Abstract

The purpose of this study was to determine whether there was an effect of stretching after aerobic activity on the resting heart rate of SMA 1 Jeneponto futsal players. The research subjects in this study were futsal athletes, totaling 10 male athletes. This research is an experimental research. The instrument used to measure and obtain responses from abilities, performance, behavior of samples or objects in data collection for stretching tests after aerobic activity on pulse from Sulistiyono (2017). The data collection technique uses tests and measurements. . Data analysis techniques using SPSS using descriptive analysis, normality test, T test. Based on the results of the data and discussion from this study it can be concluded that there is an effect of stretching after aerobic activity on the resting pulse of futsal players. From the data of the active stretching group, the pre-test value obtained an average pulse rate of 107.5. the post-test value obtained an average pulse value of 92.2. P value of 0.001 (p <0.05) thus there is an effect of active stretching on the decrease in pulse rate of SMA 1 futsal players Jeneponto

Abstract

This study develops and evaluates the Environment-Based Mathematics Learning (EBML) model as a transformational instructional approach to improve learning quality and outcomes in secondary mathematics. The model integrates environmental exploration, contextual problem-solving, and collaborative inquiry to strengthen students’ conceptual understanding. Using a developmental research design, EBML was validated through expert assessments, classroom observations, student responses, and pre–post learning performance. The validation results show a high level of conceptual and structural validity (average score 3.72), while practicality tests indicate strong acceptance among teachers (90.63%) and students (92.16%). Effectiveness analysis demonstrates significant improvement in learning outcomes, with achievement increasing from 62.06% to 87.79% and a gain index of 0.68. Student activity also remained consistently high across all learning stages. The findings confirm that EBML is a feasible, effective, and contextually rich model that transforms mathematics learning by connecting abstract concepts to meaningful environmental experiences.
