The purpose of this research is to develop a scale for analyzing the technological pedagogical and content knowledge (TPACK) and self-efficacy perceptions of the social sciences teachers and teacher candidates. During the development process, an item pool has been generated by evaluating the studies made in the literature. Also, after opinions have been obtained from the experts in scale development, essential revisions have been made in accordance with these opinions. The final version of the scale has been applied to 285 teacher candidates for the validity-reliability study. As the result of the confirmatory factor analysis, 7 factors have been determined related with the scale. The Cronbach Alpha reliability coefficient of the scale has been found as 0.977. In conclusion, it is determined that the scale is valid and reliable for making the study.
