This collaborative project is investigating the characteristics of a mixed-reality learning environment that combines the rich context and multi-sensory experiences of a physical lab with the interactive simulations of a virtual lab. The hybrid environment integrates sensors and simulations to bring out the advantages of each setting in a complementary way. The research team is developing four such mixed-reality laboratory experiences for secondary school level chemistry and physics courses and studying student learning in these contexts. Two of the activities use an integration strategy in which data acquired in real time from a physical experiment are used to control a virtual experiment. The advantage of this coupling is that abstract concepts or invisible processes can be visualized on the computer screen while the physical experiment is underway. Whenever the learner's hands-on interaction with the physical experiments changes the sensor measurement, the visualization in the virtual experiment responds accordingly, creating an intimate link between the two worlds. The other integration strategy uses physical and virtual experiments in parallel, challenging the student to match the results measured by the sensors and the results computed by the simulations. The learning potential in this configuration stems from the ability to go back and forth between both worlds, adjusting the virtual experiment to match the physical experiment and then adjusting the physical experiment to test the fidelity of the virtual experiment. Implementations of the four activities in eight classrooms are being compared to classes covering similar content. The intellectual merit of this project lies in its investigation of the potential of cyberlearning technologies to transform inquiry in the lab. In addition, the project brings to bear the expertise of a recognized team of researchers. The project is exercising its broader impacts through its identification of a new instructional approach to STEM education. The combination of physical and virtual labs carries the potential for broad utility, with the insights and examples developed by this project potentially applicable throughout STEM education. In fact, because all of the project software is open source and the materials made available freely from the project's website, the only expenses to schools are for the sensors. A key design criterion is that all project software is compatible with sensors from multiple vendors so that schools are not limited in their choices.

该合作项目正在研究混合现实学习环境的特征，该环境将物理实验室的丰富环境和多感官体验与虚拟实验室的交互式模拟相结合。混合环境集成了传感器和模拟，以互补的方式发挥每种设置的优势。研究团队正在为中学化学和物理课程开发四种此类混合现实实验室体验，并研究学生在这些背景下的学习情况。其中两项活动使用集成策略，其中从物理实验实时获取的数据用于控制虚拟实验。这种耦合的优点是，在物理实验进行时，抽象概念或看不见的过程可以在计算机屏幕上可视化。每当学习者与物理实验的动手互动改变传感器测量值时，虚拟实验中的可视化就会做出相应的响应，从而在两个世界之间建立密切的联系。另一种集成策略并行使用物理和虚拟实验，要求学生将传感器测量的结果与模拟计算的结果相匹配。这种配置中的学习潜力源于在两个世界之间来回的能力，调整虚拟实验以匹配物理实验，然后调整物理实验以测试虚拟实验的保真度。正在将八个教室中四项活动的实施情况与涵盖类似内容的班级进行比较。该项目的智力价值在于它对网络学习技术改变实验室探究的潜力进行了调查。此外，该项目还拥有公认的研究团队的专业知识。该项目通过确定 STEM 教育的新教学方法来发挥更广泛的影响。物理实验室和虚拟实验室的结合具有广泛实用的潜力，该项目开发的见解和示例可能适用于整个 STEM 教育。事实上，由于所有项目软件都是开源的，并且可以从项目网站免费获取材料，因此学校唯一的费用就是传感器的费用。一个关键的设计标准是所有项目软件都与多个供应商的传感器兼容，以便学校的选择不受限制。
