<![CDATA[This study was motivated by the low learning outcomes in Natural and Social Sciences (IPAS) among fourth-grade students at SD Negeri 173307 Sipultak, which were presumed to be influenced by teacher-centered instruction and the limited use of varied learning models and interactive instructional media. This study aimed to determine students' learning outcomes before the implementation of the collaborative learning model assisted by Kahoot, to examine its effect on IPAS learning outcomes, and to measure the magnitude of its influence. This research employed a quantitative approach using a One Group Pretest-Posttest Design. The research sample consisted of 30 fourth-grade students. Data were collected through tests, questionnaires, and documentation studies. The research instruments were tested for validity and reliability, while data analysis was conducted using the normality test, correlation coefficient test, coefficient of determination, and hypothesis testing (t-test). The findings revealed that the mean pretest score of 52.66 increased to 77.97 in the posttest, while the average questionnaire score reached 84.63, indicating that students' responses were categorized as very good. The results of the normality test indicated that the data were normally distributed, thereby meeting the assumptions for parametric statistical analysis. Furthermore, the correlation analysis showed a positive relationship between the implementation of the collaborative learning model assisted by Kahoot and students' learning outcomes. The hypothesis test also confirmed that the collaborative learning model assisted by Kahoot had a statistically significant effect on the IPAS learning outcomes of fourth-grade students at SD Negeri 173307 Sipultak in the 2025/2026 academic year. Therefore, the collaborative learning model assisted by Kahoot is effective in improving elementary school students' IPAS learning outcomes. ABSTRAK Penelitian ini dilatarbelakangi oleh rendahnya hasil belajar IPAS siswa kelas IV SD Negeri 173307 Sipultak yang diduga dipengaruhi oleh pembelajaran yang masih berpusat pada guru dan belum memanfaatkan model pembelajaran yang bervariasi serta media pembelajaran interaktif. Penelitian ini bertujuan untuk mengetahui hasil belajar siswa sebelum penerapan model pembelajaran kolaboratif berbantuan media Kahoot, mengetahui pengaruh penerapannya terhadap hasil belajar IPAS, serta mengetahui besarnya pengaruh yang diberikan. Penelitian ini menggunakan metode kuantitatif dengan desain One Group Pretest-Posttest Design. Sampel penelitian berjumlah 30 siswa kelas IV. Teknik pengumpulan data meliputi tes, angket, dan studi dokumentasi. Instrumen penelitian telah memenuhi uji validitas dan reliabilitas, sedangkan analisis data dilakukan melalui uji normalitas, uji koefisien korelasi, koefisien determinasi, dan uji hipotesis (t). Hasil penelitian menunjukkan bahwa rata-rata nilai pretest sebesar 52,66 meningkat menjadi 77,97 pada posttest, sedangkan rata-rata skor angket mencapai 84,63 yang menunjukkan respons siswa berada pada kategori sangat baik. Hasil uji normalitas menunjukkan data berdistribusi normal, sehingga memenuhi syarat untuk analisis parametrik. Selanjutnya, hasil uji korelasi menunjukkan adanya hubungan positif antara penerapan model pembelajaran kolaboratif berbantuan media Kahoot dengan hasil belajar siswa, sedangkan uji hipotesis membuktikan bahwa terdapat pengaruh yang signifikan terhadap hasil belajar IPAS siswa kelas IV SD Negeri 173307 Sipultak Tahun Ajaran 2025/2026. Dengan demikian, model pembelajaran kolaboratif berbantuan media Kahoot! efektif digunakan untuk meningkatkan hasil belajar IPAS siswa sekolah dasar. ]]>
