Investigation And Research On The Construction Of Fractional Knowledge Group Of Sixth-grade Students

Fraction knowledge is an important content in elementary school mathematics learning.Modern education not only pays attention to the essence of knowledge,but also emphasizes the close connection between knowledge.Primary school students' learning psychological characteristics are mainly based on intuitive image memory.Therefore,building a complete knowledge group can help students better understand the learning content based on the connections between knowledge points.Based on this,the main questions of this research include:(1)How many knowledge groups can the elementary school score knowledge be divided into?(2)According to the SOLO classification and evaluation criteria,how about the construction of the score knowledge group of the sixth grade students? In order to provide teachers with better teaching scores and students better learning scores to provide useful suggestions.In order to solve the first problem,the researcher carefully read the relevant literature and combined the content of the score in the PEP textbook and the relationship between the knowledge of the score,and divided the elementary school scores into the representation of the score,the comparison of the size of the score,the basic nature of the score,and the meaning of the score.6 score-related knowledge groups including,score calculation and score conversion.In order to solve the second problem,the researcher prepared test papers based on the division of score knowledge groups,and conducted a test survey on sixth grade students in 2 urban schools and 2township schools.According to the SOLO classification theory,the grade knowledge group construction of sixth grade students is divided into levels.Through the SPPS statistical software,it analyzes the overall mastery of score knowledge by sixth graders,the construction of score knowledge groups for sixth grade students,and the differences in the construction of knowledge groups for sixth grade students in urban and rural areas.Combining the analysis of student survey data and the results of teacher interviews,it analyzes the reasons for the current situation of the construction of the sixth grade student score knowledge group,and gives corresponding countermeasures.This is also the innovation of this research.Through research,the conclusions are as follows:(1)Sixth grade students have a good overall construction of the score knowledge group,focusing on the M level and R level;(2)The construction level of the score representation knowledge group of sixth grade students is concentrated in the U level,M level and R level,and few students can reach the E level;The comparative knowledge group construction level of the score is concentrated in the U level,M level and E level;The significance of scores The level of knowledge group building is concentrated on M and R levels;the basic nature of scores is concentrated on R level and E level;The level of score calculation knowledge group is concentrated on M and R levels;The construction of score conversion knowledge group,the level is concentrated in the M level,R level and E level;(3)There is a significant difference in the construction of grade knowledge groups between urban and rural sixth grade students.The level of urban school students is significantly higher than that of rural school students.
