基于联系数的乒乓球教学不确定性感受研究

A Study on Uncertain Feelings of Ping-Pong Teaching Based on the Connection Numbers

在乒乓球教学中学生的不确定性感受是影响到乒乓球教学效果的一个重要因素 ,应用集对分析联系数可以把不确定性感受与确定性感受作为一个系统加以分析 ;通过对 3 4 0名学生的问卷调查 ,了解到男生的确定性感受平均值是 0 72 + 0 0 7j,是不确定性感受值 0 2 1的 3 1倍 ;女生的确定性感受平均值是 0 53 + 0 10j,仅是不确定性感受值 0 3 7的 1 2倍 ;但男女生各自的平均感受联系度态势都属于强同势 。

The students uncertain feelings during Ping-P ong learning process is one of the major factors on the effectiveness of Ping-P ong teaching. The uncertain feelings can be analyzed systematically with the app lication of pair analysis based on the Connection number. The authors have disco vered that the average value of certain feelings for boy students is 0.72+0.07 through questionnaire investigation for 340 students,which means that the value of uncertain feelings is 0.21 out of 3.1 times. While the average value of the c ertain feelings for girl students is 0.53+0.10j,which indicates that there is on ly 0.37 uncertain feelings out of 1.2 times. However,the authors also have found that the average feelings for boy and girl students in a degree connection situ ation are closely related to same power. Freqent practice and training are one o f the main methods for reducing the uncertain feelings.
