Abstract

The ability of the mathematical representation is the ability to create a model of a problem into a new form of verbal, text, tables, or graphs. The research is a qualitative descriptive study aimed to systematically describe the capabilities of mathematical representation. Data collection techniques in this study conducted using tests such as about the description, the test is given to students of class IX in one of the Junior High School in the city of Cimahi with 37 students. The results showed that the ability of the mathematical representation of students on the material for the indicator congruence and similarity of words or text are at less qualification with the percentage of students average score of 43%. Indicators visual representation including sufficient qualification with the percentage of students average score of 60%. On the indicator equations or mathematical expressions including the qualification is very less with the average percentage score of 34.75%. Difficulties faced by students predominantly found in Question 2b, 4b with the kind of test containing indicator words or text and Question 4c with indicators equations or mathematical expressions.

Abstract

This research aims to look at the difference in the ability of mathematical creative thinking in students, through Realistic Mathematical Education learning or RME and through conventional learning. The research design used was an experiment, namely in the form of a test of the ability of creative thinking. The population in this study of Junior High School students throughout the country, namely in West Bandung Regency. Sample research VIII grade i.e. in one of the Junior High School in West Bandung chosen at random and selected class A (grade experiment) that uses learning Realistic Mathematics Education (RME) and class B (grade control) that uses regular or conventional learning. The research results showed that the p-value of 0.000 < critical limits. Thus, the ability of mathematical creative thinking of the students who got the learning with Realistic Mathematics Education better than the students who got conventional learning.
