The Effect of Using the WordWall App on Students’ Academic Achievement in 4th-Grade Science at Public Elementary School No. 72 in Bengkulu City

This study aims to analyze the effect of using the Wordwall application as an interactive learning medium on the learning achievement of fourth-grade students in Natural and Social Sciences (IPAS) at SD Negeri 72, Bengkulu City. The study employed a quasi-experimental design with a pretest-posttest control group model involving 52 students divided into an experimental group and a control group. Data were analyzed using the Mann–Whitney U Test and N-Gain analysis. The results showed a statistically significant difference in learning outcomes between the two groups (p < .05). The experimental group achieved a higher average posttest score (82.69) than the control group (71.54). Furthermore, the N-Gain score was 0.56 for the experimental group, indicating moderate improvement, compared with 0.30 for the control group, indicating low improvement. These findings suggest that using Wordwall as an interactive learning medium has a positive effect on students' learning achievement and can support more engaging and effective IPAS learning.
