The Current Situation And Improvement Measures Of High School Students' Data Analysis Literacy

In the deepening of the curriculum reform of basic education in the process of the development of students mathematical literacy has become the core focus and difficulty of the current high school education.As one of the core data analysis mathematical literacy development of high school students,become the core of high school probability and statistics teaching.However,the present data analysis on how the literacy of high school students,not only is the high school mathematics teachers the general confusion problems,and even the theory worker and dazed.Clarify the data analysis of the development of literacy of senior high school students is the practical problems of mathematics education urgently in high school.Based on the data analysis of literacy survey of senior high school students as the subject,by questionnaire survey method,interview method,literature research method,with 196 senior high school students,44 high school mathematics teachers as the research object,through a comprehensive and objective investigation of Henan province compulsory 3 "statistics and probability" of the teachers' teaching and students' the current situation,and then sort out the high school mathematics literacy status data analysis,put forward on the basis of further improvement measures.The survey results showed that:1.On the one hand,is visited by the high school students,the data analysis of the low overall level of literacy of high school students,only to 30.6%.On the other hand,ignoring the data analysis of literacy,high school probability and statistics teaching focus on training knowledge and skills training on repeat,is the main reason for the data analysis of low literacy senior high school students.2.High school low quality data analysis,from the cause of the students,on the one hand,is that a large number of students has not been really clear statistics and probability method of study,it is equal to how to determine the mathematics learning algebra a few;On the other hand,the overall level of the students' practical application ability is bad,especially to statistics and probability associated with the boundless universe,stay on the set of patterns to solve stage study.3.High school students' low quality of data analysis,from the reasons for teachers,concentrated in:(1)Teachers will focus on the teaching of probability and statistics on the exam oriented education,neglect of probability and Statistics Teaching in the early convergence of high school students' knowledge of knowledge,resulting in fault,discusses some important concepts of fuzzy understanding,affect learning;(2)The teacher's teaching idea is old,it is only limited to the teaching method of teaching,most of them adopt a large number of repeated training,ignoring the problem solving method,which brings heavy burden to the students' study;(3)In daily teaching,teachers ignore the cultivation of mathematical thinking methods,especially the idea of mathematical modeling;(4)Teachers' inadequate preparation,neither research curriculum,does not understand students situation,formulate the teaching goal is too empty,is not in conformity with the actual situation of students;(5)The teacher's own statistics and probability knowledge reserve is insufficient,at the same time,teachers do not pay attention to the students' statistical and probabilistic knowledge in time,it is difficult for students to establish their own knowledge structure;(6)The level of application of information technology is low,and it is very strange to the teaching software and multimedia equipment.In order to improve the teaching of statistics and probability of senior high school students,and then improve the overall level of data analysis literacy of high school students:First,to further clarify the characteristics of probability and Statistics Teaching(especially to determine the difference in mathematics teaching characteristics),help students experience the process of data analysis,the information contained in the data of attention;Secondly,multimedia,geometric drawing software,the actual use of technology in statistics and probability in the teaching of the teacher training schools,suggestions accordingly,for the high school teachers must effectively enhance the probability and statistics teaching software,the application level of hardware;Third,to strengthen the knowledge of probability and statistics and other related knowledge,so as to establish the perfect knowledge structure.Finally,pay attention to timely infiltration of historical data of Mathematics statistics and probability field,and further strengthen the case teaching provide practical application case,probability and statistics for the more high school math teacher.
