中学生全面运动技能发展的要素结构与教学聚类手段模型评价

Essentials Structure of Development of Middle School Students'Overall Movement Skills and Evaluation of Clustered Teaching Means Model

运用实验法和模糊数学聚类分析等方法,对中学生运动技能的教学手段进行定量分析和建立模糊综合评价教学模型。从25种常用教学手段模糊聚类的因子结果发现,速度力量素质因子U_1、身体控制能力因子U_2和翻转协调能力因子U_3对综合运动技能发展的贡献率较高。在此基础上,根据相关因素与教学手段的模糊相关统计和教学手段的模糊聚类分析,提出了发展中学生全面运动技能的评价内容、方法和标准。初步证明了以3类因子变量数据U_1、U_2、U_3为主要内容的、发展学生全面运动技能教学指标的有效性。

The methods of experiment, blur-math clustered analysis etc. were applied to making a quantitative analysis of the means of teaching to middle school students and setting up a model for the vague and comprehensive evaluation of teaching. The factor result of 25 common-used teaching means being vaguely clustered shows that the three factors of speed and power quality （U1）, balance and control ability of body （U2） and turning harmonization ability （U3） have a higher contributive rate to the development of the students＇ synthetic movement skills. On this basis and according to the vaguely correlative statistics of related factors and teaching means and vaguely clustered analysisof teaching means, it put forward the contents, methods and criterion of evaluating the development of middle-school students＇ overall movement skills and initially proved the effectiveness of teaching indexes of developing the students＇ overall movement skills, which took the three sorts of factor variable data U1, U2 and U3 as main contents.
