Teacher Effectiveness Research from Margins to Mainstream: A Bibliometric Mapping of Eight Decades of Educational Leadership and Practice

Abstract

Teacher effectiveness has long been recognised as a key determinant of educational quality. However, rapid transformations in education systems driven by globalisation and digitalisation have led to substantial growth. Despite this expansion, systematic mapping of the trends remains limited. To address this gap, this study adopts a bibliometric approach to synthesise and visualise the evolution of teacher effectiveness research. Data were retrieved from the Scopus database using an advanced search strategy, resulting in a final dataset of 1,286 peer-reviewed journal articles. Scopus Analyzer was used to examine publication trends, citation patterns, and geographical distribution, while OpenRefine was utilized for data cleaning. VOSviewer was then employed to generate visualisations of keyword co-occurrence and international co-authorship networks. The findings indicate a sustained increase in publications from the early 2010s onwards, reflecting heightened scholarly attention to teacher effectiveness. The United States, United Kingdom, and Australia emerge as leading contributors, alongside growing participation from Asia and the Middle East, signalling the field’s globalisation. Keyword analysis identifies professional development, teacher education, self-efficacy, and instructional quality as dominant themes, with emerging digital-related concepts. Overall, the study offers a systematic overview of the knowledge structure and research dynamics of teacher effectiveness, providing insights to inform future research and policy directions.
