| Serve is one of the most important skills in the tennis, which is also the unique hitting method without interfering by the opponents. It is also the difficult part in tennis teaching. In order to further understand and research its and main causes and solution scheme; In this paper, taking the multimedia techniques as research object, combining the ways to make the tennis teaching perfect and taking the traditional sports education pattern as contrast to help the students to grasp this skill faster. Furthermore, taking the professional students form Jiujing College as experiment object which were used to carry out a verification test based on the modern information technique which could offer the references to the tennis education.Taking forty professional students form Jiujing College as experiment object and divide them into two groups (experiment group and contrast group) according to their age, height, weight and level of serving (n=20). The action indexes were checked according to the differences between two groups after training lating 16 weeks. All the experiment objects were recorded by the video so that further analyze its action of throwing the ball, pose of back scratcher, bending the arm with wrist turn and knee bend, wielding the racket, success rate and serving speed in tennis teaching.The results show that:(1) The parameters of throwing action of research object, including horizontal distance of hitting, throwing height, height of hitting are all improved significantly, but the top point of hitting is reduced, the parameters of experiment group is better than contrast group after the sixteen weeks training based on different teaching way.(2) Each parameter of research objects at the end of back scratcher, including elbow angle, bend angle of knee joint and hip joint are all improved significantly, meanwhile, the variation degree of experiment group is higher after the sixteen weeks training based on different teaching way.(3) The minimum right knee angle of parameter of action of crouched-genuflex and pedal and stretch during the tine of racked swing , including bend angle degree of left knee, bend angle degree of right knee, pedal and stretch degree of left knee and pedal and stretch degree of right knee are all improved significantly, the variation degree of experiment group is higher after the sixteen weeks training based on different teaching way.(4) The minimum right knee angle of parameter of action of crouched-genuflex and pedal and stretch during the tine of racked swing , including bend angle degree of left knee, bend angle degree of right knee, pedal and stretch degree of left knee and pedal and stretch degree of right knee are all improved significantly, the variation degree of experiment group is higher after the sixteen weeks training based on different teaching way.(5) The parameter of action of racked swing, including right elbow, left hip, right hip, left knee and its angle are all reduced significantly, the reducing degree of experiment group is higher after the sixteen weeks training based on different teaching way.(6) It is obvious that the parameters of serving is more get close to the top tennis player, especially, the speed of grasp this skill, the teaching achievement is significant after the sixteen weeks training based on different teaching way.Conclusions:(1) The throwing action, each action of back scratcher, action of crouched-genuflex and pedal and stretch during the tine of racked swing and action of racked swing is changed a lot which is more get close to the top tennis player, it's obvious that the experiment group is much better than contrast group.(2) The traditional teaching pattern has itself-advantages, which was represented at the end of test but there were still lots of disadvantages as well. The traditional teaching pattern was largely affected by old teaching concept and teaching thought of "kairov" which emphasized the teacher location in teaching process and regarded the students as the passive position always understand that the student position in teaching process should subordinate to the teaching pattern of the teachers. In such a old teaching pattern, the students should act the teacher and do what the teacher ordered to them. This old teaching pattern also used to play an important role in the sports talent training at the initial period of new china, for instance, improving civil quality. However, the old teaching pattern could also restrict the creative ability of the students which is harmful to technique learning of students.(3) The combination between modern information technology and traditional teaching pattern could shorten the learning time to grasp the serve technique.(4) The combination between modern information technology and traditional teaching pattern could make a harmonious teaching atmosphere which could arouse interests of students and improve teaching effect.(5) The effect of modern information technology on teaching achievement is significant, which supply a new teaching innovation concept for us and make the tennis teaching diversified so that it could improve the tennis teaching quality. |
