A Survey And Research On The Status Quo Of Data Analysis Concepts Among Junior High School Students

"Mathematics Curriculum Standards for Compulsory Education"(2011 edition)proposes that data analysis is the core of statistics,but the question types of statistics and probability are relatively simple and fixed.Analytical concepts are not well developed.The purpose of this research is to investigate the level of data analysis concept of junior high school students,and to put forward relevant suggestions based on the survey results,to strengthen teachers' attention to this aspect,and to cultivate students' data analysis concept.This research first collects relevant core concepts,and conducts a literature review on"the connotation of data analysis concepts","the division of data analysis concept levels" and"the status quo of junior high school students' data analysis concept levels".Year Edition)",as well as Tong Li et al.'s classification criteria for the connotation of data analysis concepts,combined with real questions,simulated questions in the senior high school entrance examination,and topics in journals,excellent master's thesis,to compile a specific,comprehensive set of student data that can be tested.Analyze the test papers of the concept level and test the students.After collecting the test papers,according to the division basis of the data analysis concept level,assign the corresponding score to the students,so as to analyze the students' data analysis concept level in each dimension,and analyze the correlation between the students' data analysis concept level and mathematics academic performance.gender,and differences in the level of mathematical analysis perceptions among students of different genders.Through the students' answers,the cognitive difficulties of the students in the data analysis process are diagnosed,and targeted suggestions are put forward.By investigating and analyzing the data analysis concept level of junior high school students,this study draws the following conclusions: The data analysis concept level of junior high school students is generally low,and the applicability is poor;there is no significant difference between junior high school students' data analysis concept level and students' gender;There is a significant positive correlation between junior high school students' data analysis concept level and students' mathematics academic performance.Based on the conclusions of the investigation and research,this study puts forward specific suggestions for teaching in the field of statistics and probability,hoping to provide some teaching suggestions for mathematics teachers.
