Pengaruh Media Wordwall Terhadap Hasil Belajar Ipas Materi Ekosistem Siswa Kelas v Sd Negeri 091273 Karang Bangun

This study examined the effect of Wordwall learning media on Grade V students’ learning outcomes in IPAS, focusing on ecosystems at SD Negeri 091273 Karang Bangun. The study used a pre-experimental method with a one-group pretest–posttest design. The participants were 24 Grade V students. Data were collected through learning-outcome tests administered before and after instruction using Wordwall, and analyzed descriptively, with a Shapiro–Wilk normality test, paired-samples t-test, and normalized gain analysis. The mean score increased from 37.29 on the pretest to 82.70 on the posttest. The reported paired-samples test yielded t = 14.201 with p < .001, indicating a statistically significant difference between scores before and after the intervention. The reported mean normalized gain was 0.7074, while the normalized-gain percentage was 70.74%, categorized in the source study as sufficiently effective; by commonly used numeric cutoffs, the mean gain value falls just above the high-gain threshold. These findings suggest that Wordwall may be a useful interactive alternative for teaching ecosystem concepts. However, because the study used a one-group design without a control group, the results should be interpreted as evidence of improvement after the intervention rather than definitive proof that Wordwall alone caused the improvement.
