【摘要】 本文是对课程教学的新探索,根据新版课程标准对概率内容的要求,紧密结合学生的学习特点,提出在PBL模式下的高中概率内容教学实践的研究问题,通过实践以期达到提升高中概率教学质量的目的,并为高中概率内容的教学提供新思路。本文将PBL教学模式与高中概率内容联结在一起,从理论研究和实践教学两个方面出发,对如何在高中概率内容的教学中引入PBL模式进行研究。笔者围绕研究课题查阅相关的文献资料,并对已有的研究成果进行梳理,在分析PBL的研究现状及文献资料的基础上,对PBL模式的含义、理论基础、特征、实施标准等方面进行阐述,并在PBL设计和实施标准的指导下对PBL教学模式在高中概率内容上的应用过程进行详细叙述,其中包括高中概率内容的分析、教学目标的制定、教学过程的实施以及最后的教学评价。并选取高中概率内容进行PBL模式下的教学实践,在本文中以几何概型和独立重复试验与二项分布为案例,详细讲解在PBL教学模式下如何设置高中概率内容的教学目标以及如何设计教学环节来引导学生建构知识,在实验后利用测试题和调查问卷来分析学生的学习水平,以此研究PBL模式下的概率教学效果。研究结果表明,PBL模式下的高中概率内容教学在创设真实的问题情境中能够建立知识与现实生活的联系,将基础知识应用于实际生活,可以引起学生对问题的探索欲望,以此调动学生的学习兴趣,培养学生解决问题的能力。在小组合作的过程中,充分发挥学生的主观能动性,通过相互交流认识到自身的不足,在提高理解能力的同时加深学生对数学问题的认识程度,使学生的创新能力得到提高。因此,PBL教学模式还可应用到更多与实际相关的领域,在以后的教学实践研究中将继续完善。更多还原

【Abstract】 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.更多还原
