Investigation And Research On Data Analysis Ability Of High School Students

In the information age,data is a kind of wealth,and data analysis is an important way to obtain wealth.In the latest senior high school math curriculum standard,the 2017 edition,it is clearly pointed out that data analysis is one of the core qualities that must be cultivated by high school students,which highlights the importance of data analysis as a new mathematical language to express the real world in the information age.In order to clarify the current learning situation of high school students' statistical knowledge and the level of data processing ability,this study compiled questionnaires and test papers on the basis of a review of existing research at home and abroad.After the test,combined with the test results,the questionnaire and the test paper were revised,and then the formal test was carried out.After analyzing the data,the main conclusions are as follows:1 · High school students' ability to analyze data is weak.2.Both gender and department have no statistically significant relationship with the data processing ability of high school students.3.Both grade and school have statistically significant relationship with high school students' data processing ability,and the effects are mild.4.The four abilities of high school students' data analysis ability include strong ability to extract information,data collection,data collection,and analysis and inference.5.The ability of high school students to collect data is weak,the ability to collate data is good,the ability of extracting information is excellent,and the analysis and inference ability of high school students is very weak.6.The high school students' views on statistical knowledge are positive,but their positive attitude can not be transformed into positive behavior.7.High school students have a moderate assessment of their own statistical knowledge,and a higher degree of recognition for the teaching of teachers' statistical knowledge.8.Some knowledge related exercises in high school mathematics statistics have little effect on improving the ability of data analysis.Finally,the corresponding suggestions are given from three aspects of school,teachers and students,which mainly including:appropriate burden reduction for students and more intercollegiate exchanges;focusing on concept teaching,focusing on linking up with statistical knowledge of junior high school,and focusing on the connection between knowledge,actual life,focusing on the quality rather than the quantity of exercises,and attaching importance to the position of statistical knowledge in mathematics in middle schools,in order to let students experience the whole process of data analysis;actively participate in practical activities,do not let their interest be buried,and often sum up learning methods.Don't brush the subject blindly.
