Öğretmen Öz-Yeterlik Algısı Ölçeğinin Meta-Analizle Güvenirlik Genellemesi

Abstract

The objective of this study was to estimate the overall Cronbach's alpha value of the total score and three subscales of the Teacher Self-Efficacy Scale. For this purpose, the study was conducted with 189 Cronbach's alpha values from 187 different studies for the total score of the scale and 157 Cronbach's alpha values from 156 different studies for the subscales. The analyses were conducted with the Random Effect model using Bonett transformation. The average Cronbach's alpha value for the total score of the scale was .931, .854 for the efficacy for student engagement subscale, .871 for the efficacy for instructional strategies subscale and .869 for the efficacy for classroom management subscale. In order to explore the variability in Cronbach's alpha values, moderator variable analyses were conducted with three categorical variables and the results were reported. As a result, Cronbach's alpha values of the total score and subscales of the scale were found to be at an adequate level and recommendations were made for researchers.
