The Research On Probability Model In Senior High School And Teaching Advice

Along with the content of probability walking into senior high school mathematics course,there are more and more reseaches of the content and teaching methods of probability in mathematics education field,as well as taking out primary effect.Yet it is not long before probability becomes a part of senior high school mathematics course.Many teachers can,t comprehend thoroughly,just rest on the superficial understanding of the knowledge about probability.And plenty of problems emerges in teaching process.The emphasis were put using permutation and combination to calculate classical probability.And that the comprehension of the probability itself was ignored.After the study the students can,t understand the stochastic phenomena all around,such as weather forecast, lottery.Due to the conventional teaching methods go adrift the fact,I try to reseach the senior high school probability teaching from mathematics modeling idea.Fistly four aspects of education value are set forth penetrating mathematics modeling idea in probability teaching:The value on training students, practice; The value on training students, mathematics ideation; The value on training students, application consciousness; The value on training students, mathematics interest.Some basic models are divided by teaching reseaches of senior high school probability course and individual understanding:1,Statistics and Probability Model;2,Unattached Test Model;3,Attached Test Model(Not Replacing Ball Model).Afterwards the material examples are given.Finally,three pieces of advice about senior high school probability teaching are brought forward from penetrating mathematics modeling idea in probability teaching: penetrating mathematics modeling idea in probability conception teaching;penetrating mathematics modeling idea in probability exercises teaching;penetrating mathematics modeling idea in probability exercises arranging。The questions about creating related information condition appear frequently in senior high school probability course.Most of them can solve integrating with mathematics idea and method.That the teachers penetrate mathematics modeling idea in this teaching process, makes the students not only taste the probability is not a passage of discrete knowledge,but also feel subtle using mathematics modeling ideas solving real-life problems.
