The objective of this study is to adapt the Self-Efficacy in STEM Activities Scale into Turkish and to examine whether self-efficacy beliefs in STEM activities differ according to gender and grade level. In the first stage of the research, exploratory factor analysis was conducted with data obtained from 283 middle school students (145 girls, 138 boys); in the second stage, confirmatory factor analysis, criterion validity, and internal consistency analyses were performed with data obtained from 250 middle school students (149 girls, 101 boys). According to the results of the exploratory and confirmatory factor analyses, the single-factor structure of the scale consisting of twelve items was confirmed. The Cronbach's Alpha value of the scale was calculated as .94. As a result of the analyses conducted within the scope of criterion validity, a positive and significant relationship was found between self-efficacy in STEM activities and 21st-century skills. The findings showed that the Turkish Self-Efficacy in STEM Activities Scale is a valid and reliable measurement tool. According to the analysis results, the self-efficacy beliefs of female students in STEM activities were found to be significantly higher than those of male students. Additionally, the self-efficacy beliefs of 7th-grade students in STEM activities were found to be significantly higher than those of 8th-grade students.
