EDM Based Analysis Of The High School Mathematical Examination Results In Lhasa

After the math test,it is an indispensable link for teachers to evaluate and explain the test papers to students,an important process in the overall math teaching,and an important means for teachers and students to check and fill gaps.It is an important method for teachers to check teaching quality,students to deepen understanding,answer doubts and expand thinking.However,there are still many problems in teachers' evaluation of examination papers.First of all,when preparing for lessons and commenting on the examination papers,the analysis and exploration of the examination papers themselves are mainly through the statistics and ranking of the total scores of the examination papers to calculate the average score,which is then displayed with intuitive names,scores and ranking information.Teachers and students can intuitively see the students' scores,which has a certain incentive effect on students.However,teachers do not attach much importance to the analysis of the specific examination contents of the examination papers and the reasons for students' dropping points.Although the traditional analysis of test paper scores can give students an overall grasp of the learning situation,it is difficult to find out the specific rules of students' mastery of knowledge points and the root causes of the loss of test paper scores if the information shown by test paper scores such as total score and average score is analyzed.Secondly,after investigation,it is found that most teachers have not been guided by scientific methods for the teaching mode of evaluating and speaking test papers.Such as "one size fits all for the whole class","teachers teach students to listen" and "mechanical teaching" are still the main teaching modes for teachers to evaluate and speak mathematics examination papers.However,the above traditional "spoon-feeding" teaching mode is not a scientific method.They ignore the subjectivity and difference of students,ignore that students are people with independent consciousness,and violate the student-centered teaching concept.Therefore,the above teaching mode is not advocated by the new curriculum reform in our country,and it is this teaching mode that makes the evaluation of mathematics examination papers fail to achieve the desired teaching effect.Then,in today's times of frequent examinations,it is of utmost importance to excavate more value of test paper data,optimize the evaluation of test papers,and promote the improvement of students' scores.In addition,with the more and more extensive application of modern information technology in education and teaching,Chinese mathematics teaching and research personnel have also begun to test new methods to improve the evaluation of mathematics examination papers,but there are still many problems that need further study and solution.In view of this,this paper deeply analyzes the teaching situation and the fundamental problems of senior high school mathematics examination paper evaluation through literature,questionnaire and other methods.The research object is the students of two high schools in Lhasa,which rank above the middle and below the middle.Its purpose is to investigate and analyze the current situation of mathematics examination paper evaluation and students' ideas in different levels of schools in Lhasa,to discover the problems existing in examination paper evaluation,and to further use advanced data analysis methods to analyze examination papers and prepare lessons for examination paper evaluation.That is,through WEKA platform,the association analysis and cluster analysis in Educational Data Mining technology(hereinafter referred to as EDM)are applied to the analysis of examination papers to better prepare the evaluation of examination papers,and the analysis results are applied to the evaluation of examination papers.Through examples,suggestions for evaluation of examination papers based on EDM are put forward,and their feasibility and advantages are verified.The innovation and value of this paper are two points: first,provide a new method of examination paper analysis to front-line teachers through examples,break the current situation that traditional examination paper analysis ignores the analysis of examination paper knowledge points,and prepare lessons more scientifically to comment on examination papers;Second,the education data mining and the examination paper evaluation are linked together,and teaching suggestions are put forward to front-line mathematics teachers according to the information behind the examination paper obtained by the education data mining,so that the examination paper evaluation is more scientific,and the traditional examination paper evaluation teaching mode is broken,thus improving the examination paper evaluation efficiency.
