Problem-based learning model to improve mathematical reasoning ability

Abstract

Reasoning ability is very important to note because it is able to train students' thinking activities to be able to solve mathematical problems. This ability is also a benchmark in determining student achievement in the field of mathematics, one of which is in the international event TIMSS and PISA. However, the competitiveness of Indonesian students is still very low compared to other countries. This can be caused by the lack of giving questions that practice the ability of reasoning by the teacher. Therefore, there is a need for improvement in the process of learning mathematics. In the learning process, students should be given the opportunity to explore all their potential. The teacher can offer problems that are able to train and develop mathematical reasoning abilities. Problem-based learning is problem-centered learning. Problems given can be related to real-life students and can practice the ability to reason and solve mathematical problems.
