Open Motor Skills Evaluation Criteria

The purpose of this study:Over the years, we have in sports skills teaching habits purely technical architecture point ofview from the sport commence teaching, this approach is more appropriate for the closureskills, but due to the neglect of skills to the formation of interaction with the environment willaffect the open movement learning skills. Open motor skills due to their own characteristics,the decision to learning the principles of complexity and breadth of learning field, in additionto the basic movement learning, but also requires a combination of a grasp on theenvironment anticipation, the choice of technology to the development of thinking, judgment,and many other capabilities, these capabilities are also strongly advocated in the new sportscurriculum and teaching reform, such as inquiry ability, innovation ability.In this study, starting from the open motor skill learning principles and the influencing factorsof the various stages in the teaching of motor skills, learning to analyze, and ultimately anopen motor skill evaluation criteria. And the open tennis sport, for example, open motor skilllearning principle, under the guidance of forehand skills evaluation criteria and the teachingcontent of the organizational arrangements, and ultimately through the analysis on theteaching of experimental results achieved on the open movement skills evaluation standardsand learning principles of empirical research.The research method of this paper: the literature material law, the expert interview law,questionnaire, teaching experiment, video observation, mathematical statistics, logic analysismethod.The main conclusions are:1, tennis forehand stroke skill evaluation criteria:(1) to predict theball direction: the correct sentence beforehand to the direction of the ball, according to theopposing batting action aloft, to predict the ball direction addresses (mobile, backswing).(2)to predict the ball placement: can correctly predict placement, according to the player of theother side, the ball hitting the height and route, predict the ball to the ball to predict placementof mobile, timely.(3) Anticipation: batting position after moving in place before the judgebounce height and position, the bounce of the ball to the best hitting point body side frontwaist height.(4) Mobile timing: the player hit the ball, the ball over the net when not moving.(5) Pace is moved to the position degree: can arrive at the batting position, the center ofgravity of the body stand, is stable against the ball.(6) The overall rhythm: a backswing tobatting, a momentary pause; batting to follow through coherent and smooth.(7) The centre ofgravity of the whole stability: from backswing to end of stroke weight remained stablewithout ups and downs.(8) A backswing end position: in sideways, arm microbendingconditions, head back to court the maximum extended position.(9) A backswing opportunity:on the other side hit the ball after ball over the net, has not started a backswing.(10) Battingswing rhythm: rapid acceleration, coherent without stasis action.(11) a best position: the pivotfoot forward, waist height.(12) The ball’s direction: to plan the direction of ball athletes.(13) Repetition: enter the athlete program in the landing area.In2, combined with the open motor skill and the characteristics of this experiment tennisforehand stroke skill evaluation standard, to open motor skill evaluation standards are asfollows:(1) To the sports technology required in the movement of tecnical standards(2) Anticipation to analyze" environment", according to the opponent’s actions, habits,"advance" responds.(3) Technical effect on match or coaches required technical effect.
