Geology (42)Visualization and spatial thinking are fundamental skills across the STEM fields. Digital outcrop models (DOMs) created with emerging technologies such as ground-based lidar (light detection and ranging) laser scanning are the basis of a major new advance in the geosciences, but we currently lack a full understanding of how such resources can be used as learning aids to support visualization and spatial thinking. This project is addressing this knowledge gap by studying the effectiveness of advanced visual aids in earth science education. Three-dimensional, interactive DOMs are being used to create several learning modules. An existing DOM of the Eocene Green River Formation in Utah is being used for the initial phase of research, and is complemented by additional lidar scanning to take advantage of recent critical advances in this technology. The learning exercises are being implemented in introductory level geology classes, and their utility is being measured by tracking student progress in visualizing geologic relations and improved conceptual understanding. A model for interdisciplinary collaboration is being established. The learning modules, with supplementary documentation for faculty users, are available in a standard freeware format via the internet (e.g., the National Science Digital Library). Assessment results are being disseminated and shared within the STEM, visualization, and geoscience education communities through publications and a topical session at a major national meeting. It is predicted that successful integration of uniquely interactive, photo-realistic DOMs with more traditional field methods and teaching approaches can improve the learning experience for large and diverse student groups in a range of classroom settings.

地质学 (42) 可视化和空间思维是 STEM 领域的基本技能。使用地面激光雷达（光探测和测距）激光扫描等新兴技术创建的数字露头模型（DOM）是地球科学重大新进展的基础，但我们目前对如何使用这些资源缺乏充分的了解作为支持可视化和空间思维的学习辅助工具。该项目通过研究先进视觉辅助工具在地球科学教育中的有效性来解决这一知识差距。三维交互式 DOM 被用来创建多个学习模块。犹他州始新世格林河地层的现有 DOM 正在用于研究的初始阶段，并通过额外的激光雷达扫描进行补充，以利用该技术的最新关键进展。学习练习正在入门级地质学课程中实施，其效用是通过跟踪学生在可视化地质关系和改进概念理解方面的进展来衡量的。 跨学科合作的模式正在建立。学习模块以及供教师用户使用的补充文档可以通过互联网以标准免费软件格式获取（例如国家科学数字图书馆）。评估结果正在通过出版物和大型全国会议上的专题会议在 STEM、可视化和地球科学教育社区内传播和共享。据预测，独特的交互式、逼真的 DOM 与更传统的现场方法和教学方法的成功整合可以改善各种课堂环境中大型且多样化的学生群体的学习体验。
