SECOND-ORDER FACTOR ANALYSIS OF TEACHERS' CORRECT USE OF THEIR VOICES SCALE IN CLASSROOM MANAGEMENT (TCUVS)

Abstract

The aim of this study was to test the validity and reliability of the Teachers' Correct Use of their Voices Scale (TCUVS) in classroom management and to try to explain the factors of the scale using the second order factor analysis. The participants of the study were 1095 teachers working at various educational levels in the province of Antalya, Turkey in the 2018-2019 academic year. Exploratory and confirmatory factor analysis was used in the development of the TCUVS. The scale developed as a result of the first order factor analysis consists of seven dimensions (voice health problems, voice protection, the harmony between voice and body, correct use of voice, correct use of speech voice, directing voice, voice distortion) and 31 items. The results of the second-order confirmatory factor analysis conducted to better evaluate the results of the seven-dimensional first-order confirmatory factor analysis and to summarize the dimensions of the scale showed that the model with two factors (voice problems and professional use of voice) and six sub-dimensions (voice protection, the harmony between voice and body, correct use of voice, correct use of speech voice, directing voice, voice distortion) better fits the data statistically. A moderate relationship was found between the factors of voice problems and professional use of voice. It can be said that the internal consistency of the dimensions of the TCUVS was strong; the confirmatory factor analysis goodness of fit criteria and combined reliability level were adequate; and only the rate of mean variance explained was found to be limited. Therefore, the fit of the model to the data was found sufficient. Article visualizations:
