Orthogonal Experimental Research On Facade Smashing Technique Of P.E. Education Volleyball Major

Smashing technological action is one of fundamental technology projects of volleyball, is the most effective attacking weapon and the main way of getting score in competition. Above all, directly smashing technique is the basis of various smashing technique, which is the derivation of strong attack, quick attack, back row attack, close net button, distant net button, button adjustment ball and various offensive tactics, and is one fundamental technology that every special field volleyball major student should master. However, by surveying find that, most students of special field volleyball major of colleges and universities sports feel difficult to control facade smashing technique, concrete showing on the opportunity of run up to jump is not well, the midair batting is not exact, smash the ball wielding arm action is rigid , and the rate is slow and so on. Looking for the reason, which is not only related to the students'physical constitution and teaching time, but is also more relevant to the choice of tuition method and the rational combination of the training methods. Therefore, how to make use of limited teaching time and to choose rationally the training means in order to obtain the yard adapting to volleyball facade smash teaching efficiency and mass, which is already becoming the current problem demanding prompt solution of every sports college.On the basis looking up, collecting large amount of document data's and by the questionnaire, five exercise methods have been sifted out from several facade smashes exercise methods. Applying the method which orthogonal experiment and verify experiment to be tied in wedlock each other, we do the research for giving preferential treatment of facade smash technology of teaching to sport special field of volleyball students. The mission of studying is included mainly: (1)Design a questionnaire, to choose and ascertain the factor carrying out an experiments and their level; (2) Design and put orthogonal experiment into practice , strict supervisory control on process of the experiment; (3)Carry out statistics treatment on the data that the experiment reaches, ascertain the factors'primary and secondary order; (4) Select the optimization grouping which affects the facade smash technology'all factors; (5)Adopt double the collation teaching experiment to check the experiment bear fruit.Applying the orthogonal experiment'result indicate: Five experiment factors'primary and secondary order of the technology affecting the volleyball major student'facade smashing is: Interpose an approach run taking off line mark (A) , language hint (B), buckle fixed ball exercise(C), the entire smash of Number Four place practice (D) , action carries out presentation on the smashing (E). The optimum factor level is all horizontal 2, which is to say the effect of having these training methods to train better than not having these ones. However, by that the method difference analysis factor E can be excluded because of its unmarked index effect. Therefore, the final effective training method of improving a volleyball major student'facade smash technology is C2D2A2B2。Adopt synchronism teaching and contrast verify experiment to indicate, the combination teaching training method of fa?ade smashing is more effective than routine teaching of means to improve student facade smash engineering level and achievement, and to decrease student mentality anxiety during the period of learning smashing technique directly , forming fairly good internally piloting and space perception. Two wheels of experiments bear fruit show clearly, giving preferential treatment and combination of teaching and training method to the volleyball students'facade smashing technique is rational, what be selected combination teaching training methods to improve the volleyball facade smash technique is effective.
