Exploring research topics and trends in early childhood education using structural topic modeling

Early childhood education plays a key role in fostering child development and preparing children for school and life. The aim of the present paper is to give an overview of research topics in early childhood education research based on the analysis of 39,926 scientific articles published between 2000 and 2021 and to explore research trends over time. Therefore, a structural topic modelling approach was used. The analyses show a strong increase in publication activity over the last years as well as the diversity of research topics, which provide important insights for achieving the UN Sustainable Development Goals in various areas (cultural diversity, design of inclusive learning environments, educational institutions, professional development issues, educational policy and reforms, etc.). Beside topics like cultural diversity, and inclusive learning environments more specific research topics, for example self-regulation, executive functions, numeracy, language development and physical activity have been increasingly addressed in publications over the years.
