Abstract

This research aims to analyze the effect of the Numbered Heads Together (NHT) cooperative learning model on the learning outcomes of basic passing techniques in volleyball among grade X students of SMA Negeri 1 Mendoyo. This study uses a quantitative approach with a quasi-experimental method and a non-randomized control group pretest-posttest design. The research sample consists of two classes, namely the experimental class and the control class, each comprising 33 students selected randomly. The experimental class receives treatment with the NHT learning model, while the control class follows the conventional learning model. The data collection instrument is conducted through practical tests of basic underhand and overhand passing techniques in volleyball. The data were analyzed using normality tests, homogeneity, t-tests, and effectiveness calculations. The research results showed a significant improvement in student learning outcomes in the experimental group compared to the control class. The average lower passing score in the experimental group was 81.12 and the upper passing score was 81.33, which is much higher compared to the control class that obtained average scores of 44.97 and 39.76, respectively. The significance value of the t-test is 0.000 (p < 0.05), indicating that the NHT learning model has a significant impact on improving learning outcomes.

Abstract

This study aims to determine the effect of swimming activities on the development of balance and motor coordination in early childhood at SDK Marsudirini, Jembrana Regency. The research method used was quasi-experiment with *non-equivalent control group* design. The sample consisted of 42 early childhood students, which were divided into experimental groups (n = 21) and control groups (n = 21). The research instruments were balance and motor coordination tests conducted at pre-test and post-test. The data were analyzed using quantitative descriptive methods. The results of the paired t-test showed significant improvement in the experimental group in both aspects of balance (pre-test: 12.3 ± 1.8; post-test: 17.8 ± 2.0; p = 0.000) and motor coordination (pre-test: 14.5 ± 2.1; post-test: 19.6 ± 2.4; p = 0.000). In contrast, the control group showed no significant changes in either aspect. The independent t-test also showed significant differences between the experimental and control groups in the post-test results of balance (p = 0.000) and coordination (p = 0.000). These findings confirm that swimming activities can significantly improve balance and motor coordination in early childhood, so it can be used as one of the recommended educational approaches in children's physical education programs.
