Selection Of Evaluation Indexes For Motor Learning Ability Of 7-8-Year-Old Children In Xi’an

Research purpose:This research is one of the subprojects of the National Social Science Foundation Project "Research on the evaluation index and development norm of action learning ability of school-age children(7-15 years old)"(17xty007).The purpose of this study is to test the reliability and validity of the measurement and evaluation indexes of7-8-year-old children’s motor learning ability,that is to optimize the measurement and evaluation indexes of 7-8-year-old children’s motor learning ability,so as to provide data support and methodological support for the development of the measurement scale of Chinese children’s motor learning ability.Research methods:Through literature research and expert interviews,the concept of motor ability,motor development sequence,motor measurement and evaluation indicators at home and abroad were collected and sorted out,and the primary selection of test indicators was completed through the expert questionnaire.The primary indexes were measured and tested for validity,reliability,discrimination and difficulty,so as to determine six test indexes suitable for the evaluation of 7-8-year-old children’s action learning ability.Results:1.In the factor load matrix after orthogonal rotation,there are four common factors for the characteristic root greater than 1.Through factor analysis,the physical fitness test indexes are: standing long jump(0.827),softball long throw(0.728),upright arm holding forward bend(0.713);the mental energy test indexes are: balance beam walking back and forth(0.536),10 meter grid jump(0.517),6-step run long jump(0.707).2.In the difficulty test,standing long jump(100%),standing arm forward bend(100%),softball throw(100%),balance beam walk(95%),10 meter grid jump(88%),6-step run-up long jump(85%).3.The reliability test results of the selected indexes showed that the correlation degree of the two tests was high: standing long jump(0.943),standing arm forward bend(0.977),softball long throw(0.924),balance beam walking back and forth(0.876),10 meter grid jump(0.965),6-step running long jump(0.968).The results of index objectivity test showed that the scores of each index were highly correlated(the correlation coefficients were 0.926,0.896,0.864,0.893,0.913,0.956,respectively).The results show that the indicators selected in this study meet the requirements of reliability and objectivity of monitoring indicators.4.In this study,six indexes of motor learning ability were selected for person correlation analysis.The results showed that the correlation between the indexes was moderate or low.It shows that no one test index can replace other indexes.At the same time,it shows that any single item test index can not completely replace other indexes as the test index of the action learning ability of the subjects.5.7-8-year-old male and female school-age children’s movement learning ability indicators,male and female students in standing long jump,standing arm forward bend,softball throw far indicators of the difference is large and significant(P < 0.01),boys in standing long jump,softball throw far items are significantly better than girls(P< 0.01),girls in standing arm forward bend items are significantly better than boys(P< 0.01).There was no significant difference between male and female in the indexes of 10 meter grid jump,balance beam walk and 6-step run-up long jump.6.In the 7-year-old age group,boys had better scores in standing long jump and softball throw than girls,and there was a big difference between boys and girls.Boys’ standing long jump and softball throw were significantly higher than girls(P<0.01).The results of female students were significantly higher than that of male students(P<0.05).There was no significant difference between boys and girls in 10 meter grid jump,balance beam walk and 6-step run-up long jump.7.In the 8-year-old age group,there was a significant difference between male and female students in the vertical arm holding forward bending and softball throw,among which the female students’ vertical arm holding forward bending was significantly higher than that of male students(P<0.01),and the male students’ performance in softball throw was significantly higher than that of female students(P< 0.01).There were no significant differences between boys and girls in the items of10 meter grid jump,6-step run-up long jump,standing long jump and balance beam round-trip walk.Conclusion:(1)The theoretical research on the selection of motor learning ability is weak.At home and abroad,there are few researches on the motor learning ability,lack of theoretical research.The theoretical research on motor learning mainly focuses on the study of motor skill learning,through various methods to improve the students’ motor ability,the related structure of motor learning ability.At present,the research on the evaluation of motor learning ability is in a blank situation in China.(2)In this study,41 test indexes were selected by experts and practical tests,and6 indexes were finally selected,including standing long jump,10 meter grid jump,standing posture holding arm forward bend.The indexes of mental energy are: long throw of softball,round-trip walk of balance beam,6-step run-up and long jump.(3)The six selected test indexes of motor learning ability are reliable,effective,safe and feasible in theory and operation,with high reliability and validity.It can meet the measurement requirements and the characteristics of 7-8-year-old school-age children.
