Analysis of HOTS-Based Assessment Instruments for Science Subjects
This study examines the Higher Order Thinking Skill (HOTS) Instrument for Science Subjects in Class IX. This activity aims to identify the appropriate and standard HOTS instrument for science subjects for grade IX students to assess higher-order thinking skills. The research and development methodology is used in this study. In this study, the HOTS instrument went through the following stages of research and development: (1) research and information gathering, (2) planning, (3) initial product development, (4) limited product trial, (5) product revision, (6) field trials, and (7) final product revision. The qualitative and quantitative data analysis was used to determine the HOTS instrument's validity, reliability, discriminatory index, difficulty index, and distractor quality criteria. The development's final result demonstrated that the HOTS instrument, in the form of multiple-choice questions with 24 items, is usable. The HOTS instrument was declared valid based on expert evaluation, with Aiken validity results greater than 0.8 in the outstanding category. The HOTS instrument has a difficulty level dominated by 50% of moderate questions, 70% of item discriminating power including having adequate discriminating power, and the effectiveness of the distractor; as much as 47.5% of the questions were in the sound and excellent categories, with a reliability of 0.85 in the very high category.
