A Study On Comparing Two Sets With Strategies In 4-6-years Old Children

The purpose of this study is to understand the real level and diversity of middle-to-large class children in different grades of parks and urban and rural areas under different material conditions in the collection comparison.At the same time,it explores the strategies for children to use collective comparisons and the causes of errors when young children gather together.The reasons that affect the difference in the collection of young children.In this study,360 children from 6 kindergartens in Chengdu were surveyed and their parents were sent questionnaires.The conclusions are as follows:(1)The smaller the number of comparative collection elements presented by the title,the higher the adoption rate of young children;(2)The passing rate of young children in the closed arrangement is higher than the passing rate of the linear arrangement.The passing rate of the physical material is higher than the passing rate of the image;(3)Judging from the level of attainment achieved by young children,children in large classes,children in large classes in cities,and large-scale children in first-class gardens have reached a level of 8:9 regardless of whether they are closed or arranged in kind.The children in large classes in the secondary and secondary schools and the children in large-scale schools in the tertiary park have reached the 8:9 level in the closed arrangement,while the online arrangement has reached the 6:7 level;(4)Age,urban and rural areas,kindergarten level,closed and linear arrangement of materials,infant family background and children's learning environment are all important factors affecting the collection of children;(5)Children aged 4 to 6 tend to choose visual cues and counting strategies when they compare sets.Large class children are better able to use comparison strategies than medium class children,and most children use visual cues Are more prone to errors;(6)The reasons for the mistakes of 4-6-year-old children are all focused on visual judgment errors and mistakes,and the children in the larger class of middle-school children are more prone to problems such as missing numbers,repetitions,and hand-to-hand differences when they make points for large collections.
