The Differences In Students Mathematical Resolution Ability Assisted By Geogebra

The aim of this research to find out is there or no the differences of student’s mathematical problem solving ability between IMPROVE learning model and Two Stay-Two Stray learning model assisted by Geogebra. The method of research that used Quasi Experiment. The sampling technique using Cluster Sampling and obtained a sample of 68 students in the class X 43 Jakarta Senior High School in the second semester of the 2015/2016 academic year. Instrument of this research using mathematical problem solving ability test which has been tested validity, reliability, level of difficulty and distinguishing features. The requirements analysis test conducted this research are normality test and homogeneity test. Furthermore, hypothesis test obtained t_result for 2,09 with significance level 0,05. Based on the results of this research concluded that there is differences student’s mathematical problem solving ability between IMPROVE learning model and Two Stay-Two Stray learning model assisted by Geogebra’s software
