Abstract
Research on student engagement has been incrase in recent years. Therefore, to determine the high or low level of student engagement, a valid and reliable measuring instrument is required. This means that the measuring instrument of student engagement must measure only the construct of student engagement reliably and consistently in measurement. The purpose of this research was to test the validity and reliability of the student engagement construct based on Fredrick et al theory. The components of student engagement that are used as a reference for making measuring instruments consist of behavioral engagement, emotional engagement, and cognitive behavior. The study was conducted on 100 high school students using a proportional sampling technique. The measuring instrument is constructed using a semantic differential scaling model. The validity and reliability test used the confirmatory factor analysis (CFA) approach with the help of PLS 3.2.9 software. The results showed that the student attachment measurement tool was declared valid and reliable to be used as a measuring tool. The convergent and discriminant validity tests have met the standards, with loading factor score value of P> 0.5, while the Cronbach alpha reliability score is 0.753 and the composite reliability is 0.835. This measuring instrument is also declared fit with an RSMR value of 0.033. 7 items dropped out of the 18 items tested.
