Abstract


Abstract:  This study aims to analyze the effect of using modern learning media in the form of mathematics e-modules on the short-term memory abilities of fifth-grade elementary school students. This study uses a quantitative approach with a quasi-experimental design of the one-group pretest–posttest type. The research subjects consisted of 12 students selected through purposive sampling based on variations in short-term memory abilities. Data collection was conducted through pretest and posttest, each consisting of 15 questions to measure changes in students' short-term memory abilities before and after the implementation of the mathematics e-module. The data were analyzed using prerequisite tests, paired samples t-test hypothesis tests, and N-Gain analysis. The results of the study indicate that the implementation of e-modules in mathematics has a positive impact on improving students' short-term memory abilities, as shown by N-gain scores ranging from 0.50 to 0.91 with an average value of 0.67 (moderate category) and N-gain percentages ranging from 49.93% to 90.87% with an average of 67.14%. In addition, the results of the paired samples t-test showed a significance value of 0.000 (< 0.05), indicating a significant difference between the pretest and posttest scores. Thus, it can be concluded that the mathematics e-module is effective in improving students' short-term memory abilities and has the potential to become an alternative modern learning medium that supports more meaningful mathematics learning and is in line with the demands of education in the digital era.


Abstrak: Penelitian ini bertujuan untuk menganalisis pengaruh penggunaan media pembelajaran modern berupa e-modul matematika terhadap kemampuan memori jangka pendek siswa kelas V sekolah dasar. Penelitian ini menggunakan pendekatan kuantitatif dengan desain kuasi-eksperimen tipe one-group pretest–posttest. Subjek penelitian terdiri atas 12 siswa yang dipilih melalui teknik purposive sampling berdasarkan variasi kemampuan memori jangka pendek. Pengumpulan data dilakukan melalui tes awal (pretest) dan tes akhir (posttest), masing-masing terdiri atas 15 butir soal yang digunakan untuk mengukur perubahan kemampuan memori jangka pendek siswa sebelum dan sesudah penerapan e-modul matematika. Data dianalisis menggunakan uji prasyarat, uji hipotesis paired samples t-test, serta analisis N-Gain. Hasil penelitian menunjukkan bahwa penerapan e-modul matematika memberikan dampak positif terhadap peningkatan kemampuan memori jangka pendek siswa, yang ditunjukkan oleh nilai N-Gain berkisar antara 0,50 hingga 0,91 dengan nilai rata-rata sebesar 0,67 (kategori sedang), serta persentase N-Gain antara 49,93% hingga 90,87% dengan rata-rata sebesar 67,14%. Selain itu, hasil uji paired samples t-test menunjukkan nilai signifikansi sebesar 0,000 (< 0,05), yang mengindikasikan adanya perbedaan yang signifikan antara skor pretest dan posttest. Dengan demikian, dapat disimpulkan bahwa e-modul matematika efektif dalam meningkatkan kemampuan memori jangka pendek siswa dan berpotensi menjadi alternatif media pembelajaran modern yang mendukung pembelajaran matematika yang lebih bermakna serta selaras dengan tuntutan pendidikan di era digital.
