Reconstruction of HOTS problems based on questions in mathematics textbook

The purpose of this research was to reconstruct HOTS questions using questions in mathematics textbooks. The study was conducted used a research and development method. The objects of research and development were questions in mathematics textbooks using in junior high school. The research procedure consisted of collecting and selecting textbooks in mathematics instruction, selecting the topic of the subject, identifying and selecting problems, and reconstructing HOTS items. The item reconstruction phase included expert judgment and field trials. HOTS problem reconstruction was carried out through the improvement of questions in the textbooks so that the answers were not unique; the solution required several mathematical concepts and the use of other knowledge. The results showed that questions in mathematics textbooks could be reconstructed as HOTS questions. HOTS problem reconstruction can be achieved by changing the problem in such a way that it does not have a single solution, using a variety of mathematical concepts and other knowledge.
