Abstract

This study aims to determine whether there is the effect of problem based learning model on students' ability in solving math problems students junior high school Negeri 1 Kupang. The sample in this research is VIID students of junior high school Negeri1 Kupang which is 24 students. Data used in this research is pretest and posttest data from experiment class by using of problem based learning model. The data obtained were analyzed using SPSS version 22. Prior to hypothesis testing, prerequisite tests were tested for normality for pretest and posttest data. From the analysis results for pretest data obtained Asymp.Sig. (2-tailed) = 0.073 > 0.05 and Dcount = 0.170<0.269 = Dtable. Because it meets the testing criteria data pretest is normally distributed. While the data obtained posttest Asymp.Sig value. (2-tailed) = 0,200> 0,05 and Dcount = 0,132<0,269 = Dtable. This data also meets the test criteria so that posttest data is normally distributed. Hypothesis testing using paired sample test, after analyzed data obtained by Asymp value. Sig. (2-tailed) = 0,000 <0,05 and tcount = 33, 912 > 2.0686 = ttable then H0 is rejected and Ha accepted, meaning there is a significant the effect on problem based learning model on students' ability in solving math problems students junior high school Negeri1 Kupang. The results of this study indicate that the tools of former materials have an effect on to the achievement of learning mathematics. Therefore, the authors suggest for teachers to use problem based learning model in class according to the material to be taught.
