Abstract:

Speaking is the transmission of feelings and thoughts through sounds. It plays an important role in the maintenance of social relations and the development of democratic culture. Self-efficacy perception, which is one of the affective indicators of speaking skill, has an important effect on individuals' speaking performance. The aim of this study is to develop a valid and reliable scale for determining the speaking self-efficacy perceptions of secondary school students. For this purpose, respectively; establishment of an item pool, obtaining expert opinions, pilot application, data collection and data analysis procedures were carried out. The data were collected from 610 secondary school students for the validity and reliability analyses of the scale. The scale consists of 24 likert type items with five degrees. It was found that the total explained variance was 45.5% and that the items were grouped under four factors after the exploratory factor analysis. And also, the model fit indices were seen according to confirmatory factor analysis results in perfect fit (RMSEA=.034, RMR=.040, SRMR=.0349), and also in well fit in terms of AGFI=.935, CFI=.960, GFI=.949, NFI=.909. The internal consistency of the scale is .815. These findings show that the scale is a valid and reliable measurement tool.
