This article outlines a junior high school physical education class which teaches basketball in English using the CLIL framework as a case study. The purpose of the article is to consider how and what students learned from the class through students’ class results, basketball skills test, post lesson questionnaire and pre and post lesson teacher interviews. It examines how the teacher’s attitude toward CLIL changes from pre and post lesson interviews. Through this CLIL class led not by English teachers but by a physical education teacher the qualities and abilities necessary for competent CLIL teaching are considered. Regarding students, this CLIL lesson was conducted for the acquisition of physical basketball skills, English expressions and situational English ability. It also aimed to teach 21st-century skills defined by global education. The lesson resulted in students being able to understand both the English target structures and the basketball terms and strategies taught. In addition, students not only learned the content of the lesson, but also co-operated well with the teacher and worked well in teams which made the lesson successful. Before the lesson, the teacher felt that the CLIL lesson would be difficult for the students. However, the lesson was well received and had a great effect on the students and the teacher herself gained confidence. The experience they gained will lead to skills that will help them succeed in a global society in the future.
