Developing Efficacy Scale for Teaching Students with Developmental Disabilities and an Analysis by the Special Education Teachers’ Sample
Abstract
This study aimed to develop a scale to assess the efficacy of teaching students with developmental disabilities and test it with a sample of special education teachers (SETs) by demographic characteristics. Exploratory and confirmatory factor analyses were performed to determine the scale’s validity and reliability. The exploratory factor analysis revealed that the scale has two factors. The first factor, “Cooperation and Rights Advocacy,” was explained as 28.09% of the total variance, with a Cronbach’s alpha coefficient of .85. The second factor, “Teaching and Classroom Management,” was explained as 18.02% of the total variance, with a Cronbach’s alpha coefficient of .79. Cronbach’s alpha coefficient for the whole scale was calculated as .82. Also, McDonald’s omega coefficients were calculated as .86 for the first, .79 for the second factors, and .82 for the whole scale. As a result, the scale is a valid and reliable tool for determining SETs’ efficacies. While the efficacy of SETs did not differ significantly according to the gender and educational level they teach, it differed significantly according to their educational level, disability group of their teaching, and professional seniority.
