This research is a pilot study aimed at analyzing the intensity of male and female students' learning movement comparison using a polar global positioning system (GPS). It is a comparative study, and participants in this study were junior high school students aged 12-13 years, totaling eight students (four males and four females). The research instruments used were Polar GPS RC3 and Polar Heart Rate Sensor H3 to measure the distance and heart rate of students during the learning process. All participants were given a tactical learning model and a technical learning model on different physical education learning days. After that, they were analyzed comparatively to find out the difference. The results showed differences in the intensity of movement in male and female students, with the tactical learning group had higher intensity of movement. Besides, the average male students had higher movement intensity than female students. This study's findings could be used as evaluation material for teachers to improve the physical education teaching and learning process quality. Furthermore, the use of technology, such as the Polar Global Positioning System (GPS), helps teachers monitor their students' level of physical activity. Since this research is a pilot study, further research is needed to determine the differences between the two learning models and gender-based student movement intensity more comprehensively. Besides, the comparison of giving feedback during the lesson is also suggested for further research.

The purpose of this research was to produce an exercise model in the form of simulation of narae chagi development technique for beginner tekwondoins in Special Region of Yogyakarta. The technique simulation was adapted to the characteristic aspects of upper elementary school age students through physical activities focusing on multilateral movements packed in a manual book and VCD (Video Compact Disk). The approach taken in this research was research and development. ConclusionThe product development of narae chagi technique simulation model for beginner taekwondoins was done in eight stages, namely: (1) collecting research result and information, (2) analyzing the product to be developed, (3) developing the initial product, (4) doing expert validation , (5) conducting small-scale and revisedtrials,(6)conductinglarge-scaletrialsandrevisions,(7)makingfinalproducts,and(8) testing effectiveness. The results of this study in the form of narae chagi kick exercises on novice taekwondoins which contains five games, namely: (1) preparation model, (a) initial attitude, (b) basic motion, (2) implementation model, (a) kick, (b) landing, (3) simulations model.
