Abstract

his research is a qualitative research that aims to analyze the understanding of mathematical concepts of students of one of the yunior high school in Kupang city in problem solving on the material system of two-variable linear equations. The subjects in this study were three students of class VIII who had high ability, medium ability, and low ability. The selection of subjects were based UTS results and discussions with mathematics teacher. Data collected in the form of data on the results of problem solving tasks and the results of interviews based on indicators of understanding of the concept. Data analysis includes data reduction, data presentation, and drawing conclusions. Checking the validity of the data using time triangulation. After the data is presented and analyzed, it can be concluded that (1) Students with high ability results are able to solve the given problems and meet the indicators of the ability to understand concepts based on APOS theory. (2) Students with medium ability results are fulfilling the ability to understand concepts based on APOS theory. (3) While students with low ability results do not meet the indicators of the ability to understand concepts based on APOS theory.

Abstract

The purpose of this study was to determine the profile of students' perceptions of the concept of set material in seventh grade students of junior high school. The type of research used is descriptive qualitative. The subjects in this study were two seventh grade students of one junior high school in Kupang City with a high level of ability. Data collection is done by providing problem solving tasks (TPM), interviews and triangulation. Data analysis techniques used are data reduction, data presentation and conclusion drawing. In the first indicator, absorption, the results of the study show that the JW and VO subjects can mention information that is known in the TPM problem and mention what is asked in the matter of the TPM. In the second indicator, understanding or understanding, JW and VO subjects can understand how to solve TPM problems and mention the knowledge used to solve TPM problems. In the third indicator, evaluation or assessment, JW and VO subjects can solve problems and are able to explain the steps in solving TPM problems. Thus it can be concluded that both of subjects are able to fulfill all three indicators of perception
