<![CDATA[This study aims to investigate the effectiveness of the Predict-Observe-Explain (POE) learning model on the IPAS (Natural and Social Sciences) learning outcomes of Grade V students at SD Negeri 2 Sorong City. A quantitative pre-experimental approach was employed using a One-Group Pretest-Posttest Design, involving 25 Grade V students selected through a saturated sampling technique. Data were collected using a structured observation sheet and a 20-item performance test administered as both pretest and posttest. Instrument reliability was confirmed using Cronbach’s alpha, yielding coefficients of 0.603 (pretest) and 0.882 (posttest), both exceeding the minimum threshold of 0.60. The Shapiro-Wilk normality test confirmed that both pretest (sig. = 0.059 > 0.05) and posttest (sig. = 0.706 > 0.05) data were normally distributed. The paired-samples t-test yielded a calculated t-value of 12.850, which exceeds the critical t-value of 2.025 (df = 24, sig. = 0.001 < 0.05). The pretest mean score was 45.55, which increased to 80.00 following the POE intervention. These results confirm that the POE learning model has a statistically significant positive effect on IPAS learning outcomes, demonstrating its effectiveness as an innovative instructional approach for Grade V elementary school students.]]>
