Virtual and Physical Laboratories for Active Learning of Electronic Materials

本项目为本科电子材料课程开发一个基于网络的主动学习工具包，其中包含课程模块。目前网络在工程和科学课堂上的应用是传统教科书学习方法的有限扩展。相比之下，这个项目建立了一个开发虚拟实验室实验的框架，以解决学生的不同学习风格，并在不同的抽象层次上呈现信息。在电子材料课程中，这些虚拟实验与传统的动手实验相结合。教育上的挑战是帮助大学生培养对电子如何在晶体内运动，它们如何相互作用，以及它们如何受到施加的电压，光和热的影响的直觉。与许多仅仅是教科书页面动画的教育小程序不同，我们使用基于线性响应理论和玻尔兹曼输运方程的模拟。这使学生可以探索许多电子传递现象的微观起源，而无需理解高级研究生课程中通常涉及的复杂数学。这项技术演示了如何使用Web来弥合讲座和实验室之间的差距，接触到具有不同学习风格的学生，并促进课堂环境中的主动学习。

Engineering - Electrical (55)This project is developing a Web-based active learning toolkit with course modules for undergraduate electronic materials coursework. Current applications of the Web to engineering and science classes are fairly limited extensions of traditional textbook approaches to learning. In contrast, this project builds a framework for developing virtual laboratory experiments that address the different learning styles of students, and presents information at various levels of abstraction. These virtual experiments are integrated with traditional hands-on laboratory experiments in a course in electronic materials. The educational challenge is to help undergraduates develop intuitions about how electrons move inside a crystal, how they interact with each other, and how they are affected by applied voltage, light and heat. In contrast to many educational applets, which are merely animations of the pages of the textbook, we use simulations based on the linear response theory and Boltzmann transport equation. This allows students to explore the microscopic origin of many electron transport phenomena without understanding the sophisticated mathematics typically covered in an advanced graduate course. This technology demonstrates how the Web can be used to bridge the gap between lectures and laboratories, reach students with different learning styles, and facilitate active learning in a classroom context.
