Abstract

Zoom has emerged as an alternative application used by most communities in the world of education. The purpose of this study was to produce empirical evidence on the validity and reliability of the UTAU-ZOOM2 instrument for students who had attended Risale-i Nur learning sessions through ZOOM. This Risale-i Nur learning session is a non-formal education referring to a planned and structured personal and social education program and process designed to improve various skills and competencies outside the formal education curriculum. The objective of this study was to measure the instrument using item polarity test, standardized variance test, study instrument reliability test and individual-item distribution map in Rasch analysis. The findings of the study showed that only 16 items were received and met the requirements of the Rasch Model out of the total 24 items. However, all items can be improved in terms of sentence structure and language with content and language experts consultation to further improve the validity and reliability of the UTAU-ZOOM2 questionnaire. This study shows that Rasch analysis helps novice researchers improve systematically in term of constructing questionnaires to produce quality research data.
