This research examines the PCK formation process on physical education with teachers who had less experience in primary schools. The study uses the qualitative research method with five teachers who have less with less than 5 years of (their) experience. Below is the conclusion of the study. When it comes to PCK about a curriculum, they formed each different PCK by their major from their university. In the cases of teaching practices, they rarely got any PCK experiences (of PCK) regarding physical education curriculum. They were able to study detailed PCK and organized it throughout the period of time they studied to attain take a teacher certification examination. In terms of PCK about curriculum and methods of teaching, they learned each different physical education curriculum and contents by their major or professors. They attained the detail of curriculum and teaching contents with their teaching practice experiences. They could get some PCK on the teaching contents and the way they teach generally and defined it through the course of the teacher certification examination. In the school they are working in, they improved their PCK with some advice from senior teachers, observing other teachers’ classes or attending teacher training programs about physical education. PCK on understanding what students are like is below. In their university time, the participants built a ‘big picture’ of their students the participants built a 'big picture' of understanding students. They were able to encounter (the) authentic classroom scenes, and they could develop their own PCK to make a better class. The period of studying for teaching certification examination helped (them) little to attain any understanding of their students. Understanding their students and finding their potential came rather through working in the school, where the were able to continuously meet student. Also experiences and advices from senior teachers provided them (to get) more knowledge on PCK in physical education.
