Abstract
This paper presents the findings of a quasi-experimental with pre-test-post-test design and control group that aims to assess students' critical mathematical thinking skills and character through realistic mathematics education (RME) culture-based. Subjects of this study were 106 junior high school students from two low and medium schools level in Ambon. The instruments of the study are: students' early math skills test, critical thinking skills mathematical test and perception scale of students' character. Data was analyzed by using t-test and Anova. The study found that: 1) Achievements and enhancement of students' critical mathematical thinking skills who were treated with by realistic mathematics education is better then students' skills were treated by conventional mathematics education. The differences are considered to: a) overall students, b) the level of early math skills, and c) schools' level; 2) Quality of students' character who were treated by realistic mathematics education is better then students' character who were treated by conventional mathematics education The differences are considered to: a) overall students, b) the level of early math skills, and c) schools' level Keywords : Critical Thinking, Students' Character, Realistic Mathematics Education Culture-Based
Highlights
PISA study (Balitbang-Depdiknas, 2009) reported that students' mathematics learning achievement of junior high school students in Indonesia is not encouraging
Subsequent analysis, the findings obtained achievements and enhancement of students’ critical thinking skills mathematical from low school level who have been using Realistic Mathematics Education (RME) (59.36 and 0.45) better than the achievement and enhancement of students’ critical thinking skills mathematical from medium school level who have been using Conventional Mathematics Education (52.69 and 0.39) These findings indicate that RME culture-based variable \provide a better role than the role of school level to achievement and improving students' critical thinking skills mathematical
In term of overall student, school level and early math skills, students’ critical thinking skills who have been using RME is better than students skills who have been using Conventional Mathematics Education
Summary
PISA study (Balitbang-Depdiknas, 2009) reported that students' mathematics learning achievement of junior high school students in Indonesia is not encouraging. As the implications of the above cases, Marpaung (2001) suggests that teachers need to pay attention to learning math-oriented students' understanding. Some of the results of the above studies reported that critical thinking skills mathematics of junior high school students who obtain mathematical innovative learning better than critical thinking skills students who obtain conventional learning. These findings support the suggestions to need learning which implemented to train the students think. A side from being a method of learning mathematics, RME
