Abstract

This study aims to describe the profile of students' mathematical problem solving in terms of gender differences. This type of research is descriptive research using a qualitative approach. The subjects of this study were students of class X SMA which consisted of one male student and one female student with high mathematical ability. The data were collected using the problem solving task method and the interview method. The results of this study include, female subjects can express verbally or in writing the information contained in the given task, the subject can develop a problem-solving plan by making an example to make a mathematical model in the form of an equation and want to solve it using a combined method, the subject carries out the settlement plan is in accordance with the problem solving plan, and the subject does not re-examine the problem solving because he does not understand how. While the male subject can verbally state the information contained in the given task, the subject can develop a problem-solving plan by making an example to make a mathematical model in the form of an equation and want to solve it using the combined method, the subject carries out a settlement plan according to the plan. problem solving, and the subject did not re-examine the problem solving because they did not know how.

Abstract

This study aimed to obtain a description of the critical thinking of students in class VII SMP in solving problems on the material of build flat triangle. This type of research is descriptive-qualitative with a case study approach. In this study, three students were selected, each of whom had high, medium and low mathematical abilities. Data collection techniques in this study by providing questions about the triangle material and interviews. The triangle material was chosen because it can trigger students to use their higher-order thinking skills. The results of this study indicate that the critical thinking profile of students in class VII of SMP Negeri 1 Mepanga in solving problems on the material of build flat triangle is as follows, the critical thinking profile of students with high mathematical abilities (PM) includes, providing simple explanations, building basic skills, solving skills problem and conclude, the critical thinking profile of students with moderate mathematical ability (SR) includes, providing simple explanations, problem solving and concluding abilities and the critical thinking profile of students with low mathematical ability (AL) only provides a simple explanation.
