The instrument analysis of students’ problem-solving ability on hybrid learning model using ETNO-STEM Approach through Quest Program in COVID-19 Pandemic

Abstract

This article explains the result of the instrument test of students’ problem-solving ability on hybrid learning model using Etno-STEM approach through Quest program. The study was conducted through validation of experts and revisions which was followed by field test on 143 students. Content validity was analysed using Aiken’s V index, while Partial Credit Model (PCM) with one-parameter logistic of Quest program was used for construct validity analysis. The finding revealed that the Aiken index gained 0.6 for the language clarity (valid) and 0.81 for the theory conformity, grouped into good validity. The value of IFNIT t for 21 items was ±2.0 and it is concluded that the instrument fits with the items and the testers completed the examination of 1 PL model. The reliability of the test was 0.44, so the instrument was good to be used to measure problem solving ability.
