With　the　introduction　of　artificial　intelligence　technology,　the　traditional　teaching　methods　are　no　longer　used　in　physical　education.　The　traditional　means　are　not　competitive　and　can　not　mobilize　the　enthusiasm　of　students.　However,　the　new　computer-aided　teaching　has　not　been　recognized　by　most　physical　education　teachers.　There　are　still　great　problems　in　this　aspect.　Computer　aided　instruction　(CAI)　has　developed　into　intelligent　computer　aided　instruction　(ICAI).　ICAI　not　only　overcomes　the　weakness　of　traditional　CAI,　but　also　greatly　improves　the　effect　and　efficiency　of　physical　education.　In　this　paper,　the　characteristics　and　functions　of　CAI　system　are　analyzed,　and　a　corresponding　implementation　framework　is　given.　©　Published　under　licence　by　IOP　Publishing　Ltd.
