Analysis of Critical Thinking Ability in Solving Linear Inequalities with One Variable Reviewed From a Mathematical Disposition

Abstrak

Abstract

This study aims to describe students' critical thinking skills in solving linear inequality problems with one variable in terms of mathematical disposition. This type of research is quantitative-qualitative research. The subjects in this study were three students selected from 31 students in class VIII-4 of SMP Negeri 4 Ambon with categories of high, medium, and low mathematical disposition. The results of the study showed that subject JA, with a high mathematical disposition showed that he could fulfil every indicator of critical thinking. Subject JFT, with a medium mathematical disposition category, showed that he could fulfil the critical thinking indicator on some questions and could not fulfil the critical thinking indicator on other questions. Meanwhile, subject JK, with a low mathematical disposition category, could only fulfil two indicators of critical thinking. Based on the percentage of the results of filling out the mathematical disposition questionnaire, the high mathematical disposition category is 41.94%, the moderate disposition category is 48.39%, and the low disposition category is 9.68%, which means that the largest percentage of mathematical disposition of class VIII-4 students is in the moderate mathematical disposition category.
