The Differences of Realization Ability between Students’ Learning Model Problem Based Discovery Learning Model in Smk Private Laksamana Martadinata Medan

Abstract

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.
