Abstract

This research examined how effective the Realistic Mathematics Education (RME) modelo was when supported by GeoGebra and an Interactive Flat Panel (IFP) in strengthening students' mathematical problem-solving ability on algebraic function limits. A quasi-experimental Nonequivalent Control Group Design was applied to 30 experimental-class students and 35 control-class students of SMA Negeri 1 Kampar Timur, selected by purposive sampling. An essay test of problem-solving ability served as the data collection instrument, and the data were examined through normality, homogeneity, t-test, Mann-Whitney U, and N-Gain analyses. Since some of the data departed from normality, the Mann-Whitney U test was used alongside the t-test. Both tests produced a significance value of 0.000 (< 0.05). The mean N-Gain reached 0.77 (high category) in the experimental group but only 0.06 (low category) in the control group, and classical mastery was 90.00% against 17.14%. These findings showed that RME supported by GeoGebra and IFP was effective in improving students' problem-solving ability on algebraic function limits.
