Abstract

This study aims to determine the effect of the Realistic Mathematics Approach on students’ spatial abilities in the topic of plane figures in the fourth grade at SD Negeri 101770 Tembung during the 2025/2026 school year. This study employed a quasi-experimental method using a Nonequivalent Control Group Design. The study subjects consisted of 41 students, including 23 students in the experimental class and 18 students in the control class. The research instrument was a multiple-choice spatial ability test that met the criteria for validity, reliability, difficulty level, and discriminative power. Data analysis was conducted using Normalized Gain (N-Gain) scores, which were subsequently tested for normality, homogeneity, and analyzed using an Independent Samples t-test with the assistance of SPSS version 26. The results showed that the average N-Gain for the experimental class was 0.7877, which falls into the high category, while the average N-Gain for the control class was 0.5333, which falls into the moderate category. The results of the hypothesis test showed a significance value (Sig., 2-tailed) of 0.000 (< 0.05), indicating a significant difference in the improvement of spatial ability between the two classes. These findings suggest that the Realistic Mathematics Education approach is more effective than the Teacher-Centered Learning approach in improving students’ spatial ability. This effectiveness is supported by the characteristics of the Realistic Mathematics Education approach, which utilizes real-world contexts, exploratory activities, discussions, and the process of knowledge construction, enabling students to build visual representations, understand relationships between shapes, and develop their visualization, relational, and spatial orientation skills in a more meaningful way when studying plane figures.

Abstract

ABSTRACT This study aimed to determine the effect of the Teams Games Tournament (TGT) learning model using Science Ludo media on the cognitive learning outcomes of fifth-grade students in ecosystem material at MIS H.M. Hefni during the 2025/2026 academic year. This study employed a quantitative approach with a quasi-experimental method using a Nonequivalent Control Group Design. The sample consisted of 60 students selected through total sampling, including 30 students in the experimental class and 30 students in the control class. Data were collected through multiple-choice pre-tests and post-tests, as well as observation sheets. Data analysis included normality and homogeneity tests followed by the Independent Samples t-test using SPSS. The results showed that the experimental class achieved higher learning outcomes than the control class. The hypothesis test produced a significance value (Sig. 2-tailed) of 0.039 (p < 0.05), indicating that H₀ was rejected and H₁ was accepted. Classroom observations also indicated high levels of student enthusiasm and participation during the learning process. Therefore, the Teams Games Tournament (TGT) learning model using Science Ludo media had a positive and statistically significant effect on students' learning outcomes in ecosystem material. Keywords: Ecosystem, Learning Outcomes, Science Ludo, Teams Games Tournament (TGT). ABSTRAK Penelitian ini bertujuan untuk mengetahui dan menganalisis pengaruh penerapan Model Teams Games Tournament (TGT) berbantuan media Ludo Sains terhadap hasil belajar kognitif peserta didik kelas V pada materi ekosistem di MIS H.M. Hefni Tahun Ajaran 2025/2026. Penelitian ini menggunakan pendekatan kuantitatif dengan metode quasi experiment melalui desain Nonequivalent Control Group Design. Sampel penelitian berjumlah 60 peserta didik yang ditentukan menggunakan teknik total sampling, terdiri atas 30 peserta didik kelas V Al-Malik sebagai kelas eksperimen dan 30 peserta didik kelas V Al-Hafiz sebagai kelas kontrol. Data dikumpulkan melalui tes pilihan ganda pada pre-test dan post-test serta lembar observasi. Analisis data meliputi uji normalitas, uji homogenitas, dan uji hipotesis menggunakan Independent Samples t-test dengan bantuan SPSS. Hasil penelitian menunjukkan bahwa peningkatan hasil belajar pada kelas eksperimen lebih tinggi dibandingkan kelas kontrol. Uji hipotesis memperoleh nilai signifikansi (Sig. 2-tailed) sebesar 0,039 (p < 0,05), sehingga H₀ ditolak dan H₁ diterima. Hasil observasi juga menunjukkan bahwa peserta didik antusias dan berpartisipasi aktif selama pembelajaran. Dengan demikian, penerapan Model Teams Games Tournament (TGT) berbantuan media Ludo Sains berpengaruh positif dan signifikan terhadap hasil belajar peserta didik pada materi ekosistem. Kata Kunci: Teams Games Tournament (TGT), Ludo Sains, hasil belajar, ekosistem.

Abstract

This study aimed to examine the effect of implementing the reward and punishment method on the numeracy skills of third-grade students at UPT SPF SDN 104205 Tembung in the 2025/2026 academic year. The study employed a quantitative approach using a pre-experimental method with a one-group pretest-posttest design. The sample consisted of 21 third-grade students. The research instrument was a numeracy skills test that had met the validity and reliability requirements. Data were analyzed using the normality test and the paired-samples t-test. The findings showed that the mean pretest score increased from 59.43 to 78.86 in the posttest, representing an improvement of 19.43 points. The normality test indicated that the data were normally distributed, while the hypothesis test produced a t-value of 13.535 with a significance value of 0.001 (< 0.05), indicating that the null hypothesis was rejected. These findings demonstrate that the implementation of the reward and punishment method has a significant effect on students' numeracy skills. The method not only improves numeracy achievement but also enhances students' motivation, participation, and discipline during the learning process. Therefore, the reward and punishment method can be considered an effective instructional strategy for improving elementary school students' numeracy skills.
