This paper combines theories with practice, explores and discusses the general principles of swimming instruction, applies techniques of skill transfer and proposes way to apply to actual teaching situations. Furthermore, according to the theories of technical transference, and adapting the experimental methods (comparing and programming covered in three groups), this paper verifies the transferring status and relationship of three types of swimming skills: a.) simulative ability practice; b.) underwater swimming; c.) breathing - at different teaching phases technique-ambination. Thus I draw a conclusion that all the techniques and skills are somehow interrelated and directly affects students studying and grasping of these swimming techniques and skills. This paper is also significant for us to promote and accelerate the teaching process and will accomplish the mission of teaching swimming more successfully.
