Research On Evaluation Index Of Primary Mathematics Classroom Teaching Based On Data Analysis

Under the background of the information education era,the traditional subjective,human and experiential classroom teaching evaluation has been unable to objectively and scientifically expose the problems in classroom teaching.A lot of valuable and meaningful data in the classroom is often overlooked.And it is these neglected data that allow us to observe the behavior of teachers and students in the classroom more rationally and accurately,and then pay attention to their development.Therefore,the author used the "Big Data Observation Platform of View Structure Teaching in Dawan Primary School" to study the evaluation indexes of primary school mathematics classroom teaching based on data analysis.Combination of academic background and work reality,research data to the classroom observation for protection,through technical analysis,data discussion,construct the four levels of elementary school mathematics classroom teaching effectiveness evaluation,teaching design,teachers' answering questions and students,students to participate in the situation,group work,to change the teacher's teaching behavior and students' learning behavior,form the science,harmony and beauty education.This paper mainly consists of four parts.Firstly is about the introduction.As the basic part of this study,the introduction introduces the origin of the problem,the purpose and significance of the research,the research ideas and methods,and defines the relevant concepts.This paper reviews the educational research,change,evaluation and classroom teaching evaluation period,methods and classroom teaching evaluation indicators under the context of big data,so as to reflect on the reference and shortcomings.Secondly,the first chapter is the conceptual transformation of primary school mathematics classroom teaching evaluation under the background of big data application.Based on the analysis of the traditional concepts and limits of the classroom teaching evaluation of primary school mathematics,this paper puts forward the challenges and application of the concepts to the classroom teaching evaluation of primary school mathematics in the context of the application of big data.Combined with data analysis,the theoretical dimensions of teaching design,teacher and student behavior,group activity of primary school mathematics classroom teaching evaluation are improved.Thirdly,the second chapter is the evaluation index determination of primary school mathematics classroom teaching based on data analysis.Questionnaire is used to investigate the real situation of teachers' behavior and students' behavior in primary school mathematics classroom,which provides the basis for determining the evaluation index of primary school mathematics classroom teaching.Standardize the four levels of data collection,for the primary school mathematics classroom teaching evaluation index really make adequate preparation.The evaluation index of primary school mathematics classroom teaching is constructed by using the data obtained from the implementation of the "big data observation platform of teaching viewpoint structure in Da-Wan primary school".In terms of the effectiveness of instructional design,there is the time distribution of each link.In teacher question and student answer aspect,there are the number and level of the teacher's questions,the number and level of teacher evaluation,the number of students who answer together,the number and level of students who answer alone,the number and level of student teacher activities.In student participation aspect,there are scope of student participation,response level,regional distribution.In terms of group work,there are percentage of completion and time spent.Lastly,The third chapter is the application of evaluation index of primary school mathematics classroom teaching based on data analysis.Through data analysis in the classroom,teachers,students three aspects of the application of indicators for the micro presentation.The overall presentation of index application is carried out through the four lessons of data analysis.This paper expounds the application effect of the evaluation index of primary school mathematics classroom teaching based on data analysis,optimizing the teaching behavior of teachers,optimizing the learning behavior of students,optimizing the evaluation of classroom teaching,promoting the professional development of teachers,improving the quality of students,and promoting the autonomy,efficiency and harmony of classroom teaching.This paper puts forward the future development direction,such as continuously collecting data,paying attention to the continuity and correlation between data,and doing a good demonstration and guidance based on mathematics.
