数学建模就是建立数学模型。数学建模是一种数学的思考方法,是运用数学的语言和方法,通过抽象、简化建立能近似刻画并“解决”实际问题的一种强有力的数学手段。建模过程从学习主体来看,应是学生主动、积极探究的过程;从数学思维的角度来看,应是分析综合抽象概括推理的过程。学生在数学建模的过程中,需要运用数学概念和数学的思想方法,以及已经习得的学习经验。经历建模活动,学生能够习得建模的方法,积累更多的学习经验,提高解决问题的能力。主要以三角形的面积(练习课)为例谈谈数学建模思想在练习课中的应用。
Mathematical modeling is to establish a mathematical model. Mathematical modeling is a mathematical way of thinking that uses mathematical language and methods to simplify and establish a powerful mathematical tool that approximates and “solves” real problems through abstraction. The modeling process should be the process of active and active inquiry from the main body of learning. From the perspective of mathematical thinking, it should be the process of analyzing general abstract reasoning. Students in the mathematical modeling process, the need to use mathematical concepts and mathematical thinking, as well as the learning experience has been acquired. Experience modeling activities, students can learn modeling methods, accumulate more learning experience, improve the ability to solve problems. Mainly to the area of the triangle (practice class) as an example to talk about the application of mathematical modeling in practice class.
