Development of higher order thinking skills based problem solving questions on the nervous system concept

Research on the development of higher order thinking skills (HOTS) questions based on problem solving on neural system material aims to produce valid and reliable HOTS questions. The development of higher order thinking skills questions refers to Anderson & Karthwohl and Polya frameworks. The questions that developed are a multiple choice problem with five alternative answers. The evaluation process includes self-assessment, expert review, one-to-one and small groups. Readability questions are tested at the one-to-one stage. The results of the small group stages are then analysed item items, namely item validity and item reliability. The validity of items is calculated based on expert review validation, while the reliability of the questions is calculated using Anates 4.0. The results of the research conducted showed that the questions developed were valid (86,1%) and reliable (0,35). The results of this study can be used as a reference for teachers to provide HOTS questions and familiarize students with solving problems with these characteristics.
