Abstract

Technology plays a crucial role in enhancing students' interest and understanding, particularly at the elementary school level. Therefore, students from the Faculty of Teacher Training and Education at the University of Mataram, participating in the 8th cohort of the Kampus Mengajar program and placed at SDN 04 Kuranji, developed the "Play with Quizizz" program. This article explores the implementation of Quizizz as a tool for teaching fifth-grade students at SDN 4 Kuranji using English. The program aimed to improve vocabulary acquisition, boost students' motivation to learn, and assist teachers in creating an interactive and engaging learning environment. The community service initiative involved several stages, including planning, implementation, and evaluation or refinement. The results demonstrated an increase in students' classroom engagement, as well as improvements in vocabulary and grammar comprehension. This article recommends the use of Quizizz as an innovative alternative learning medium, which can also be applied to other subjects to enhance the overall quality of education.

Abstract

This study aims to determine the effect of the Team Game Tournament (TGT) type cooperative learning model on the mathematical communication skills of 8th-grade students at SMPN 6 Masbagik. The research employed a quantitative approach using a true experimental method with a posttest only control group design. The population consisted of all 8th-grade students at SMPN 6 Masbagik in the 2024/2025 academic year, totaling 76 students. The sample was selected using a cluster random sampling technique, with two classes selected from three, namely classes VIIIA and VIIIB, each consisting of 26 students. The two classes received different treatments: class VIIIA as the experimental class using the TGT learning model, and class VIIIB as the control class using conventional learning. Data were collected through a mathematical communication skills test and observation. Data analysis included normality and homogeneity tests, hypothesis testing using the Independent Sample t-Test, and an effect size test. The results showed that the average posttest score in the experimental class was 69.5, while the control class scored 55. The t-test result showed a t-count of 4.434 > t-table 2.008, indicating a significant difference. The effect size result of 1.09 falls into the large category. In conclusion, the TGT model significantly affects students' mathematical communication skills.

Abstract

This study aims to analyze students' errors in solving Ordinary Differential Equations (ODE) problems based on the SOLO taxonomy (Structure of the Observed Learning Outcome). This qualitative descriptive research involved 29 students from the Mathematics Education Study Program at the University of Mataram. Data were collected through essay tests and interviews, then analyzed using the SOLO taxonomy classification and error types based on the framework by Subanji and Mulyoto. The results show that most students were at the pre-structural, uni-structural, and multi-structural cognitive levels, with a dominance of conceptual and technical errors. Common mistakes included the use of incorrect formulas, errors in algebraic manipulation, and weak fundamental calculus skills. A lack of understanding of prerequisite concepts such as algebra and calculus was identified as the main factor contributing to these errors. These findings highlight the importance of strengthening basic concepts and implementing learning strategies based on the SOLO taxonomy to improve students' understanding of ODE topics

Abstract

Duality in linear programming is an essential concept in optimization-based decision making. However, many undergraduate students still struggle to understand and solve duality problems, especially when converting primal to dual models and interpreting their results. This study aimed to explore the learning strategies used by fifth-semester students in solving duality problems. A qualitative case study approach was employed, involving 36 students from a mathematics education program. Data were collected through classroom observations, open-ended tasks, reflective writing, and interviews, and analyzed thematically. The findings revealed that most students (52.8%) used procedural repetition strategies, while others adopted conceptual elaboration (30.6%) and organizational strategies (16.6%). Students who used elaboration and organizational strategies demonstrated deeper conceptual understanding and greater problem-solving flexibility. These results suggest that procedural approaches still dominate, and instructional efforts should focus on fostering more reflective and meaningful learning strategies among students.

Abstract

Fraction sense is a critical aspect of number sense, particularly for prospective mathematics teachers. This study aims to describe students’ fraction sense from two main perspectives: visualization and estimation strategies. The study employed a qualitative descriptive method involving 80 fourth-year mathematics education students. Data were collected through a fraction sense test and semi-structured interviews. The findings indicate that students’ overall fraction sense was moderate, with an average score of 37.2. Students demonstrated higher performance in estimation strategies (68%) compared to visual representation tasks (32%). Many students struggled to interpret visual fraction models, especially when presented in unfamiliar forms such as non-standard diagrams or number lines. The results suggest that students' thinking remains procedural and lacks conceptual flexibility. Therefore, it is recommended that visual representation be more explicitly integrated into teaching practices as a tool to support estimation and foster meaningful fraction sense.

Abstract

Penelitian ini bertujuan untuk mengetahui pengalaman mahasiswa pendidikan matematika dalam menggunakan ChatGPT sebagai alat bantu dalam menyusun program MATLAB pada pembelajaran Komputer Matematika. Penelitian ini menggunakan pendekatan deskriptif kualitatif dengan melibatkan empat mahasiswa yang bekerja dalam dua kelompok kecil. Data dikumpulkan melalui lembar aktivitas yang berisi tugas membuat tiga program MATLAB dengan bantuan ChatGPT dan pertanyaan refleksi tentang pemahaman, tantangan, dan kepercayaan diri mereka. Hasil penelitian menunjukkan bahwa ChatGPT membantu mahasiswa memahami struktur program, mempercepat proses penulisan kode, dan meningkatkan rasa percaya diri dalam belajar pemrograman. Mahasiswa juga menyadari bahwa tidak semua jawaban dari ChatGPT langsung sesuai, sehingga perlu tetap berpikir kritis dan memeriksa kembali setiap kode. Secara umum, ChatGPT dinilai bermanfaat dalam proses belajar pemrograman, terutama jika digunakan bersama pemahaman konsep yang baik. Penelitian selanjutnya disarankan untuk melibatkan lebih banyak peserta dan menerapkan ChatGPT pada topik matematika lain.

Abstract

This study aims to determine the effect of the Realistic Mathematics Education (RME) model on students' learning outcomes. A quantitative approach with a quasi-experimental design was employed. The experimental group received instruction using the RME model, while the control group was taught using direct instruction. The population of this study consisted of all seventh-grade students at MTs Dakwah Islamiyah Putri Nurul Hakim in the 2024/2025 academic year, totaling 126 students divided into four classes. The sample was selected using simple random sampling, resulting in class VII B (32 students) as the experimental group and class VII C (32 students) as the control group. Data were collected using a learning outcome test. Hypothesis testing was conducted using the t-test, which yielded a t-value (tₕitung) of 3.203 and a t-table value (ttabel) of 1.999. Since tₕitung > ttabel, the null hypothesis was rejected, indicating a significant difference in learning outcomes between students taught with the RME model and those taught with direct instruction. The effect size was calculated to be 0.801, which falls into the moderate category. This suggests that the RME model has a meaningful impact on students' mathematics learning outcomes. outcomes of Grade VII students at MTs Dakwah Islamiyah Putri.
