Intuitive Teaching Practice Research In "Statistics And Probability" Of Junior High School Based On Super Sketchpad

With the development of economic level,the significance of "Statistics and Probability" knowledge has been continuously reflected.In July 2001,the "Full-time Compulsory Education Mathematics Curriculum Standard(experimental draft)" was promulgated in China,which officially incorporated the content of the "Statistics and Probability" module into the compulsory education stage.After ten years of practice,the "Full-time Compulsory Education Mathematics Curriculum Standard"(hereinafter referred to as the 2011 edition “Curriculum Standard”)was promulgated in China in 2011,executed in the autumn of 2012.The 2011 edition “Curriculum Standard” adjusts some parts of the knowledge in "Statistics and Probability" module in the primary school stage into junior high school stage,which increases the teaching task difficulty of "Statistics and Probability" module of mathematics in junior high school stage.Moreover,the 2011 edition “Curriculum Standard” puts forward the higher requirements for learning the "Statistics and Probability" module in the curriculum objective.Based on this,how to improve the teaching quality and carry through guiding ideology of the new curriculum standard has always been an urgent problem for the teachers.The intuitive teaching method has always been one of the important mathematics teaching methods,which was developed by leaps and bounds with the wide use of information technology in education.As a compulsory course for middle school mathematics curriculum,the "mathematics in information age" represented by computer technology forces us to integrate information technology with mathematics classroom teaching and stimulate the modern mathematics teaching by informatization,to give full play to the advantages of information technology and improve the teaching performance.Based on the new curriculum reform concept of the mathematics in junior high school,under the guidance of modern educational thought and learning theory,the research aims to use the information technology of Super Sketchpad to carry out the investigation and research in questionnaire investigation,interview,lecture,experiment,and other methods by taking the "Statistics and Probability" teaching in junior high school as an example.Step one,analyze the classroom teaching situation of "Statistics and Probability" in junior high school through interviews and questionnaires;step two,investigate and survey theapplication situation of Super Sketchpad in "Statistics and Probability" teaching in junior high school through the questionnaire and lectures;Step three,analyze and discuss the effect of Super Sketchpad for "Statistics and Probability" teaching in junior high school through the experimental study;finally,according to the results of investigation and experiment,analyze the relationship between Super Sketchpad and intuitive teaching of "Statistics and Probability" in junior high school,and put forward the specific strategies of Super Sketchpad in the application of "Statistics and Probability" teaching,so as to strengthen the "Statistics and Probability" intuitive teaching by the better use of the Super Sketchpad.
