Abstract

This study aims to describe the problem-solving ability profile of junior high school students in class VIII in terms of cognitive styles from Field Independent and Field Dependent cognitive styles. The research method used is descriptive qualitative. This research was conducted in a junior high school in Belu district, in August 2023. The participants in this study were three FD cognitive style students and three FI cognitive style students. The instrument is a set of questions from the problem-solving ability test, the Group Embedded Figure Test, and interviews. The findings show that the profile of students' abilities in solving mathematical problems with the FI cognitive style is categorized as good in understanding the problem, planning the solution, implementing the solution plan, and checking again. Meanwhile, the ability of students with the FD cognitive style is categorized as sufficient at the stage of understanding the problem and planning a solution, and categorized as lacking at the stage of carrying out the settlement plan and looking back.

Abstract

The aim of this study is to describe the profile of social arithmetic problem-solving abilities of Grade VII students in one of the junior high schools in the TTU Regency. The type of research used in this study is a qualitative description, and the subjects of the study were 17 students, of whom six were selected for interviews. The six students included two high-ability, two moderate-ability, and two low-ability students. The data analysis model used in this study is the interactive data analysis model developed by Miles and Huberman. The results of the study show that: 1) Students in the high-ability category were able to fulfill all indicators of problem-solving, including understanding the problem, devising a plan, carrying out the plan, and looking back; 2) Students in the moderate-ability category were able to meet the indicators of understand the problem, devising a plan, and carry out the plan, but were unable to meet the indicator of look back; 3) Students with low abilities were able to fulfill the steps of understanding the problem and devising a plan, but were unable to fulfill the steps of carrying out the plan and look back.

Abstract

This study aims to improve students' problem-solving abilities through a constructivist approach. This study uses quantitative methods in the form of pre-experimental. This research was carried out in the even semester of the 2022/2023 academic year This research design used one group pretest and post-test. The participants of this study were 17 grade X students of one of the high schools in North Central Timor district. Research instruments in the form of problem-solving ability tests. Before conducting data analysis, a prerequisite test is first carried out, namely a normality test using the SPSS-assisted Shapiro-Wilk test, and the results obtained that the data is normally distributed. Test the hypothesis using a one-sample t-test and a paired sample t-test. The results showed that students who learned using the constructivist approach achieved minimal completeness and there was an increase in the mathematical problem-solving ability of students who learned through the constructivism approach. Learning with a constructivist approach can facilitate the problem-solving ability of high school students. Therefore, it is recommended that advanced researchers in order to be able to apply constructivist approaches to other mathematical abilities
