Development of digital literacy assessment instruments using the rasch model measurement analysis method in high school students in Indonesia

Abstract

Digitization in day-to-day life has significant implications for education. This increasing use of digital technology requires the presence of digital literacy, which is one of the vital competencies that must be mastered by students, especially in today’s era where everything is digital. To get an accurate picture of the digital literacy level in students, a quality measuring instrument is necessary. Thus, the researchers conducted this study which focused on developing a measurement scale or digital literacy instrument for students using the Rasch model. The research participants were 317 high school students in Madiun Regency and Madiun City. Based on the analysis results using the Winsteps program, it is found that there are 46 items (out of 50 items) that meet the item-model fit index, with a reliability coefficient alpha of 0.97. Overall, it can be concluded that the digital literacy scale of these students has good psychometric properties, hence it can be used for assessment and research.
