Project Summary One of the more challenging aspects of science education for many public elementary school teachers is the lack of a dedicated science laboratory space. Teachers must conduct science experiments in the same room where they will be teaching literature or math in the very next period. For many teachers this severely limits the kinds of experimentation that can occur in the course. By moving experimentation to a Virtual Science Laboratory space (VSL), teachers will be relieved of these logistical challenges and expand the type of experiments that elementary students are able to conduct. The technology offered through the proposed software platform will put students in control of two virtual hands that allow them to naturally coordinate bimanual movements to execute complex tasks in a virtual 3D space in ways that mirror those same tasks in the real-world. By carrying out experiments with their hands, students will learn by doing, absorbing the material more quickly and at a deeper level. The VSL will be developed and validated in three steps: 1. Implement a Virtual Science Laboratory platform that is capable of expressing elementary school physical laboratory lessons. The platform will consist of hardware and software components that support two-handed motion-tracked interaction to let students carry out investigations and experiments in a natural real-world manner. 2. Build a typical lesson in terms of that platform. The core-based lab assignment will directly target the performance expectations of fifth graders to demonstrate grade-appropriate proficiency in planning and carrying out investigations, analyzing and interpreting data, using mathematics and computational thinking, engaging in argument from evidence, and obtaining, evaluating, and communicating information. 3. Determine the effect of the VSL lesson in a live classroom setting and analyze the results. Specifically, the VSL's effectiveness and potential cost savings will be measured by comparing how it conveys the learning material in two classes -- one using the traditional physical lab and the other using the VSL. Assessment of content learning will follow the interaction in addition to assessment of student engagement and enjoyment.

项目摘要 对许多公立小学教师来说，科学教育中更具挑战性的方面之一是 缺乏专门的科学实验室。教师必须在同一个房间里进行科学实验 他们将在下一节课教授文学或数学。对许多教师来说，这严重限制了他们的学习能力。 各种各样的实验。通过将实验转移到虚拟科学 实验室空间（VSL），教师将减轻这些后勤挑战，并扩大类型的 小学生能够做的实验。 通过拟议的软件平台提供的技术将使学生控制两个虚拟的手 这使他们能够自然地协调双手动作，在虚拟3D空间中执行复杂的任务， 这些方法反映了现实世界中的相同任务。通过用手做实验，学生们将 边做边学，更快更深地吸收材料。 VSL将分三个步骤开发和验证： 1.实现一个虚拟科学实验室平台，能够表达小学 物理实验课该平台将由硬件和软件组成， 支持双手动作跟踪互动，让学生进行调查， 以自然的现实世界的方式进行实验。 2.在这个平台上建立一个典型的课程。基于核心的实验作业将直接针对 五年级学生的表现期望，以证明等级适当的熟练程度， 规划和开展调查，分析和解释数据，使用数学和 计算思维，参与证据论证，获取，评估， 交流信息 3.确定VSL课程在现场课堂环境中的效果并分析结果。 具体来说，VSL的有效性和潜在的成本节约将通过比较来衡量 它将学习材料分为两个课堂--一个使用传统的物理实验室， 使用VSL。内容学习的评估将遵循除了评估之外的互动 学生的参与和享受。
