Research On Teaching Strategy Of Conditional Probability To Cultivate Core Accomplishment Of Mathematics

In order to meet the needs of social development,the 18 th national congress of the communist party of China(CPC)proposed to implement the requirement of cultivating talents and comprehensively deepen the curriculum reform.With the release of the general framework of Chinese students' development of core literacy,core literacy has become a hot topic in the new round of curriculum reform.The revision group of mathematics curriculum standards in ordinary senior high schools puts forward that the core quality of mathematics is the thinking quality and key ability with the basic characteristics of mathematics,which is needed to adapt to the lifelong development of individuals and the development of society.Mathematics curriculum standards for ordinary senior high schools(2017edition)takes "probability and statistics" as one of the four main lines,running through the entire high school mathematics teaching content.Conditional probability is a difficult point in high school probability teaching.In high school,the teaching of this part should enable students to have a full understanding of the nature of conditional probability knowledge,strengthen the awareness of knowledge application,improve problem solving ability,and cultivate the core quality of mathematics.In this paper,firstly,through the literature analysis,the research on the contents of "mathematics core accomplishment" and "probability teaching" at home and abroad is sorted out to deeply understand the mathematics core accomplishment.Secondly,some high school students and teachers in Nanchong were investigated to understand the current situation of the cultivation of mathematics core literacy.The results showed that the teachers paid more attention to the new curriculum reform,but did not have a deep understanding of the mathematics core quality which was mainly cultivated in the probability teaching.Students have great difficulty in the application of conditional probability knowledge.Students generally believe that the development of mathematics core literacy is average,the development of the best mathematical literacy;Teachers' teaching methods are single,lack of innovation,weak information technology assistance,and few extracurricular activities are carried out.In the constructivism teaching theory and poly a mathematics teaching theory,under the guidance of considering the current status of the cultivation of the core ofmathematics accomplishment,according to the characteristics of the conditional probability teaching content based on the cultivation of the core of mathematics accomplishment,the conditional probability of the new teaching teaching experience concept formation process was proposed,cultivate abstract mathematics accomplishment;Group cooperation to explore,develop logical reasoning literacy;Permeate the thought of model and cultivate the quality of mathematical modeling;Strengthen the training of thinking and cultivate the accomplishment of mathematical operation;Strengthening the awareness of using pictures and cultivating the intuitive imagination literacy are the five teaching strategies.In the conditional probability exercise class,the essence of mathematics is highlighted and the problem is created carefully.Centering on the cultivation of mathematics core literacy,multiple teaching methods are combined.Students are guided to review and summarize the three teaching strategies,and the corresponding teaching design is made for the reference of front-line teachers.Finally,in the concluding part of the paper,the research results of this paper are expounded,the shortcomings of the research are explained,and some prospects for future research are put forward.
