STEM Self-Effıcacy Perception Scale (STEM-SPT) Development Study

Öz

The purpose of this research is to develop the STEM Self-Efficacy Perception Scale (STEM-SPS) for middle and high school students. The research was carried out with a total of 656 students studying in the eighth and twelfth grades in Turkey in the spring semester of the 2020-2021 academic year. The Kaiser-Meyer-Olkin index of the scale was ,920 and the Bartlett test was significant. The Cronbach Alpha reliability coefficient of the scale was ,93; test-retest reliability coefficient was calculated as 0,86. With the factor analysis, it was determined that STEM-SPS has a four-factor structure (Science, Technology, Engineering, Mathematics) and this structure is compatible with STEM education, which is explained theoretically as a result of confirmatory factor analysis. This 5-point Likert-type scale consists of 28 items. Thus, a valid and reliable scale for measuring STEM self-efficacy perceptions of secondary and high school students was obtained.

STEM Öz-Yeterlik Algı Ölçeği (STEM-ÖAÖ) Geliştirme Çalışması

Öz

Bu araştırmanın amacı ortaokul ve lise öğrencilerine yönelik STEM Öz-yeterlik Algı Ölçeği (STEM-ÖAÖ) geliştirmektir. Araştırma 2020-2021 eğitim-öğretim yılı bahar yarıyılında Türkiye’de sekizinci ve onikinci sınıflarda öğrenim gören toplam 656 öğrenci ile gerçekleştirilmiştir. İki aşamada toplanan bu verilerin 412’si (birinci çalışma grubu) açımlayıcı faktör analizi için kullanılırken, 244’ü (ikinci çalışma grubu) doğrulayıcı faktör analizi için kullanılmıştır. Cronbach Alfa güvenirlik katsayısı .92, test-tekrar test güvenirlik katsayısı ise 0.86 olarak hesaplanmıştır. Faktör analizi ile STEM-ÖAÖ’nün dört faktörlü (Fen, Teknoloji, Mühendislik, Matematik) yapıya sahip olduğu ve bu yapının doğrulayıcı faktör analizi sonucunda teorik olarak açıklanan STEM eğitimiyle uyumlu olduğu tespit edilmiştir. 5'li Likert tipinde olan bu ölçek 28 maddeden oluşmaktadır. Böylece ortaokul ve lise öğrencilerinin STEM öz-yeterlik algılarının ölçülmesinde geçerli ve güvenilir bir ölçek olan STEM-ÖAÖ elde edilmiştir.
