By the methods of experimentation and mathematical statistics,a research was made on the (acquisition) of volleyball techniques for 14~16 year old girls in order to probing into combinations of four different teaching methods (Type A_Ⅰ: analysis-synthesis;Type A_Ⅱ: analysis-analysis-synthesis;Type B_Ⅰ: synthesis-analysis-synthesis;Type B_Ⅱ: synthesis-synthesis) and their impacts on student's learning. The result showed that type B_Ⅱ was mainly used during the volleyball teaching. Type AI and Type A_Ⅱ could help the students with the mastery of the basic technologies of football and volleyball,but the teaching effect was not as obvious as in cultivating the actual combat ability and tactics consciousness. Though B_Ⅱ availed to cultivating the actual combat ability and tactics consciousness,the teaching effect was not as obvious as type B_Ⅰ?type A_Ⅰ and type A_Ⅱ for the students to master the basic technologies.
