Abstract

This study aims to develop and assess the feasibility of a computational thinking skills test instrument on genetic concepts for high school students. The method used is Research & Development (R&D) with the Berkeley Evaluation and Assessment Research (BEAR) Assessment System design, which includes construct maps, item design, outcome space, and measurement models. The study was conducted in seven public high schools in Banten and the Biology Education Department of Universitas Sultan Ageng Tirtayasa in January-May 2024. The instrument’s feasibility was assessed using expert assessments (materials, evaluation, and practitioners), analysis of trial data, and student assessments via questionnaires. The average expert assessment was 98.66% (very feasible). Rasch analysis of 122 students showed item reliability of 0.5 (quite reliable) with an infit-outfit mean square in the range of 0.7-1.3, so that all questions were acceptable. Meanwhile, the average student assessment was 66.16% (practical). The results of the study show that this instrument is suitable for measuring students’ computational thinking skills in genetic concepts.
