Developing a Self Efficacy Scale toward Using Rubric

The aim of this study is to develop a valid and reliable scale that can be used to measure pre-service teachers’ self belief in using rubrics. Self-efficacy scale toward using rubric was applied to 402 pre-service teachers from 3 state universities in Turkey. For the structure validity of the scale, firstly, an exploratory factor analysis was performed, and for the uni-dimensional structure that was seen to be meaningful in the first analysis, a principal component analysis was performed. In the last step of the analyses, the model, which was formed according to the basic components and factor analysis results, was tested through a confirmatory factor analysis. The scale is composed of 13 items, and the reliability coefficient was calculated to be Cronbach alpha= .91. As a result, it can be said that the developed scale is a valid and reliable measurement tool to be used in measuring self-efficacy toward using rubric.
