State-of-the-art of CLIL Research Using Bibliometric Approach: 2005-2021


The increasing globalization and internationalization has had major impact in elevating the importance of English language education. Notably, amongst the numerous approaches, content and language integrated learning (CLIL), which focuses on concurrent teaching and learning of both foreign languages and subject matters, has garnered much research interest and developed into a field of research. However, despite the wealth of reviews devoted to specific CLIL topics, there has not been any attempt in presenting a comprehensive overview on the subject using bibliometric approaches. The current study aims to fill this gap by providing a state-of-the-art overview on the most relevant authors, journals, and articles, the core research themes and topics, and the collaboration patterns in the field of CLIL. The data comprise of 451 articles indexed on the Web of Science database published between 2005 and 2021. Performance analysis of CLIL using R Bibliometrix revealed the top productive authors, journals, and countries and most locally cited authors, journals, and articles in CLIL research. Bibliographic coupling using VOSviewer identified eight core clusters of research interest including (1) Translanguaging, (2) Outcome, (3) English as medium of instruction (EMI), (4) Issues, (5) CLIL in the European context, (6) Policy, (7) Language vs content, and (8) Definition and introduction to CLIL. Co-authorship analysis revealed nine clusters comprising diverse countries collaborating in CLIL research. This state-of-the-art bibliometric analysis of CLIL research provides a starting and reference point for scholars in generating and expanding future studies in the field.
