Abstract

This study aimed to develop the “Treasure Hunt Obstacle” game in Physical Education, Sports, and Health (PJOK) learning to improve elementary school students’ gross motor skills. This study employed a Research and Development (R&D) method using the ADDIE development model consisting of analyze, design, develop, implement, and evaluate stages. The research subjects consisted of elementary school students involved in small-scale and large-scale trials. Data collection techniques included observation, media expert validation questionnaires, learning expert validation questionnaires, and student response questionnaires. Before implementation, the student response instrument was tested for validity and reliability. The validity test results indicated that all instrument items were declared valid in both small-scale and large-scale trials, while the reliability test obtained a Cronbach Alpha value of 0.88, categorized as highly reliable. The media expert validation achieved a percentage of 90%, categorized as feasible, while learning experts obtained an average percentage of 92.50%, also categorized as feasible. Student responses in the small-scale trial reached 92.6%, while the large-scale trial reached 84.1%, with an average score of 88.35%, categorized as very good. The implementation results showed that the “Treasure Hunt Obstacle” game was able to increase students’ activeness, enthusiasm, and gross motor skills in PJOK learning. Therefore, the developed game is feasible to be used as a PJOK learning model in elementary schools. Keywords: ADDIE, Elementary School, Game, Gross Motor Skills, Physical Education

Abstract

Dollyo chagi is one of the most commonly used techniques in taekwondo competitions that require physical ability, specifically speed. This study aims to determine the impact and effectiveness of modified strength training using rubber resistance bands on improving the speed of the dollyo chagi kick among taekwondo athletes at the RTA Academy Dojang in Kendal Regency. This study employed an experimental method using a one-group pretest-posttest design. The study sample consisted of 20 athletes aged 12–17 years, selected using purposive sampling. The research instrument used a 10-second dollyo chagi kicking speed test, measured in the number of kicks. The intervention was administered over 16 sessions, with a frequency of four times per week. Data analysis involved tests of normality, homogeneity, and hypothesis testing using a paired-sample t-test via the SPSS programme. The results of the study indicate that the data are normally distributed and homogeneous. The mean pretest score of 16.50 increased to 20.50 in the posttest. The results of the paired sample t-test showed a calculated t-value of -24.658 with a significance level of 0.000 (p < 0.05), indicating a significant difference between the pre-test and post-test results. It can therefore be concluded that training using modified rubber tyre resistance bands has a significant and effective impact on improving the speed of the dollyo chagi kick in taekwondo athletes.
