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