Abstract

This research is motivated by the fact that numeracy skills are fundamental abilities that every student must possess. However, observations in the field indicate that students' mathematical abilities, particularly in the topic of systems of linear equations with two variables (SPLDV), are still relatively low. This study aims to describe students' numeracy skills, which are divided into three stages: (1) knowing, (2) applying, and (3) reasoning. The study involves 20 eighth-grade students as subjects. The method used is descriptive qualitative, with data collection techniques including tests, interviews, and documentation. Data analysis is conducted based on three levels of numeracy skills: high, medium, and low. The results show that students' computational abilities in the SPLDV material are generally low, with an average score of 33%. The implications of these findings highlight the need for the implementation of more varied and contextual teaching strategies to enhance students' computational skills. This research can serve as a foundation for teachers to provide further assistance to students facing difficulties, with an emphasis on improving overall computational abilities.

Abstract

The aim of this research is to analyze and describe the mathematical communication skills of junior high school students in relation and function material. The research subjects were 22 students of SMP Muhammadiyah 4 Pekanbaru class. The type of research is descriptive qualitative with data collection in the form of written tests and interviews. The written test was in the form of a description of 3 questions. Data analysis was done through data reduction, data presentation, and conclusion drawing. The results showed that students' overall mathematical communication skills were still low with an average of 23.48%. Students achieved indicator 1 (written text) by 28.41%, indicator 2 (drawing) by 35.23%, and indicator 3 (mathematical expressions) by 7.95%. Students' difficulties occurred when converting problem information into mathematical models, explaining the solution steps coherently, and using correct mathematical language. This was caused by limited prerequisite skills, low concept understanding, and poor writing skills.
