项目摘要

Atmospheric Sciences (41)A visually-realistic virtual tornadic supercell thunderstorm is being developed with data probe capabilities, providing students from K-12 through graduate with opportunities to learn as scientists learn in a constructivist manner. The virtual storm is a proof-of-concept for later creation of other virtual geoscience systems. The virtual storm addresses the NSF goal of providing all students access to excellent undergraduate science education, with learning based upon direct experience with methods and processes of inquiry. This research is being built upon a simple prototype of the virtual storm, already developed with internal funds at Iowa State University. Although the prototype storm, lacking data probe capabilities, was developed in a fully-immersive virtual CAVE, a version has been disseminated to linux-based PCs, improving student access. We are creating a Windows-based version for wider dissemination. The numerous small-scale details within a super cell thunderstorm that reflect the wide range of important atmospheric processes occurring make the storm an especially useful model to serve as a proof-of-concept. An assessment of the impact the virtual storm has on science education is being made by comparing student answers to questions on the topic in a large-lecture introductory course in year 1 (no exposure to the virtual storm) to those from year 2 when students are exploring the virtual storm. Successful completion of the project should demonstrate that exciting laboratory-type experiences of phenomena previously off limits to students within classroom laboratories can be brought to students everywhere by virtual reality simulations.

大气科学（41）正在开发一种具有数据探测能力的视觉逼真的虚拟龙卷风超级单体雷暴，为从K-12到研究生的学生提供学习的机会，因为科学家们以建构主义的方式学习。虚拟风暴是为以后创建其他虚拟地球科学系统的概念验证。虚拟风暴解决了NSF的目标，即为所有学生提供优秀的本科科学教育，学习基于直接经验的方法和过程的调查。这项研究是建立在一个简单的原型虚拟风暴，已经开发了内部资金在爱荷华州州立大学。虽然原型风暴，缺乏数据探测能力，是在一个完全沉浸式的虚拟洞穴开发的，一个版本已经传播到基于Linux的PC，提高学生的访问。我们正在创建一个基于Windows的版本，以便更广泛地传播。超级单体雷暴中的许多小尺度细节反映了发生的广泛的重要大气过程，使风暴成为一个特别有用的模型，可以作为概念验证。虚拟风暴对科学教育的影响的评估正在通过比较学生的回答问题的主题在一个大型讲座介绍课程在第1年（没有接触到虚拟风暴），从第2年的学生正在探索虚拟风暴。该项目的成功完成应该表明，以前禁止学生在教室实验室内进行的令人兴奋的实验室类型的现象体验可以通过虚拟现实模拟带给各地的学生。
