Abstract

Huruf-huruf aljabar biasanya hanya dikenal sebagai variabel oleh siswa, padahal huruf-huruf aljabar ini memiliki ragam makna pada suatu permasalahan matematis. Pada penelitian ini bertujuan untuk menyelidiki interpretasi siswa terhadap makna dari huruf-huruf aljabar dalam menyelesaikan masalah matematis dengan perspektif siswa dalam masa transisi berpikir aritmetik ke berpikir aljabar. Penelitian yang digunakan pada penelitian kualitatif dengan jenis penelitian pada penelitian fenomenologi. Partisipan penelitian ini merupakan 18 siswa SMP yang diambil dari tiga sekolah yang terdapat di Riau. Teknik pengumpul data pada penelitian ini adalah dokumen lembar kerja siswa, wawancara yang direkam secara audio dan video dan catatan lapangan penelitian. Berdasarkan temuan penelitian pada siswa kelas VII tersebut, ditemukan bahwa siswa menginterpretasikan huruf-huruf aljabar hanya sebagai pengganti dari bilangan tertentu. Siswa menjadikan huruf-huruf aljabar sebatas pengganti bilangan asli dibandingkan sebagai bilangan yang diperumum. Huruf-huruf aljabar yang dikaitkan dengan ekspresi aljabar dan operasi aljabar serta persamaan aljabar memberikan kesulitan bagi siswa dalam menyelesaikan masalah tersebut. Hal ini disebabkan siswa belum mampu melihat bahwa huruf-huruf aljabar tersebut merupakan serangkaian konsep dasar aljabar generalized numbers bahkan pada konsep variabel. Algebraic letters are usually only known as variables by students, even though these algebraic letters have a variety of meanings in a mathematical problem. This study aims to investigate students' interpretation of the meaning of algebraic letters in solving mathematical problems from the perspective of students in the transition period from arithmetic to algebraic thinking. The type of research used in qualitative research is phenomenological research. The participants of this study were 18 junior high school students taken from three schools in Riau. Data collection techniques in this study were student worksheet documents, audio- and video-recorded interviews, and research field notes. Based on the research findings on the seventh-grade students, it was found that students interpret algebraic letters only as a substitute for certain numbers. Students make algebraic letters as a substitute for natural numbers rather than as generalized numbers. Algebraic letters associated with algebraic expressions, algebraic operations, and algebraic equations deliver difficulties for students in solving these problems. This is because students have not been able to see that these algebraic letters are a series of basic concepts of generalized numbers in algebra, even on the concept of variables.

Abstract

This study aims to examine the mathematical problem-solving abilities of seventh-grade junior high school students on the topic of integers. A descriptive qualitative approach was employed, involving 36 students from a public junior high school in Kampar Regency. Data were collected through three specially designed written test items and semi-structured interviews to explore students' thinking processes. The results show that students’ abilities can be categorized into three levels: high (13.89%), moderate (69.44%), and low (16.67%). Students in the high category demonstrated systematic steps and critical reflection. Those in the moderate category generally understood the problems but often made mistakes in selecting and applying appropriate strategies and showed a lack of accuracy. Students in the low category struggled at almost every stage of problem-solving. Contributing factors include understanding of basic mathematical concepts, strategy selection, accuracy, and clarity of the problem statements. The study recommends the use of contextual and reflective learning approaches to enhance students' mathematical problem-solving skills. Keywords: Problem-solving, Integritas, Mathematics, Contextual learning.

Abstract

Low level of students’ learning motivation and numeracy skills in the topic of the System of Linear Equations in Three Variables (SLETV) remains a challenge in mathematics learning at schools. Many students experience difficulties in understanding SLETV concepts because the instructional delivery tends to be abstract and less engaging; therefore, a learning approach that can enhance students’ readiness and interest prior to face-to-face classroom activities is required. This study aimed to examine the effect of the Flipped Classroom model assisted by Canva videos on students’ learning motivation and numeracy skills. This research employed a quasi-experimental method with a Nonequivalent Control Group Design, involving two classes selected through purposive sampling: an experimental class that received Flipped Classroom instruction and a control class that followed conventional learning. Data were collected through a learning motivation questionnaire and a numeracy skills test administered after the treatment. Data analysis was conducted using descriptive statistics and an independent samples t-test to determine differences in learning outcomes between the two groups. The results showed that the average learning motivation score of students in the experimental class reached 69.86, which was higher than that of the control class at 58.97. Meanwhile, the numeracy skills of the experimental class achieved an average score of 88.66, compared to 63.95 in the control class. The t-test results indicated a significance value of 0.000 for both variables, demonstrating a statistically significant difference between the two classes. These findings indicate that the Flipped Classroom model assisted by Canva videos effectively enhances students’ learning readiness, promotes active engagement during the learning process, and facilitates a better understanding of numerical concepts compared to conventional learning. This model can be considered an alternative instructional strategy to support the improvement of students’ learning motivation and numeracy skills.

Abstract

The aim of this study is to develop a mathematics learning module based on the RBL model that incorporates Islamic values, specifically for the topic of compound probability. Additionally, the study seeks to determine whether the module is valid and effective in enhancing students' conceptual understanding. This study was motivated by students' low conceptual understanding of compound probability and the limited availability of independent, Islamic value-integrated learning materials based on RBL syntax. This study employs a Research and Development (R&D) approach based on the 4-D model, which comprises the stages of Define, Design, Develop, and Disseminate. The research subjects consisted of 22 students from class XI at MA IBS Riau. After data were collected using expert validation sheets and pre-test and post-test scores, a descriptive quantitative method was used to analyze them. The results showed that the developed module achieved an overall validity score of 84.29% (categorized as "very valid"). The effectiveness test yielded an average N-Gain score of 0.6914 (moderate category), with 77.3% of students achieving moderate-to-high learning gains and a classical mastery level of 54.55%. These results indicate that the RBL-based mathematics learning module, which incorporates Islamic values ​​into the topic of compound event probability, possesses a satisfactory level of validity and effectiveness. They also demonstrate its suitability as an alternative resource for independent learning, particularly in Islamic boarding schools
