Meningkatkan Penalaran Dan Kemampuan Komunikasi Matematika Menggunakan Model Pembelajaran Treffinger Materi Persamaan Dan Pertidaksamaan Linear Satu Variabel

Abstract

The purpose of this study is to describe an increase in communication and mathematical reasoning skills students after learning with the learning model Treffinger Inequality Matter Linear Equations and One Variable. Research carried out by using basic methods of observation and field notes as well as the test methods and documentation aids. Analysis use reduction, presentation, and conclusion. Subjects are student VIIA of SMP Negeri 2 Wuryantoro many as 36 students. The study was conducted two rounds, the first round of the given strategy discussion, whereas in the second round with the strategy discussions and presentations. The results of this study showed an increase in the indicatorindicator

reasoning and communication skills, namely: (1) the ability to answer questions that the teacher increased from 5.7% to 63.8%, (2) ability to provide feedback during the learning process takes place increased from 14 , 3% to 44.4%, and (3) the ability to make inferences from the results of the learning is done rose 5.7% to 52.8%. From the study it can be concluded that learning Treffinger of model can improve the ability of reasoning and communication skills math, students VIIA of SMP Negeri 2 Wuryantoro.
