Abstract

This study aims to describe the numeracy ability of students at the cognitive level of reasoning grade VIII State Junior High School 5 Rambah Hilir in solving algebraic domain numeracy problems. This study uses a qualitative approach with a descriptive type. The subjects in this study are students in grades VIII-3 of State Junior High School 5 Rambah Hilir which totals 23 students. Then 6 students with qualifications 2 students with high numeracy skills, 2 students with moderate numeracy skills and 2 students with low numeracy skills were selected as interview subjects. The technique of checking the validity of the data uses triangulation techniques. The results of the study showed that the numeracy ability of students at the cognitive level of reasoning at State Junior High School 5 Rambah Hilir, namely students with a high level of numeracy ability at the cognitive level of reasoning, were able to meet the three indicators of numeracy ability at the cognitive level of reasoning, namely namely analyzing data and information, evaluating, and inferring. Students with a level of numeracy ability at the cognitive level of moderate reasoning are only able to meet two indicators of numeracy ability at the cognitive level of reasoning, namely analyzing data and information, and evaluating. Students with a low level of numeracy ability at the cognitive level of reasoning are only able to meet one indicator of numeracy ability at the cognitive level of reasoning, namely analyzing data and information.

Abstract

This study aims to describe the ability of students' mathematical representation on the material of a two-variable linear equation system reviewed from Self Efficacy. The type of research used is qualitative research with descriptive methods. The sampling technique used is purposive sampling. The data collection technique used a test of students' mathematical representation ability, self-efficacy questionnaire, semi-structured interviews, and documentation. The data obtained was then analyzed in 3 stages, namely data reduction, data presentation and conclusion drawn. The results showed that students with a high self-efficacy category met all three indicators of mathematical representation ability, namely using visual representations to solve problems, solving problems by involving mathematical expressions and writing Steps to solve mathematical problems with words. Students with the category of self-efficacy Moderate meet two indicators of mathematical representation ability, namely using visual representation to solve problems and solve problems by involving mathematical expressions. Students with low self-efficacy meet one indicator of mathematical representation ability, namely solving problems by involving mathematical expressions.

Abstract

Minimum competency assessment is a basic competency that all students need to be able to develop their own abilities and play an active role in society in positive activities. Minimum competency assessment aims to measure students' cognitive learning outcomes which include reading literacy and numeracy competencies. This study aims to determine the types of errors made by students in solving algebraic domain numeracy problems based on the kastolan theory, namely: (1) conceptual errors, (2) procedural errors, (3) technical errors. The research that has been conducted is a qualitative descriptive study with a research instrument of three AKM type algebra essay questions on 26 class VIII 3 students at SMP N 1 Tambusai. The results obtained based on the results of student answer sheets include: (1) conceptual errors of 30.76%, procedural errors of 38.46%, and technical errors of 32.05%. It can be concluded that the mistakes that students often make are procedural errors. The results of this study provide an overview of the various errors made by students in solving algebraic domain AKM problems, so that they can determine follow-up actions so that students' numeracy skills become better.
