PhET互动仿真程序在中学数学教学中的应用
The Application of PhET Interactive Simulation in the Middle School Mathematics Teaching

PhET互动仿真程序是一款开源、互动游戏式的学习软件，旨在通过免费的互动模拟平台推动全球科学和数学教育的发展，其中与应用数学相联系的程序是拓展中学数学教学路径的切入点。本文归纳总结PhET仿真平台的特点，探讨PhET互动仿真程序应用价值，挖掘PhET在应用与开发过程中与元认知提示语相联系的创新点，并将其在中学数学中的应用(以《任意角的三角函数概念》和《二项分布》为例)进行详细解释说明。PhET互动仿真程序能够促进学生对抽象知识的本质理解，培养数学应用意识，拓展应用数学思维，提升数学核心素养与关键能力的发展，为跨学科教育与中学数学相融合提供了新的思路，为信息技术与教育相融合提供了一条可行的实践路径。
The PhET interactive simulation is an open source, interactive game learning platform, which aims to promote the development of global science and mathematics education through free interactive simulation. The simulation associated with applied mathematics provides a perfect introduction to expand the path of mathematics teaching in middle schools. In this study, the characteristics of PhET simulation were induced and summarized, the application value of PhET simulation was dis-cussed, and the innovation of PhET related to metacognitive prompts was explored. What’s more, the application of PhET interactive simulation program in middle school mathematics (take “The Concept of Trigonometric Function at Arbitrary Angle” and “Binomial Distribution” as examples) was explained in details. PhET interactive simulation is able to facilitate students’ understanding of the essence of abstract knowledge, develop mathematics application awareness, expand applied mathematical thinking and cultivate the development of mathematics core literacy and key abili-ties. Further, it can provide new ideas for the integration of interdisciplinary education and middle school mathematics, and a feasible practical path for the integration of information technology and education.
