The aim of this study is to identify and quantify trends in articles published in the “Journal of Research in Science Education” over a period of approximately a decade. Text mining was performed on 695 article titles published from 1999 to 2020. The quantitative analysis revealed the following two points: There were many articles focusing on elementary and junior high schools and on specific classroom practices in that context. Classifying and comparing the number of articles using the categories of “purpose & curriculum”, “teaching method”, “development of teaching materials”, “cognition & development”, and “teacher education”, the number of articles focusing on “teaching method”(268) and “development of teaching materials”(191) and “cognition & development” (161) was relatively large, while the number of studies examining “teacher education” (69) and “purpose & curriculum” (30) were relatively small.
