Practice And Study On The Integration Of The Information Technology And The Junior Instruction Of Probability And Statistics

Since the notion of the integration of technology information and the subject teaching was first mentioned in "the course reform of the foundation education outline"in 2001,the integration has been developed rapidly up to now.And the achievement that the integration has bring to the basic education has been widely witnessed.Education has gradually entered the age of artificial intelligence.Since information technology entered mathematics education,not only the content of mathematical was changed,the classroom teaching mode and teaching evaluation mode has also been changed.Also,the traditional mathematics teaching has been innovated from all aspects.With the deepening of integration,the role of teachers has also changed correspondingly,from traditional knowledge imparting,gradually transformed into a student learning instructor.However,with the achievements of informative teaching coming out rapidly and continuously,it is a great challenge for front-line teachers to find out how all kinds of high-tech software and hardware can take root in the regular classroom."Statistics and probability" is a science that studies the statistics law of random phenomenon in quantity,it has unique thinking mode that different from studying deterministic phenomenon in elementary mathematics,this thinking mode mainly manifested as randomness,generality,radiation,direction and creativity of thinking.Therefore,this knowledge is difficult both in teaching and learning,many students also reflect that the knowledge of statistical and probability is difficult to understand and master;some teachers also have deep feelings in teaching.""Practice after learning"model is not conducive for students to form a statistical and mathematical thinking habit,using "experimental" teaching model,then in practice there are many restrictions,such as limited time in the classroom,lack of laboratory conditions,students' improper operation in the experiments,these restrictions are also not beneficial for students to improve problem-solving ability.Therefore,finding a way which can not only give you enough space to operate but also ensure adequate problem-solving training is the key to solve the probability problems in teaching in junior middle school.The advantage of information technology has bring to the classroom is self-evident,but how to choose the ones that are suitable for actual need from the various kinds of technologies,and make it useful in the service of classroom teaching and learning,how to choose the reasonable mode of integration,to make the students play a principle role in the class,and obtain the maximum understanding of knowledge with active attitude,is the realistic problem faced by us,when dealing with the teaching of probability and statistics in junior high school.This paper is based on the existing information technology and mathematics curriculum integration research result and the front-line research condition,mainly to solve the following problems:1.Searching for new method of teaching junior middle school probability and statistics by means of Excel,Geometer's Sketchpad and learning platform online;2.Summarizing the principles and methods of integrating information technology into the teaching of probability and statistics junior middle school;3.Putting forward the opinion of adapting the textbook "probability preliminary" in the twenty-fifth chapter of grade nine of PEP.
