Preliminary Visual Instructional Design Research On The Probability Of Junior High School

Preliminary teaching and learning on Probability has always been one of the focus of mathematics education at home and abroad,which formally entered the stage of compulsory education in our country in 2001.Relatively,the preliminary education research on probability is lagging behind in domestic.In order to further implement the concept of curriculum standards,this paper does the exploration and research on the preliminary teaching and learning on Probability.According to the "mathematics curriculum standard"(2011edition)in compulsory education,what the "probability of preliminary teaching in junior high school" require is: Being able to make lists,draw tree diagrams and so on can work out all possible outcomes in random events,as well as in specified events,which can know about the probability of the event;Knowing that frequency can be used to estimate probability through a large number of repeated experiments." It is clear that visualization methods such as charts and graphs are the key to elementary probability teaching and learning in junior high school.About the preliminary probability teaching material design and teaching practice in junior high school,there are still some worthy improvements in the visualization method of implementing the requirements of course standards.,such as making lists,drawing tree diagrams with no standard visualization design.In order to better implement the visualized teaching method,firstly this paper use the literature method,comparison method,the content analysis method,comb visual theory foundation and teaching requirements,and build the initial visual teaching design,process and model on junior high school probability.This paper also stands from the angle of the probability knowledge,visualization tools,cognitive habits and so on,analyse the mathematical visualization knowledge which is easy for students to receive,understand,apply,spread and innovate,and constantly revise visualization tools with the feedback,in order to achieve a more reasonable and scientific visualization of mathematics teaching.Secondly,the preliminary probability visualization teaching design,process and model of junior middle school is used to analyze and compare the preliminary probability teaching requirements of mathematics curriculum standards,mathematics textbooks and examinationquestions in mathematics.Third,based on the construction of probability design process model of the initial visual teaching in junior high school,use the dynamic and static visual tools,such as EXCEL information technology,the geometric sketchpad software,Wayne figure,mind mapping,and line segment,to have visualization teaching design on preliminary probability content in junior middle school nine-hour mathematics teaching material of Peoples Education Edition,which is to intuitively help students understand the concept of probability,grasp the classical probability formula and principle,acquire probability thinking method and seek the simple solving method on probability problem.It is worth noting that this paper only analyzes the teaching assumption of mathematics knowledge visualization in the preliminary probability of junior middle school,and does not carry out teaching practice test on the preliminary probability visualization teaching design of junior middle school,which is exactly the direction of further research in the future.
