Abstract

This study aimed to examine the effect of explosion box media integrated into a discovery learning model on the chemistry learning outcomes of Grade XI students at SMA Negeri 14 Gowa in the 2024/2025 academic year, specifically on the topic of reaction rates. The study employed a posttest-only control group design. The population consisted of three Grade XI chemistry classes, from which samples were selected using random sampling. The selected classes were XI.C1 (34 students) as the experimental group and XI.B1 (36 students) as the control group. The independent variable was the use of explosion box media, while the dependent variable was students’ learning outcomes. Data were collected through a learning achievement test and analyzed using both descriptive and inferential statistical techniques. The results of descriptive analysis showed that the mean score of the experimental group (84.12) was higher than that of the control group (76.25). The prerequisite test indicated that the data were homogeneous but not normally distributed; therefore, hypothesis testing was conducted using the Mann–Whitney U test. The results revealed that Z_calculated > Z_table, leading to the acceptance of H₁ and rejection of H₀. In conclusion, the use of explosion box media within the discovery learning model has a significant effect on improving students’ chemistry learning outcomes on the topic of reaction rates.
