Physics and Chemistry Education Technology Project

物理和化学教育技术（PhET）项目正在开发一套广泛的在线，高度互动的模拟，支持材料和活动，以改善物理和化学的教学和学习。目前，PhET网站（http：//www.example.com）上有70多个模拟和250多个相关活动可供使用。phet.colorado.edu这些基于网络的资源正在影响大量的学生。目前每年有超过400万个PhET模拟在线运行，数千个完整的网站下载供离线使用。目标是广泛使用PhET的研究工具和资源，将改善美国和世界各地大学和高中学生的物理和化学教育。这个PhET项目结合了一套独特的功能。首先，模拟设计和目标是基于教育研究。其次，使用专业程序员，学科专家和教育研究专家的团队，可以开发涉及技术复杂的软件，图形和界面的模拟，这些都是非常有效的。第三，模拟体现了专家科学家的预测视觉模型，使许多有趣的先进概念变得广泛可用，并揭示了它们与真实的世界的相关性。最后，该项目积极参与研究，以更好地了解模拟的设计和使用如何影响其有效性-例如，调查诸如“这些新技术如何促进学生对复杂科学现象的理解？“和“哪些因素抑制或加强其使用和效力？".

INTERDISCIPLINARY (99)The Physics and Chemistry Education Technology (PhET) Project is developing an extensive suite of online, highly-interactive simulations, with supporting materials and activities for improving both the teaching and learning of physics and chemistry. There are currently over 70 simulations and over 250 associated activities available for use from the PhET website (http://phet.colorado.edu). These web-based resources are impacting large number of students. Per year, there are currently over 4 million PhET simulations run online and thousands of full website downloads for offline use of the simulations. The goal is that this widespread use of PhET's research-based tools and resources will improve the education of students in physics and chemistry at colleges and high schools throughout the U.S. and around the world. This PhET project combines a unique set of features. First, the simulation designs and goals are based on educational research. Second, using a team of professional programmers, disciplinary experts, and education research specialists enables the development of simulations involving technically-sophisticated software, graphics, and interfaces that are highly effective. Third, the simulations embody the predictive visual models of expert scientists, allowing many interesting advanced concepts to become widely accessible and revealing their relevance to the real world. And finally, the project is actively involved in research to better understand how the design and use of simulations impacts their effectiveness - e.g. investigating questions such as "How can these new technologies promote student understanding of complex scientific phenomena?" and "What factors inhibit or enhance their use and effectiveness?".
