The differentiated teaching self-efficacy and pedagogical and technological competencies of students studying in foreign countries were studied. For this purpose, the pedagogical and technological relational learning of students studying English at the university was studied. This research was carried out with qualitative research design. A case study was conducted using the qualitative research method. This method was chosen to reveal the current situation. 82 university students were voluntarily selected as the study group. In this study, which was conducted in Kazakhstan in 2021–2022, the opinions of foreign students studying at the university with voice recorders were taken. In the study, three open-ended questions prepared by the researcher were asked. The data is thematised using the content analysis method and explained in detail.
