Development of educational virtual reality attitude scale: A validity and reliability study

Abstract

The aim of the study is to address a gap in the literature by developing an educational virtual reality (edVR) attitude measurement instrument, which determines college students' attitudes towards using VR technology for educational purposes. A sequential exploratory mixed method was employed to develop the measurement instrument. Initially, a qualitative approach was used to establish the face and content validity of the instrument and subsequently a quantitative approach was used to test the construct validity and reliability of attitude statement items. Critical reviews and constructive feedback were gathered from a range of parties, including target users (i.e., college students), learning technology experts, assessment and evaluation authority, and linguists of English and Turkish. The psychometric properties of edVR attitude measurement instrument were tested with a total sample of 305 sophomore, junior and senior students studying at different faculties. The exploratory factor analysis (EFA) results confirmed the single-factor structure with nine items, explaining 63.46% of the total variance and the confirmatory factor analysis (CFA) results indicated a sufficient fit of this single-factor model. The Cronbach's alpha coefficient for the edVR attitude measurement instrument was 0.92 and the test-retest reliability of the instrument was 0.94. The t-values were significant for all items for 27% of the participants to compare the top and bottom. As a result, the edVR attitude measurement instrument was valid and reliable in measuring students' attitudes towards educational VR.
