Abstract

Representation is a tool to solve a problem in the form of interpretation of what students think of a problem in the form of visual, verbal, and algebraic or symbolic representations. Solving non-routine problems in mathematics learning requires high order thinking skills (HOTS). Solving student problems, both routine and non-routine problems can be influenced by the ability of students to process existing problems into a challenge that must be passed, which is called Adversity Quotient. The purpose of this study was to describe the process of visual to verbal mathematical representation of junior high school students in solving HOTS questions in terms of the adversity quotient. The research uses a qualitative approach, the type of research used in this research is descriptive qualitative research. The data obtained in the form of written test results data, questionnaire results data and interview data will be submitted in written or oral form in narrative form. The instruments used are in the form of tests and questionnaires. The result show that the subject representation process with the adversity quotient level for the climber category has met the representation process indicators well in the three HOTS questions that were worked on. Subjects with the adversity quotient level in the camper category have not been able to meet the indicators of the representation process in the HOTS problem of creating.

Abstract

This study aims to examine students' computational thinking skills in solving contextual problems in the matter of a system of two-variable linear equations. This type of research uses descriptive qualitative approach. The subjects used in this study were 25 class VIII students of State Middle School in the 2022/2023 academic year on SPLDV material (System of Two-Variable Linear Equations). Data collection techniques and instruments in this study were written tests and interviews. Data analysis was carried out by first classifying the data, then presenting the data and ending by concluding the results of computational thinking indicators. The results showed that the percentage of students' computational thinking aspects, namely the decomposition aspect, was 70.30% in the good category, pattern recognition 58.63% sufficient category, abstraction 58.30% sufficient category, and thinking algorithm 50.47% sufficient category. So that students' computational thinking skills are included in the sufficient category. Meanwhile, based on the categorization of high-level students they have done well. However, there were several steps that were missed and not written down in the answer sheets, such as the decomposition and pattern recognition aspects which were not carried out properly. For the medium category, all stages of computational thinking have been carried out very well starting from decomposition, pattern recognition, abstraction, and thinking algorithms. For the low category, this category has not been able to carry out the stages of computational thinking properly.
