EFEKTIVITAS PENDEKATAN REALISTIC MATHEMATICS EDUCATION (RME) TERHADAP KEMAMPUAN PEMECAHAN MASALAH MATEMATIKA

Abstract

The ability to solve mathematical problems as one of the important skills for students who is also the goal of learning mathematics in the 2013 curriculum. The importance of problem solving skills is the basis for research objectives to
analyze the effectiveness of the Realistic Mathematics Education (RME) approach to the mathematical problem solving abilities of eighth grade students of SMP Negeri 23 Bandar Lampung, with research problems in the form of low mathematical problem solving abilities of students. This study uses an experimental method with a population of all eighth grade students of SMP Negeri
23 Bandar Lampung which consists of 9 classes with a total of 287 students, while the sample is taken 2 classes, namely as an experimental class that applies the RME approach and as a control class that applies the conventional approach. The sample was taken using the cluster random sampling technique. Measurement of research variables using a test in the form of an essay as many as 5 questions that have been tested for validity and reliability and declared as a good measuring tool. Hypothesis testing using parametric statistics in the form of t-test. The results of hypothesis testing show the value of t hit = 4.33 and at a significant level of 5% it is known that t daf = ????(1−????)= 1,67 means t hit > t daf so it can be concluded that the RME approach is effective in influencing students' mathematical problem solving abilities class VIII SMP Negeri 23 Bandar Lampung. This situation is also
seen from the average value of students' mathematical problem solving abilities where the experimental class has a higher average value of 77 and the control class has an average value of 61.
