Developing HOTS-based Model to Improve Mathematical Problem Solving Skill of Elementary School Teacher Education (PGSD) Students

Abstract

The purpose of this development research is to produce Higher Order Thinking Skill (HOTS)-based pre-service training model for students of PGSD Study Program of STKIP Muhammadiyah Blora who take Mathematics I courses. The teaching materials are in the form of HOTS-based teaching materials and evaluation questions to measure students' mathematical problem solving abilities. Teaching materials developed meet valid and effective criteria. This type of research is development research following Borg and Gall procedures. This research leads to the improvement of students' mathematical problem solving abilities after applying Mathematics based on Higher Order Thinking. In addition, through this teaching material, students become accustomed to high-level thinking so that they are able to solve any mathematical problems given even the average student's mathematical problem-solving ability was increased from 57.50 to 87.90. Thus, the development of HOTS-based mathematics learning modules can improve students' mathematical problem solving abilities.
