论文部分内容阅读
新课标在各学段中,都安排了四个部分的课程内容:“数与代数”“图形与几何”“统计与概率”“综合与实践”。各部分都有以数学建模的形式来学习和掌握的内容。鉴于初中学生的知识储备不足,社会经验不多等原因,笔者试着在这四个部分的学习中,从教材中提取素材,适时地进行数学建模的教学活动和思想方法的渗透,建立数学模型,解决实际问题。其过程浓缩成“问题的提出,模型的建立,模型的应用”三大步骤,可以适当进行建模准
The new curriculum in each session, are arranged in four parts of the course content: “number and algebra ” “graphics and geometry ” “statistics and probability ” “synthesis and practice ”. Each part has the content that is learned and mastered in the form of mathematical modeling. In view of junior high school students lack of knowledge, social experience and other reasons, the author tries to learn in these four parts, from the material extracted from the material, timely mathematical modeling of teaching activities and ideas and methods of infiltration, the establishment of mathematics Model to solve practical problems. The process of concentration into “question put forward, the establishment of the model, the application of the model ” three major steps, you can properly model
