The purpose of this study was to examine differences in overall mathematical reasoning abilities and based on indicators among students who received problem based learning with students who obtained discovery learning based on early math skills. This study was a quasi experimental research, with the study population was all students of class XI SMK Laksamana Martadinata consisting of twenty classes. By purposive sampling, two classes were chosen, with experimental class 1were given problem-based learning treatment and experiment class 2 were given discovery learning treatment. The instrument of mathematical reasoning ability, the ability of early mathematics and observation sheet were stated to have fulfilled the validity requirements of the contents, and the reliability coefficients of 0.740 and 0.830 respectively. Data analysis of mathematical reasoning ability was done by analysis of covariance (ANAKOVA). The results showed that there were significant differences in mathematical reasoning ability both overall and per indicator between students who were given problem-based learning with students who were given discovery learning, with problem-based learning showed better results. The results suggest that problem-based learning is an alternative to improving the ability of mathematical reasoning.
