                            <p>STEM activities include processes that involve different disciplines and produce solutions to the problems faced by students. In this study, it was aimed to develop a valid and reliable scale to determine teachers&#039; self-efficacy perceptions of STEM activities. The study group of the research consists of 473 teachers (308 for EFA and 165 for CFA). The draft scale form, which was prepared in a 5-point Likert type with 51 items, was applied to 308 teachers. The data were presented to expert opinion by calculating item-total score correlation values. According to the findings, the draft form was transformed into a form consisting of 26 items. Then, exploratory factor analysis (EFA) was performed. According to the results of the analysis, six items were removed from the draft form. It was determined that the reliability coefficient (Cronbach alpha) of the scale form consisting of 20 items was 0.97 and it explained 64.569% of the total variance in the single-factor structure. Confirmatory factor analysis (CFA) was performed to determine the construct validity. As a result of confirmatory factor analysis, it was determined that the fit indices were provided at a high level. According to these results, it can be said that the scale is a valid and reliable measurement tool.</p></trans-abstract>

Bu araştırmada, öğretmenlerin STEM etkinlikleri öz yeterlik algılarını belirlenmesi için geçerli ve güvenilir bir ölçeğinin geliştirilmesi amaçlanmıştır. Araştırmanın çalışma grubu, 473 (308 kişi açımlayıcı faktör analiz (AFA) için ve 165 doğrulayıcı faktör analizi (DFA) için) öğretmenden oluşmaktadır. 51 maddelik 5’li Likert tipinde hazırlanan taslak ölçek formu, 308 öğretmene uygulanmıştır. Veriler, madde-toplam puan korelasyon değerleri hesaplanarak uzman görüşüne sunulmuştur. Elde edilen bulgulara göre, taslak form 26 maddeden oluşan forma dönüştürülmüştür. Daha sonra AFA yapılmıştır. Analiz sonucuna göre, 6 madde taslak formdan çıkartılmıştır. 20 maddeden oluşan ölçek formunun iç tutarlık güvenirlik katsayısı (Cronbach Alpha) 0.97 ve tek faktörlü yapıda toplam varyansın %64.569’unu açıkladığı belirlenmiştir. Yapı geçerliliğini belirlemek amacıyla DFA yapılmıştır. Doğrulayıcı faktör analizi sonucunda, uyum indekslerinin yüksek derecede sağlandığı tespit edilmiştir. Bu sonuçlara göre, ölçeğin geçerli ve güvenilir bir ölçme aracı olduğunu söylenebilir.</p></abstract>
