The Reasons And Countermeasures For The Weak Data Analysis Ability Of High School Students

On the basis of Information and technology in today's society,the data has occupied a very important position.In today's basic education,data analysis ability is gaining extensive attention and the degree of recognition in cultivating the ability of data analysis for students is also gradually deepened.However,the data analysis ability of the current high school students is still weak,but a little search on the causes for the weakness of the high school students' data analysis ability.Therefore this paper focuses on the weak reasons and improvement measures of senior high school students' data analysis ability.The methods used in this paper are test volume survey,questionnaire survey and interview.Firstly,this paper analyzes the connotation of data analysis ability,and then uses the test volume method to investigate the current situation of data analysis ability of senior high school students.After that,according to the theory of ability formation and cultivation,combined with high school mathematics curriculum standard and student ability level to prepare questionnaires and test volumes,as well as the preparation of the teacher's interview outline,which used in taking investigation to students and face-to-face talking with teachers.On the basis of the statistical analysis performed,summed up the characteristics of students' learning and teachers teaching,and thus found that the reasons for giving rise to the weakness of the high school students' data analysis ability.Finally,according to the research results,the corresponding improvement measures and teaching cases are presented.In the level of investigation and study about the present situation of high school students' data analysis ability,we found that the data analysis capabilities are weak,especially the ability to interpret data and data reasoning.According to the results of student survey and test volume survey,we can find the reason of weak data analysis ability from the students' point of view: one is not fully understand and master the basic idea of statistics;The second is lacking of grasping data analysis methods, which can not be used what they had learn to solve practical problems;Third,the attitude of learning the statistical knowledge is not enough positive,and there has insufficient number of exercises;And four is can't seriously sum up and feedback on the lessons learned in class timely.According to the summary and analysis of teachers' interview results,the reasons for the weak data analysis ability of senior high school students from the perspective of teachers are as follows: firstly,at pr-class preparation,pay less attention to understanding of students' cognitive basis;Secondly,thinking on the examples,examples and exercises which chose are unreasonable and they had not been considered adequately in the aspect of consolidating the knowledge that combine with practice;Third,they explain the application of statistical knowledge is not comprehensive and thorough,and teach the methods of data analysis are too little;in the meantime,they are not pay attention to teaching statistical ideas in class;Fourth,the intensity of the job inspection is not enough and the inspection method is relatively simple;the effect of student learning Inspection and supervision of inadequate.In the end,according to the investigation result of the weak data analysis ability of senior high school students,the paper puts forward the corresponding teaching basic requirements.Including four basic requirements: strength the study of statistical methods,familiar with the application of statistical knowledge,strive to create an environment conducive to cultivating students 'ability to analyze data,improve the quality of statistical learning.And specific teaching requirements are made of preparation before class,classroom teaching and after-school feedback.Finally,a teaching case is presented for teaching requirements.
