利用GeoGebra和“PBL”模式进行数学建模研究一例

A Case Study of Mathematical Modeling Using GeoGebra and “PBL” Model

《普通高中数学课程标准(2017年版2020年修订版)》中明确将“数学建模”列为数学学科六大核心素养之一,数学建模搭建了数学与外部世界联系的桥梁,是数学应用的重要形式。数学建模是应用数学解决实际问题的基本手段,也是推动数学发展的动力。但在数学课堂教学中数学建模如何开展仍然是一线数学教师非常关注并难以实施的问题,这里利用GeoGebra数学软件并借鉴项目学习框架,以探究茶水的最佳饮用时间为例提供了一个具体的教学设计。

“Mathematics modeling” is clearly listed as one of the six core qualities of mathematics in the general high school Mathematics Curriculum Standards (2017 edition, 2020 revision edition). Mathematical modeling builds a bridge between mathematics and the outside world, and is an important form of mathematical application. Mathematical modeling is the basic means of applying mathematics to solve practical problems, and it is also the driving force to promote the development of mathematics. However, how to carry out mathematical modeling in mathematics classroom teaching is still a problem that front-line mathematics teachers are very concerned about and difficult to implement. Here, GeoGebra mathematics software and project learning framework are used for reference to provide a specific teaching design to explore the best drinking time of tea as an example.
