The aim of the research is to determine the predictive power of prospective physical education teachers' attitudes towards educational technologies for their technological pedagogical content knowledge. In this study, a relational research model was used on a study group that consisted of 529 (M[subscript age]=21.49, SD=1.44) prospective physical education teachers. As a data collection tool, a "technology attitude scale" and a "technological pedagogical content knowledge scale" were used. Regarding analyses, inferential statistics as correlation and regression analyses were used, in addition to descriptive analyses. At the end of the research period, it was observed that attitudes towards educational technologies had a high-level effect on technological pedagogical content knowledge, and the variables that constituted a sub-dimension of the attitude scale for educational technologies explained 31% of the total variance in technological pedagogical content knowledge. In addition, it was established that attitudes towards educational technologies and the technological pedagogical content knowledge of prospective physical education teachers were at a high level.
