The aim of this study is to compare the master's (MA) theses in Türkiye (TR) and Finland (FIN) published between 2015-2019. A total of 765 theses were analysed in terms of year, discipline, methodological approach, research method, didactic foci, data collection tool, target group, and sample size. The results showed that FIN theses grounded on research-based teacher education, and prioritised research methods for the understanding and development of learning environments. FIN theses research questions focussed on teacher, student, and content interaction and covered upper secondary school and bachelor's students and teachers. In contrast, majority of TR theses involved the quasi-experimental, survey, and case study methods, and research questions focussed on examining student characteristics and student-content interaction. The majority of TR theses were conducted with student from lower and upper secondary school, undergraduates and teachers as well as TR theses conducted with different sample types and sizes.
