Micro Experimental Research Based On The Idea Of "Mathematical Situation And Asking Questions"

“Statistics and probability” as one of the four main lines of high school mathematics curriculum content,not only improved the high school mathematics knowledge system,but also can better cultivate students' mathematical literacy.However,in the context of education,classroom teaching still adopts the methods such as “full hall” and “question sea tactics”.The students can not achieve the ideal result in training and development thinking and teaching.Therefore,in the process of mathematics learning,let the students use their existing knowledge and experience,it puts forward and life closely related,is challenging and comprehensive problem,through independent inquiry and cooperation,the formation process of self construction of mathematical knowledge,and cultivate the students' innovation consciousness,solve problems and comprehensive practice ability is very important.In this article,I'm going to go through the literature of statistics and probability,to understand the development of statistics and probability,and to understand the difficulties of the students in this part of the study.Based on the conclusion and the classic questions of this part,we try to find out the current situation of high school students in this part.Investigation result show:(1)Empirical experience can influence students' understand of “statistical and probability”;(2)The connection and difference between “frequency” and “probability”,“mutual exclusion” and “opposites” cannot be deeply understood;(3)There is deviation in the understanding of “equal probability”;(4)The understanding of data digital features is only on the surface,and it is unable to make the right choice for special problems;(5)There are certain problems in the selection of sampling method;(6)Compared with classical generics,the choice of geometric generalization is easy to be confused.And then,in the course of the learning difficulties of these students,I take the “statistics and probability” as a vector,and I'm going to go through the whole “situation and the problem” the teaching mode,the hands-on experience of the “statistics and probability” classroom teaching experience.Using the experimental group and the control group,the evaluation and feedback were carried out through the unified final test,and the combination of theory and practice was achieved.The evaluation shows that “situation-problem” teaching mode has positive and positive effect on students' learning “statistics and probability”.Finally,how to overcome the students' learning disability through teacher teaching is a targeted teaching strategy.
