PENGARUH MODEL MISSOURI MATHEMATICS PROJECT (MMP) TERHADAP PENINGKATAN KEMAMPUAN PEMECAHAN MASALAH MATEMATIS SISWA

Abstract

The low mathematical problem solving ability of students was caused by the monotonous learning procces, students tend to become passive during learning and lack motivation to learn mathematics. As a result, students had difficulty solving math problems. Therefore, new innovations were needed in learning mathematics that were more effectuve to improve the problem solving ability. This study aimed to determine the effect of Missouri Mathematics Project (MMP) learning model students’ mathematical problem solving skills and compare it with conventional learning models. This study was conducted at MTs Al-Rahmah, Serang City. The type of study used was True Eksperimental Design using PretestPosttest Control Group. The Samples size was 60 students from the total population of class VIII MTs Al-Rahmah which was taken randomly using sample random sampling technique. The sample was divided into two groups, namely the experimental group using Missouri Mathematics Project (MMP) learning model and the control group using conventional learning model. Data collection techniques used tests (pretest and posttest) to determine students’ mathematical problem solving skills. The data were analyzed using a simple linear regression test and an independent sample t-test. The results of this study showed that, (1) there was a significant effect of Missouri Mathematics Project (MMP) learning model on students’ mathematical problem solving skills with a tcount value of 21,498 > ttable = 2,048 which means Ho was rejected and (2) there was a significant difference in improving of mathematical problem solving skills between students used Missouri Mathematics Project (MMP) learning model and students used conventional learning model with a tcount value of 6,2454 > ttable = 2,048 which means Ho is rejected.
