The Effect of the Discovery Learning Model on the Learning Outcomes of Fifth Grade Students in Integrated Science and Social Studies at SDN 06 Kampung Lapai

The learning outcomes of fifth-grade IPAS students at SDN 06 Kampung Lapai compared with conventional learning. This study employed a quantitative approach using a quasi-experimental method with a Nonequivalent Control Group Design. The population consisted of 60 fifth-grade students divided into an experimental group and a control group, with 30 students in each group. Data were collected through learning outcome tests administered as pretests and posttests and were analyzed using prerequisite tests and an Independent Samples t-test. The results showed that the experimental group's mean pretest score was 45.83, increasing to 61.83 in the posttest, while the control group's mean pretest score was 39.83, increasing to 48.33 in the posttest. Thus, the experimental group showed an average increase of 16.00 points, compared with 8.50 points in the control group. Hypothesis testing indicated that the use of the Discovery Learning model had a significant effect on the learning outcomes of fifth-grade IPAS students compared with conventional learning. Therefore, Discovery Learning can be used as an alternative instructional model to improve IPAS learning outcomes among elementary school students.
