply a bibliometric approach to systematically review the intersection of English and education. By identifying core research clusters and creating a research agenda, this study contributes new insights into sustainable practices in English education.
