9451774布朗当前的学习理论表明，通过创造一种学习环境，使学生能够专注于与有用的抽象直接相关的物理现象，根据他们的概念模型做出预测，并根据他们的概念模型得到即时的互动反馈，并与其他学生合作做出这种预测和讨论意想不到的结果，可以大大提高学生在物理科学方面的有效学习。本项目的目的是通过使用一些技术工具，为物理实验室教学创造这样一个学习环境。具体而言，该项目将结合图像处理和视频捕捉技术来创建运动和光学实验室实验，使学生能够将概念模型的视觉和图形表示与现实世界的现象联系起来。学生将观看并与实时处理的视频图像进行交互，以增强或测量重要特征。学生还将用学生绘制的解释和预测、图像测量工具和模型模拟生成的图形叠加捕获的视频图像和剪辑。这个创新项目对学生有很多好处，其成果将广泛传播给社区学院和大学的物理和科学教师。

9451774 Brown Current learning theory indicates that effective student learning in the physical sciences can be greatly enhanced through the creation of a learning environment that enables students to focus on physical phenomena that are directly linked to useful abstractions, to make predictions based on their conceptual models which receive immediate interactive feedback, and to collaborate with other students in making such predictions and discussing unexpected results. The aim of the proposed project is to create such a learning environment for physics laboratory instruction through the use of a number of technological tools. Specifically, the project will combine image processing and video capture technologies to create motion and optics lab experiments which enable students to link visual and graphical representations of conceptual models with real-world phenomena. Students will view and interact with live video images which are processed in real time to enhance or measure important features. Students will also overlay captured video images and clips with student-drawn interpretations and predictions, image measurement tools, and graphics generated by model simulations. This innovative project has numerous benefits for students and the results will be widely disseminated to community college and university physics and science instructors.
