The Development Status And Teaching Strategies Of Junior Middle School Students' Data Analysis Ability

Mathematical problems cannot be separated from analysis and production from generation to solution.For junior high school students,understanding the mathematical ideas of randomness and using data ability is the foundation to further adapt to the development of society and individual,Knowledge and skills,rational and dialectical analysis and solution to real problems.Therefore,the cultivation of students' data analysis ability occupies a very important position in the mathematics course of basic education.Statistics,as one of the most important contents in basic mathematics education,has the ultimate goal of developing students' understanding of statistical ideas and application of statistical methods to improve their data analysis capabilities.In 2011,the "Compulsory Education Mathematics Curriculum Standard" promulgated the original concept of "statistical analysis" in "Mathematical Curriculum Standard for Full-time Compulsory Education(experimental draft)" as "data analysis concept." As one of the ten core concepts of mathematics education in the compulsory education phase,what is the level of data analysis ability of junior high school students at the present stage has become a topic of great concern.Based on the junior middle school mathematics teachers' teaching strategies to improve students' ability to data analysis as the research object,using questionnaires,classroom observation,interviews and other research methods,understand the problem of data analysis ability in junior high school students at present stage,further analysis on students data analysis ability of the junior middle school stage teaching Suggestions about the ability of data analysis.The questionnaire test found that the data analysis concept of junior middle school students was lower overall.The data analysis of junior middle school students is good,but the process ability is low.Junior high school students have a lack of systematic cognition of randomness and statistics.In view of the above problems,through further classroom observation and interview,the author analyzes the shortcomings of teachers in the teaching of data analysis content: focusing on teacher explanation,ignoring students' exploration and experience;Emphasis on calculation and scoring,ignoring the cultivation of thinking ability.In view of the above problems,the following four teaching Suggestions are proposed for the training of data analysis ability of middle school students at the present stage:1.Create teaching situation to help develop the data analysis ability of junior middle school students.2.To strengthen the data analysis ability of middle school students in the whole process of application data statistics.3.Close to life,design teaching,guide students to understand the random phenomenon deeply.4.Through teaching reflection,teachers realize the accumulation and innovation of data analysis teaching skills.
