Development of HOTS-based assessment instruments in calculating building structures moment for Vocational High Schools (VHS)

Vocational High School (VHS) is a secondary school that offers skill-based education with the main aim of providing students with knowledge and skills that are suitable to apply in the workplace after graduation. Digitalization in the industrial revolution 4.0 era requires VHS graduates to think analytically, adaptive, creatively, and innovative at a higher level. Therefore, a more weighty test instrument is needed to determine students’ thinking skills by measuring higher-order thinking skills or HOTS. This study aims to confirm the extent to which the indicators in the instrument items can measure the achievement of material or learning competence in engineering mechanics and the implications of measurement models for HOTS questions on engineering mechanics. Engineering mechanics is a concept of physics that discusses structures and their working loads. This study used is Research and Development (R&D) method with Confirmatory Factor Analysis (CFA) data analysis techniques. The number of samples used in the study was 200 VHS students with property construction technology expertise. The analysis process is carried out with the help of JASP software. The results obtained in this study are 11 measurement models obtained using JASP, namely the fit measurement model.
