Abstract

This research is a quasi-experimental study aiming at analyzing the role of the metacognitive guidance approach in order to improve high-school students' critical thinking skills by applying Non-Equivalent Control Group Design. This study involved high school students in one of the high schools in the city of Cimahi. In this study, the pretest for mathematical critical thinking skills is administered to two classes of students of control and experiment groups. The experimental group uses the metacognitive guidance approach assisted by GeoGebra software, whereas the control group uses the conventional method. Both classes receive the same hours of study, mathematics teacher as well as mathematics contents. The researcher conducted observations only in the experimental class. At the end of the treatment, a post-test for the two groups was carried out regarding students’ mathematical critical thinking skills included processing the results of the test, namely the data. After this research has been carried out, the next step is to analyze the data and draw conclusions of the research. In analyzing the data, it is categorized into three levels, namely high, medium and low abilities. The data is analyzed by means of t-test to test the difference of two means of students’ critical thinking ability. Data analysis was performed using the SPSS software. The analysis shows that there is a significant difference in mathematics critical thinking ability between the two groups of students.

Highlights

Mathematics is one of the most important subjects to be mastered because almost every level of mathematics education is studied
133 compared to normal learning seen from KBKM are students' initial mathematics ability (KAM) and examine whether there is an interaction between CBC and MCG approaches
From the results of the study, it was found that all indicators of mathematical critical thinking ability had increased both in the experimental class and in the control class where the increase in mathematical critical thinking ability of students who were given MCG learning was higher than students who were given PB learning

Summary

Introduction

Mathematics is one of the most important subjects to be mastered because almost every level of mathematics education is studied. Mathematical critical thinking is the basis of the process of thinking to analyze arguments and bring ideas to each meaning to develop logical thinking patterns. It was expressed by (Marlina & Harahap, 2018) that mathematical critical thinking is a process that leads to drawing conclusions about what we have to believe and actions to be taken. According to (Sari, Eriani, Audina, & Setiawan, 2019), mathematical critical thinking is an activity of thinking about ideas or ideas related to a given concept or problem.
