Investigation Of Students' Random Thinking Development Level In Probability Teaching Situation

Because of the uncertainty of the object probability studies,it is necessary to develop students' random thinking to understand.Prior to this,students contact with mathematics for the deterministic mathematical problems,always with deterministic mathematical thinking to look at mathematical problems.Since the particularity of probabilistic thinking,we need to guide students to change from certainty to uncertainty,which leads to the difficulty of teaching.Therefore,this paper aims to improve the probabilistic teaching effect and improve the students' random thinking ability by setting the probabilistic teaching situation to study the development of random thinking of senior high school students.The results show that:(1)Reasonable probability situation is helpful to the development of students' random thinking;(2)The lack of probability situation makes the problem solving ability weak;(3)The lack of probability situation makes probability model is not in place.Finally,on the basis of the research conclusion,this paper puts forward the suggestion of probability teaching for reference.(1)Pay attention to the application of probability situation;(2)Experience probability process;(3)Inductive probability model.
