摘要
数学建模是高中数学六大核心素养之一,通过数学建模教学活动,可以提高学生分析问题、解决实际问题的能力,促进学生思维品质发展。以三角函数模型为为例,依托"货船进出港时间问题",对数学建模教学按照数学建模的基本流程进行了精心设计,试图通过本模型对数学建模的教学一般过程和特征进行分析,达到培养学生数学建模素养的目的。同时依据数学建模素养水平划分对数学建模的评价做了说明,并提出了以下启示:"数学建模教学的关键在于科学选取素材;建模活动要凸显数学核心素养培育;根据数学建模素养水平划分,建立科学评价体系"。
mathematical modeling is one of the six core qualities of high school mathematics. Through teaching activities of mathematical modeling, it can improve students 'ability to analyze problems, solve practical problems, and promote the development of students' thinking quality. Taking the trigonometric function model as an example, relying on the "time of cargo ship entering and leaving Hong Kong", the article carefully designed the mathematics modeling teaching according to the basic process of mathematical modeling, and tried to analyze the general process and characteristics of mathematics modeling through this model. To achieve the goal of cultivating students 'mathematical modeling literacy. At the same time, according to the level division of mathematical modeling literacy, the evaluation of mathematical modeling is explained, and the following enlightenment is proposed: "The key of mathematics modeling teaching lies in the scientific selection of materials; Modeling activities should highlight the cultivation of mathematical core literacy; According to the level of mathematical modeling literacy, establish a scientific evaluation system. "
