Özet:

The aim of this study is to develop a reliable and valid scale that aims to measure the proficiency perceptions of Turkish language learners regarding productive language skills. In this scale development study, exploratory sequential design, which is one of the mixed research designs, was used. The participants of the research consisted of 224 foreign undergraduate students studying at TÖMERs affiliated to Atatürk and Gaziosmanpaşa universities between the academic years of 2020-2021. The Lawshe technique was used to determine the content validity of the scale items. The data obtained as a result of the scale application were analyzed in SPSS 18.0 and LISREL 8.4 programs. While examining the construct validity of the scale, exploratory factor analysis technique was used. After it was decided by exploratory factor analysis that the scale consisting of 26 items had a single factor structure, confirmatory factor analysis technique was also used to confirm this structure. According to the exploratory factor analysis findings, it was decided that the scale developed based on both the explained total variance values and the line graph values has a single factor structure. When the fit indices obtained as a result of confirmatory factor analysis were examined, it was determined that all fit indices showed acceptable fit. As a result of the reliability test, the Cronbach Alpha value was calculated to be 0.93; It has been determined that this value being at an acceptable level indicates that the internal consistency value of the scale is high. At the end of the study, a reliable and valid single factor scale consisting of 26 items was reached.
