Adaptation of T-STEM CT Scale to Turkish: Teacher self‑efficacy and outcome expectancy for teaching computational thinking

Computational thinking (CT) skills are accepted as fundamental literacy. Although the idea that K-12 teachers should teach students CT in an interdisciplinary context is heavily expressed, there a need for measurement tool Turkish measures teachers' self-efficacy this regard. This study aims to adapt T-STEM scale, developed by Boulden et al. (2021), into and carry out validity reliability studies of scale. The original scale consists 5-point Likert 13 items. participants consisted 168 from different branches working schools. It was carried selecting application purposes convenient sampling method. Various methods were used validate According results, two-factor (Factor1: self-efficacy, Factor2: outcome expectancy) thirteen-item structure had acceptable fit with data. Consequently, measuring teaching efficacy beliefs computational confirmed.
