Abstract. Managing uncertainty is fundamental to geoscience practice, yet geoscience education generally does not incorporate explicit instruction on uncertainty. To the extent that students are exposed to scientific uncertainty, it is through in-person field experiences. Virtual field experiences – which rely on pictures, maps, and previously collected measurements – should therefore explicitly address uncertainty or risk losing this critical aspect of students' experience. In this paper we present a framework for teaching students to assess and communicate their uncertainty, which is grounded in best expert practices for conveying uncertainty and familiar terms-of-art in geology. The starting point of our framework is the recognition of uncertainty in both geologic data and models, the latter of which we use as an encompassing term to refer to potential geological processes and structures inferred on the basis of incomplete information. We present a concrete application of the framework to geological mapping and discuss how it could enhance student learning in both traditional in-person and virtual experiences. Our framework is extensible in that it can be applied to a variety of geologic features beyond those where uncertainty is traditionally assessed, and can also be applied to geological subdisciplines.

不确定性教学:用于交流传统和虚拟领域经验中的未知因素的新框架

摘要。管理不确定性是地球科学实践的基础,但是地球科学教育通常不包含有关不确定性的明确指导。在一定程度上,学生要面对现场的科学经验,这会给他们带来科学的不确定性。因此,虚拟实地经验(依赖于图片,地图和以前收集的测量值)应明确解决不确定性或冒失去学生体验这一重要方面的风险。在本文中,我们提供了一个框架,用于教给学生评估和传达其不确定性的基础,该框架以最佳专家实践为基础,以传达不确定性和熟悉的地质学术语。我们框架的起点是认识地质数据和模型中的不确定性,我们将后者作为一个笼统术语,指的是根据不完整信息推断出的潜在地质过程和结构。我们介绍了该框架在地质制图中的具体应用,并讨论了如何在传统的面对面和虚拟体验中增强学生的学习。我们的框架具有可扩展性,因为它可以应用于除传统上评估不确定性的那些地质特征之外的各种地质​​特征,也可以应用于地质子学科。
