The concept of teaching in physical education has evolved from a teacher-centered approach to a more student-centered approach to develop problem-solving skills and critical thinking in games. This study aims to provide insight and better understand the TGfU pedagogical process of in-game teaching. The method used is a quasi-experimental mixed-methods with a pre-test and post-test design and involves 43 students consisting of (21 girls and 22 boys). The results of the study based on the average difference test on female students showed that the decision-making variable value t = 28,06, technical execution 17,01, game performance 29,06, enjoyment 17,87 significantly α = 0,05 is 1,721. Male students, the value of decision-making 18,56, technical execution 13,54, game performance 13,53, and enjoyment 16,15 significantly α = 0,05 is 1,782. All variables give students the ability to solve learning problems. Students can think to make decisions, be actively involved in the game, have opportunities to learn basketball game techniques well, and participate in game patterns when attacking or defending in the TGfU unit. TGfU also provides enjoyment for students in the physical education learning process in basketball games. The advantage of using the TGfU approach can provide ideas for teachers to make game designs so that students are effectively involved in this unit, and students' abilities and skills in learning the game of basketball can be achieved.
