Inquiry Learning and Lesson Study Activities on Improving Mathematical Critical Thinking Ability of Madrasa Students

Learning mathematics requires students to always be active in the learning process because mathematics is a field of science that prioritizes high intellectual quality and not just knowledge that is informative and theoretical. One of the intellectual qualities can be seen from the ability to think critically and is one of the needs of students in learning mathematics. But the fact is that currently, learning is still dominated by the lecture method and rarely facilitates students to develop their critical thinking skills. Appropriate teaching and learning strategies approaches, and models are needed to train mathematical abilities. Therefore, teachers are expected to be able to determine the right strategy so that learning objectives are more optimal. In this study, researchers analyzed how the results after applying inquiry learning strategies and Lesson Study activities affected students' critical thinking skills. The study population was students of class XI Madrasah Aliyah Mu'allimat NW Pancor, and the sample was determined by purposive sampling technique as many as 38 students. Research data were collected using documentation, questionnaires, observation sheets, and math substance tests. This research was conducted through four Lesson Study cycles. After carrying out this process, it was found that there were positive results from the application of inquiry learning strategies and Lesson Study activities to improve student's critical thinking skills in mathematics.
