Abstract

This research aims to determine the effect of the Jarimatics method on calculation speed and student learning outcomes in class IV multiplication material at Muhammadiyah Elementary School. This research is the experimental research. The population in this study were all fourth grade students at Muhammadiyah elementary school. The sample in this study was all class IV, totaling 11 students. The sampling technique in this research was a saturated sampling technique. Saturated sampling technique is a sampling technique where all members of the population are sampled. Based on the research results and discussion analysis, the data in this study is normally distributed and homogeneous with a significance level for data normality of 0.868 > 0.05, and a significance level for data homogeneity of 0.143 > 0.05. Hypothesis testing in this research uses the paired sample test (t-test). Based on the results of the hypothesis test, the significance value for calculating speed was obtained at 0.000 < 0.05 and the significance value for learning outcomes was 0.00 < 0.05. So it can be concluded in this study that Ho is rejected and Ha is accepted, meaning that the Jarimatics method influences the speed of calculation and student learning outcomes in class IV multiplication material at Muhammadiyah elementary school.

Abstract

This study aims to examine the effect of jump rope on leg muscle strength in physical education classes for sixth-grade elementary school students. Traditional games are movement-based activities designed to support students' physical development through active participation. A quantitative approach with a quasi-experimental nonequivalent control group design was used in this study. Participants were sixth-grade students divided into an experimental group (n = 23) and a control group (n = 24). The experimental group received physical education through the traditional jump-rope game, while the control group received conventional instruction. Before the analysis, normality and homogeneity tests were conducted to determine the appropriate statistical procedure. Leg muscle strength was measured using a vertical jump test administered at the pretest and posttest. Data analysis focused on group differences using the Mann–Whitney test on change scores (posttest–pretest). The Mann–Whitney test results showed a U value of 176,000, Z = -2.279, and a p-value of 0.023 (< 0.05), confirming a significant difference between the experimental and control groups. These findings indicate that the traditional jump-rope game is effective at increasing leg muscle strength. This study was limited to leg muscle strength; further research could explore the broader impact on other motor skills and across different educational contexts.
