Abstract

The purpose of this study is to develop a reliable and valid self-efficacy scale which intends to measure academics’ self-efficacy beliefs in oral communication in a foreign language. The data in this study were collected from 395 academics working in state and foundation universities in Turkey. The 29 items in the scale trial form were rated on a 10-point Likert scale. After ensuring that the assumptions were met, an exploratory factor analysis was performed, which indicated a structure with one factor and 19 items. The 19 items in one dimension explained 75.709% of the variance in academics’ self-efficacy beliefs in oral communication in a foreign language. The overall internal consistency reliability of the scale was high, with a Cronbach’s alpha reliability coefficient of .982. The results indicate that our self-efficacy instrument is reliable and valid for measuring academics’ oral communication self-efficacy beliefs in a foreign language.

Özet

Bu araştırma, akademisyenlerin yabancı dilde sözlü iletişim kurabilmelerine ilişkin özyeterlik inançlarını ölçen, güvenirliğ ve geçerliğ yüksek bir ölçek geliştirmek amacıyla yürütülmüştür. Araştırmaya devlet ve vakıf üniversitelerinde görev yapmakta olan 395 öğretim elemanı katılmıştır. Araştırmanın verilerinin toplanmasında kullanılan 29 madde, 10 kategorili olarak derecelendirilmiştir. Tüm sayıltıları incelendikten sonra gerçekleştirilen açımlayıcı faktör analiziyle 19 maddelik tek boyutlu bir yapı elde edilmiştir. Toplam 19 madde tek boyutta akademisyenlerin yabancı dilde sözlü iletişim kurabilme özyeterlik inancına yönelik varyansın %75.709’unu açıklamaktadır. Ölçeğn bütününe ait hesaplanan içtutarlılık anlamındaki Cronbach alfa güvenirlik katsayısı 0.982 olarak bulunmuştur. Elde edilen yapı geçerliğ kanıtları da dikkate alındığında; ölçeğn akademisyenlerin sözlü iletişime kurabilmelerine yönelik özyeterlik inançlarını ölçmede güvenilir ve geçerli bir ölçek olduğu sonucuna varılmıştır.
