Professional Value-Oriented Life Tendency Scale Teacher Form Validity and Reliability Study
Abstract
In this study, it is aimed to develop a measurement tool to determine teachers' professional value-oriented living tendencies. By scanning the literature, the scale development stages were followed and a draft scale form with 50 items was created. The prepared draft form was applied to 25 teachers as a preliminary test and then rearranged in line with expert opinions. The prepared form was applied to a research group consisting of 1130 teachers working in public schools (primary school, secondary school and high school) in the central districts of Ankara in the spring term of the 2020-2021 academic year. Study Group 1 data were used to determine the validity and reliability of the scale, and Study Group 2 data were used for CFA. EFA was applied to the data obtained from 300 teachers, called Study Group 1, within the scope of validity and reliability study. In the second stage, Confirmatory Factor Analysis (CFA) was conducted on the data obtained from 875 teachers, called Study Group 2, in order to verify the factor structure of the scale in another sample. As a result of the exploratory factor analysis, it was determined that the scale had a three-factor structure. The Cronbach Alpha internal consistency coefficient was 0.98 for the overall scale, 0.96 for the 1st sub-factor, 0.77 for the 2nd sub-factor, and 0.86 for the 3rd sub-factor. As a result of confirmatory factor analysis, the RMSEA value was found to be 0.049. In addition, the GFI, AGFI, CFI, NFI and NNFI values, which are expressed as goodness fit indices, are found to be 0.99, which is very close to 1, which shows that good fit values are obtained. As a result of the analyzes made, a 33-item scale form with the necessary measurement reliability was developed to serve to measure the professional value-oriented life tendencies of teachers.
