The design of this research was pretest posttest control group design. The population of this research was all students of grade 8th of SMPN 12 Bandarlampung in academic year of 2013/2014 that was distributed into nine classes. The samples of this research were students of VIII H and VIII I class who were taken by purposive sampling technique. The research data were obtained by test of mathematical reasoning skill and self-confidence scale. The conclusion of this research was the problem based learning could increase the student?s mathematical reasoning skill, but it couldn?t increase the student?s self confidence. Penelitian ini bertujuan untuk mengetahui peningkatan kemampuan penalaran matematis dan self-confidence siswa yang mengikuti pembelajaran berbasis masalah dibandingkan pembelajaran konvensional.
