The purpose of this study is to determine the language equivalence and the validity and reliability of the Turkish version of the Web-Based Learning Platform Evaluation Scale (Web Tabanl? Ö?renme Ortam? De?erlendirme Ölçe?i [WTÖODÖ]) used in the selection and evaluation of web-based learning environments. Within this scope, the validity of the factor structure of this scale is examined on the basis of data collected from 482 students at 11 universities in Turkey. The results of the exploratory factor analysis (EFA) show that the 40- item, four-factor structure of the scale parallels the original scale. To determine whether this structure agrees with the sample data, first-level confirmatory factor analysis (CFA) was conducted. The findings indicate that the compliance level of the sample is good. In addition, Cronbach’s alpha reliability coefficient for the entire scale was calculated as .95, whereas McDonald’s omega coefficient, which is regarded more relevant for congeneric measurements, was calculated as .96. These results indicate that the Turkish version of this scale, with its 40-item, four-factor structure, is a valid and reliable instrument.
