Research On Teaching Practice Of High School Probability Content In PBL Mode

This paper is a new exploration of curriculum teaching.According to the requirements of the new curriculum standards for probabilistic content,closely combined with the students' learning characteristics,this paper puts forward the research problems of high school probability content teaching practice under PBL mode,and aims to improve the quality of high school probability teaching through practice.The purpose and provide new ideas for the teaching of high school probability content.This paper links the PBL teaching mode with the high school probability content.From the two aspects of theoretical research and practical teaching,this paper introduces how to introduce the PBL model in the teaching of high school probability content.The author reviews the relevant literatures around the research topics,and combs the existing research results.Based on the analysis of the research status and literature of PBL,the author expounds the meaning,theoretical basis,characteristics and implementation standards of PBL model.Under the guidance of PBL design and implementation standards,the application process of PBL teaching mode in high school probability content is described in detail,including the analysis of high school probability content,the development of teaching objectives,the implementation of teaching process and the final teaching evaluation.The high school probability content is selected for the teaching practice in PBL mode.In this paper,the geometric probabilities and independent repetitive experiments and binomial distribution are taken as examples to explain in detail how to set the teaching objectives of high school probability content and how to design teaching in PBL teaching mode.The link guides the students to construct knowledge,and uses the test questions and questionnaires to analyze the students' learning level after the experiment,so as to study the probability teaching effect under the PBL mode.The research results show that the high school probability content teaching in PBL mode can establish the connection between knowledge and real life in the creation of real problem situations,and apply the basic knowledge to real life,which can arouse students' desire to explore problems and mobilize students.Learn interest and develop students' ability to solve problems.In the process of group cooperation,give full play to the subjective initiative of students,realize their own deficiencies through mutual communication,and deepen students' understanding of mathematics problems while improving their understanding ability,so that students' innovative ability can be improved.Therefore,the PBL teaching model can be applied to more practical areas,and will continue to be improved in future teaching practice research.
