High School Probability And Statistics Based On GeoGeBra Research On Instructional Design

Under the background of the increasingly developed educational information technology,the classroom teaching work carried out by teachers using modern information technology has been gradually widely used,and it also creates a superior objective environment for teachers to use modern information software to assist classroom teaching.The teaching content of probability and statistics in senior high school also puts forward further requirements on students' ability of information processing and statistical analysis.In order to achieve better teaching effects,many mathematics teachers have chosen to use modern information science software for auxiliary teaching.As a kind of dynamic mathematics application software,Geo Gebra has powerful data processing ability and drawing function,which can process a large amount of data and carry out dynamic fitting,thus improving classroom efficiency.At the same time,it can also cater to the law of students' cognitive development and thinking development,and improve students' mathematical core literacy such as data analysis and mathematical modeling.However,in real front-line teaching,teachers have low proficiency in relevant software and low frequency of use,resulting in poor classroom integration.Only by finding out key points to solve problems,can the role of Geo Gebra in assisting probability and statistics teaching in senior high schools be reflected.In this paper,probability and statistics course content as an example,compared with literature research methods,reading and sorting out the situation of the software assisted teaching at home and abroad,as well as the teaching status of probability and statistics,so as to form the research ideas;Further,guided by the theory of multiple representation and information education methods,the questionnaire was compiled from the perspectives of Geo Gebra's understanding degree and application frequency,learning attitude and views on the software,and the outline of educational interview was also written.Taking the mathematics teachers of the same level of key high schools in Harbin,Heilongjiang province as the main research object,the investigation and interview of teachers were carried out,and classroom observation was adopted to summarize the actual situation of teachers' application of software and students' feedback.On the basis of the above exploration process and combining the research status at home and abroad with the results of questionnaire survey and teacher interview,the author summarizes the principles for teachers to use Geo Gebra software to assist high school probability and statistics teaching design,namely the intuitive principle,the information block principle,the multiple connection principle and the systematic principle.And the teaching strategy,and further refinement of the process of preparing for the teaching strategy and teaching strategy to adopt,further,the author also selected the typical example,carries on the teaching design and classroom activity,combining theory with practice,finally came to the conclusion that the Geo Gebra software combined with high probability and statistics teaching design is feasible,The combination should follow certain principles and strategies and conform to the requirements of ?
