Learning physics by practicing it with physical apparatus or using interactive video: is there a difference?

这个项目将促进学生在使用在线资源时如何发展科学推理能力的理解。教育正在从传统的教室和实验室迅速转变为更灵活的在线学习环境，在这种环境中，学生并不总是能够接触到物理设备。研究表明，学生可以通过协作实践的调查经验以及随后的分析和讨论来学习科学能力。这个项目将探索使用高质量的实验互动视频来培养同样的科学能力的程度。该项目将基于网络的视频技术的灵活性与调查科学学习环境(ISLE)相结合，ISLE是一个教学框架，引导学生完成实践科学家使用的科学推理过程。ISLE框架通常是在讲课与以仪器为基础的实验室实验分开的传统环境中实施的，已经被证明可以提高学生的科学推理能力。今天，电子学习资源，如该项目的基于视频的小岛(VISLE)，正在模糊讲座和实验室之间的界限，并为在非传统环境中进行真正的科学研究打开了可能性。该项目的目标是：a)更深入、更细致入微地了解学生如何使用诸如VISLE之类的电子学习资源参与科学实践。学生是否使用VISLE学习基本物理原理？使用VISLE他们展示和发展了哪些科学推理能力或思维习惯？以及b)了解如何利用视频的优势将真实的科学调查扩展到非传统场所(如课堂或家庭作业)。

This project will advance understanding of how students develop scientific reasoning abilities when using an online resource. Education is shifting rapidly from traditional classrooms and laboratories to more flexible, online learning environments in which students do not always have access to physical equipment. Research has shown that students can learn scientific abilities through collaborative hands-on investigative experiences and subsequent analyses and discussions. This project will explore the extent to which those same scientific abilities can be developed using high-quality interactive videos of experiments.This project will couple the flexibility of web-based video technology with the Investigative Science Learning Environment (ISLE), a pedagogical framework that leads students through processes of scientific reasoning used by practicing scientists. The ISLE framework, most often implemented in a traditional setting where lecture is separated from apparatus-based lab experimentation, has already been shown to improve students' scientific reasoning abilities. Today e-learning resources such as this project's video-based ISLE (vISLE) are blurring the lines between lecture and lab and opening up the possibilities for authentic scientific investigations in non-traditional settings. The goals of this project are: A) to gain a deeper and more nuanced understanding of how students engage in science practices using an e-learning resource such as vISLE. Do students learn fundamental physics principles using vISLE and what scientific reasoning abilities or habits of mind do they display and develop using vISLE? and B) to gain an understanding of how the advantages of videos can be exploited to extend authentic scientific investigations into non-traditional venues (such as in the classroom or in a homework assignment).
