In the conventional learning of mathematics, generally learners are not given enough opportunity to develop their reasoning ability because of the teacher's excessive concentration on mathematical activities which are algorithmic and mechanical while abilities in problem-solving, critical and creative thinking, and communicating are important for learners to possess on the face of such a global information era as that currently going on. The problem-based learning (or PBL, for short) carried out in the research this article is about is one of the approaches to the learning of mathematics facilitating learners in learning through problem-solving activities. By means of such mathematical activities, learners are urged to make observations, explorations, investigations, and inquiries in solving mathematical problems. With teacher guidance, learners are made to feel demanded to ask questions and give arguments through a process of in-group interaction, negotiation, and reflection so that they could formulate conjectures and conclusions. The research this article is about employed the procedure of collaborative classroom action research conducted through the implementation of problem-based learning and focused on improving the mathematical reasoning ability of junior high school students. The research subjects were forty-six students of Grade 2B at SMP Negeri 22 Bandung, a state junior high school. The instruments employed in the research were tests on reasoning ability, questionnaires, observation sheets, students' diaries/journals, and interview pointers. The research results indicate that the learning
