Abstract

Kemampuan literasi merupakan salah satu kemampuan dasar yang harus dimiliki siswa sebagai prasyarat kecakapan hidup abad ke-21. Menurut World Economic Forum pada tahun 2015, ada enam literasi dasar yang harus dimiliki siswa, salah satunya adalah kemampuan literasi numerasi. Literasi numerasi yang baik akan melahirkan siswa yang terampil menggunakan matematika dengan percaya diri di pembelajaran sekolah maupun di kehidupan sehari-hari. Oleh karena itu kemampuan literasi numerasi sangat penting dimiliki siswa. Tujuan penelitian ini adalah untuk mengetahui tingkat kemampuan literasi numerasi siswa SMP dengan menggunakan indikator kemampuan literasi numerasi. Pendekatan kualitatif deskriptif digunakan dalam penelitian ini. Subjek dalam penelitian adalah 19 siswa kelas VIII di salah satu SMP Swasta di Kabupaten Rokan Hulu. Teknik analisis data Miles dan Huberman digunakan pada penelitian ini. Dari hasil penelitian diperoleh nilai tes literasi numerasi siswa masih terletak di interval ≤40 yang termasuk kategori rendah. Hasil analisis menunjukkan bahwa siswa belum sepenuhnya memahami apa yang dimaksud soal. Indikator yang paling rendah yaitu indikator ketiga yaitu menafsirkan hasil analisis untuk memprediksi dan mengambil keputusan. Hal ini dapat menjadi pertimbangan bagi guru agar dapat mengembangkan kemampuan literasi numerasi siswa dalam pembelajaran di kelas.

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

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.

Abstract

Purpose – This study aims to investigate the effectiveness of puzzle media in improving mathematics learning outcomes on the topic of fractions among seventh-grade students at SMP IT Lentera. The research is motivated by the difficulties students often face in understanding fractions, which are considered abstract and challenging. Methodology – The study employed a Classroom Action Research (CAR) approach, conducted in two cycles consisting of planning, implementation, observation, and reflection. The participants were 30 seventh-grade students. Data were collected through tests and observations, and analyzed descriptively to examine learning outcomes and mastery levels. Findings – The results showed a significant improvement in student achievement. The average score increased from 60 in the pre-cycle to 72 in Cycle I and 82 in Cycle II. Classical mastery also rose from 40% to 66.7% and finally to 86.7%. These findings indicate that puzzle media is effective in making abstract mathematical concepts more understandable and engaging. Novelty – The originality of this study lies in the application of puzzle-based learning strategies to the teaching of fractions, which are usually perceived as difficult. Significance – The study provides practical implications for teachers seeking innovative strategies to enhance student engagement and achievement in mathematics learning.

Abstract

This study aims to determine the effect of the cooperative learning model, Student Facilitator and Explaining, on students' mathematical problem-solving abilities in Grade IX of SMP Tiga Hati Kepenuhan Hulu. The research employed a quantitative approach with a quasi-experimental design. The study subjects were Grade IX students divided into two groups: the experimental group, which was taught using the Student Facilitator and Explaining model, and the control group, which was trained using a conventional learning model. Data were collected through a mathematical problem-solving ability test. The hypothesis testing results showed that the t-value (2.37) was greater than the t-table value (2.12) at a significance level of α = 0.05. Therefore, H₀ was rejected and H₁ was accepted. This indicates a significant effect of the Student Facilitator and Explaining cooperative learning model on students’ mathematical problem-solving abilities
