摘要:Research Problem / Aim The aim of this study was to introduce the psychometric properties of the Student Engagement Scale for Online Learning which was used to measure the engagement of students in online learning environment by using the validity and reliability study in the sample of university students who took lessons online. Method There were studies conducted with the scale in Turkey. However, this study carried out with a sample of students who meet the requirement of taking online course. Original scale consists of three sub-dimensions. Name of the sub-dimensions are “Behavioral Engagement”, “Emotional Engagement” and “Cognitive Engagement”. The psychometric properties of the instrument were presented by translation, linguistic equivalence, validity and reliability studies. Translation to Turkish of the scale was made by the researchers. A preliminary form was formed by taking the opinions of a total of six experts that one of them from the department of ELT (English language teaching), one of them from educational measurement & evaluation, one of them from Turkish language teaching, one of them from education psychology, and two of them were educational technology. For linguistic equivalence, the preliminary form was applied to 20 ELT students. The correlation analysis show that the linguistic equivalence of the scale had shown significant correlation between the Turkish and English forms. After the linguistic equivalence was provided, last form of the scale was applied to 587 university students enrolled at the Vocational School of Technical Sciences, Amasya University. Results and Conclusions As a result of the analyzes, confirmatory factor analysis fit indices was calculated as Χ2/sd: 2.827, GFI: .93, AGFI: .91, CFI: .98, NFI: .97, RMSEA: .05 and SRMR: .06. Cronbach alpha internal consistency coefficients that calculated for the reliability of the sub-dimensions were between .71 and .86. The results obtained from confirmatory factor analysis and reliability analyses was indicated that the scale is reliable and valid. It is suggested to use the scale in determining the student's engagement in online learning environments research.
