This project aims to serve the national interest by improving the education of geoscience and environmental professionals in hydrogeology, which focuses on understanding the flow of surface and subsurface water. The nation has a growing need for hydrogeologists to ensure clean and sustainable water sources. As they work to understand and predict the movement of water and other molecules, hydrogeologists must integrate three-dimensional data from maps, wells, and other sources. Research in some STEM disciplines shows that training students in three-dimensional thinking can improve their persistence and retention, especially among women and students of color. However, the specific three-dimensional thinking skills used in hydrogeology have not yet been defined, hampering efforts to train students for hydrogeology careers. This project will explore how expert versus student hydrogeologists use three-dimensional spatial thinking skills to predict the movement of water and contaminants. It will define the critical three-dimensional thinking skills used by professional hydrogeologists to solve water and contaminant flow problems. It will then characterize how students use (or do not use) these skills when learning hydrogeology in the classroom. This information is a critical first step toward creating teaching materials to better prepare a diverse and capable hydrogeologist workforce. Hydrogeology deals with surface and subsurface water flow and the transport and fate of environmental contaminants within those flows. Graduates with hydrogeological training are in high demand in the environmental and geosciences labor market. In addition to requiring specialized knowledge, hydrogeology is a heavily visuospatial discipline that requires practitioners to integrate disparate data from maps, cross-sections, stratigraphic columns, geological and numerical models, well data, water level data, and contaminant concentrations. These data are synthesized to form a three-dimensional model of the subsurface and groundwater flow and contaminant transport. This project seeks to address two research questions: (1) What spatial thinking skills are essential to successfully completing a site characterization and contaminant plume task in hydrogeology? (2) How do students use these skills while completing this task in classroom and field settings? Question 1 will be addressed using a dominantly quantitative, descriptive, cross-sectional expert-novice study in which upper-level undergraduate students, graduate students, and industry and academic experts in hydrogeology complete a suite of spatial thinking and knowledge tests, as well as a site characterization hydrogeology task based on typical classroom exercises. Question 2 will be addressed with a qualitative investigation of how students complete the same hydrogeology task in field and classroom contexts using (or not using) spatial thinking skills identified as essential in Question 1. An external advisory board of experts in cognitive science, geoscience education research, and hydrogeology will advise and provide feedback on the course of the research. Study results will be disseminated in conference presentations and journals. Project deliverables will include identification of specific spatial thinking skills essential to hydrogeology, development of a hydrogeology concept inventory to assess student knowledge, and an evidence-based model of how students use hydrogeology knowledge and spatial thinking to solve water and contaminant flow problems in field and classroom settings.

该项目旨在通过改善水文地质学方面的地球科学和环境专业人员的教育来服务于国家利益，重点是了解地表水和地下水的流动。国家对水文地质学家的需求日益增长，以确保清洁和可持续的水源。当水文地质学家试图理解和预测水和其他分子的运动时，他们必须整合来自地图、威尔斯和其他来源的三维数据。一些STEM学科的研究表明，训练学生的三维思维可以提高他们的持久性和记忆力，特别是在女性和有色人种学生中。然而，水文地质学中使用的具体三维思维技能尚未定义，阻碍了培养水文地质学专业学生的努力。该项目将探讨专家与学生水文地质学家如何使用三维空间思维技能来预测水和污染物的运动。它将定义专业水文地质学家用来解决水和污染物流动问题的关键三维思维技能。 然后，它将描述学生在课堂上学习水文地质学时如何使用（或不使用）这些技能。 这些信息是创建教学材料的关键第一步，以更好地准备多样化和有能力的水文地质工作人员。水文地质学研究地表和地下水流以及这些水流中环境污染物的迁移和归宿。具有水文地质培训的毕业生在环境和地球科学劳动力市场的需求量很大。除了需要专业知识，水文地质学是一门视觉空间学科，需要从业者整合来自地图，横截面，地层柱，地质和数值模型，井数据，水位数据和污染物浓度的不同数据。这些数据被合成，形成一个三维模型的地下和地下水流和污染物的运输。本计画旨在解决两个研究问题：（1）在水文地质学中，什麽样的空间思考技巧对于成功完成场地特性与污染物羽流的任务是必要的？(2)学生如何使用这些技能，同时在课堂和现场设置完成这项任务？问题1将使用主要是定量的，描述性的，横截面的专家-新手研究，其中高层次的本科生，研究生，行业和学术专家在水文地质完成一套空间思维和知识测试，以及网站表征水文地质任务的基础上典型的课堂练习。问题2将与学生如何完成相同的水文地质任务，在现场和课堂环境中使用（或不使用）空间思维技能确定为问题1中必不可少的定性调查。一个由认知科学、地球科学教育研究和水文地质学专家组成的外部咨询委员会将对研究过程提出建议和反馈。研究结果将在会议报告和期刊中传播。项目交付成果将包括确定水文地质学所必需的特定空间思维技能，开发水文地质学概念清单以评估学生的知识，以及学生如何使用水文地质学知识和空间思维来解决现场和课堂环境中的水和污染物流动问题的循证模型。 NSF IUSE：EHR计划支持研究和开发项目，以提高所有学生STEM教育的有效性。 该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
