Abstract: The purpose of this study is to find out how effective the teaching of badminton practice is at improving the ability of students majoring in sports at Jakarta State University (UNJ). Twenty students majoring in sports (15 men; 5 women) attended the teaching of badminton practice for 16 meetings with the same teaching method and length of practice. The portion of practical training for men and women is not distinguished. The effectiveness of teaching badminton practice is assessed from the results of the final test for service, lob, chop, smash, netting, and footwork compared to the initial test for all techniques. Significant improvement was obtained only in the practice of chop and netting techniques although other techniques also improved. With this, it can be concluded that teaching badminton practice at Jakarta State University is able to improve the badminton abilities of students majoring in sports, especially for chop and netting techniques.
