An Investigation And Research On The Current Situation Of Students' Concept Of Data Analysis

The intersection of data and information technology continues today,data has become inseparable from the lives of contemporary people.The Full-time Compulsory Education Mathematics Curriculum Standard(2011 Edition)(hereinafter referred to as the 2011 Curriculum Standard)also puts forward corresponding requirements,that is,emphasizing the“data analysis concept” as one of the ten core keywords in the curriculum design.This means that with the course of the curriculum reform,the “data analysis concept”,compared with the“statistical concept” proposed in the 2001 experimental curriculum standard,can better reflect the needs of basic education development and also reflect its response to the call of the times.Since then,under the call of cultivating “data analysis concept” and improving students' data analysis ability,researchers have paid attention to “data analysis concept”,and are racing to carry out a series of research related to data analysis concept.After reading the literature,this study found that foreign research results on data analysis concepts are mainly concentrated in the data analysis concept evaluation framework,and its impact is also greater;domestic research focuses on the connotation of data analysis concepts and research,investigation and research are relatively fewer,and the conclusions are mixed.Therefore,based on the interpretation of the data analysis concept in the 2011 version of the curriculum standard,the author defines the concept,draws on and modified Professor Tong Li and others to establish a related theoretical evaluation framework,compiles student test papers according to the framework,and evaluates the second learning through the student test papers.The current development of students' data analysis concepts,and then through teacher survey questionnaires and interview results analysis,to explore possible factors that affect the development of students' data analysis concepts,and then put forward targeted and effective suggestions on this basis,with the hope of analyzing teachers' data The teaching provides a certain reference and reference.This research mainly considers the following questions: What is the status quo of students' data analysis concepts in the second semester? What are the possible influencing factors? What suggestions should be made?Through the analysis of the test results,the thesis understands the status quo of students' data analysis concepts,and concludes that there are both good aspects of the current situation of students,but also existing deficiencies or potential problems.Among them,the good status quo is:(1)The ability to perceive data random phenomena is relatively good;(2)The development level of male and female data analysis concepts is generally more balanced;(3)The higher the grade,the higher the student's data analysis concept development level it is good.Potential problems include:(1)Low awareness of data and data analysis;(2)Inadequate understanding of the information contained in data;(3)Difficulties in the selection and application of data analysis methods.Based on the current situation and potential problems,through teacher questionnaire survey and interview results analysis,this study believes that the possible factors that affect the development of students' data analysis concepts are:(1)teachers do not pay enough attention to data analysis concepts and have deviations in understanding;(2)teachers conduct overall planning The ability of data analysis activities is low;(3)the students' attention to data analysis is not high;(4)the students seldom experience the whole process of data analysis.Based on the analysis of the survey results and comprehensively considering the results of teacher interviews,the following training suggestions are put forward for the development of the second-semester student data analysis concept:(1)Strengthen concepts and attach importance to teaching;(2)Carry out practice with internal and external assistance(3)Create a situation and select materials reasonably;(4)Pay attention to the process and guide participation.
