空间技能植根于地球科学的各个方面。空间技能的教学和学习一直是一项具有挑战性但至关重要的努力。为了支持学生在本科课程中学习空间技能，我们使用橡皮泥为中级地球科学课程中的空间相关内容设计了支架，让学生能够建模和操纵地质结构和过程。我们以一学期的地质学课程作为案例研究，探讨了学生报告的橡皮泥如何支持他们在课程中学习地球科学内容的方式。学生们发现橡皮泥对于可视化地质结构（例如断层和圆顶）最有帮助，然后学生可以将其编码到他们的长期记忆或“心理图书馆”中，以便在以后的评估中应用到新的环境中。当学生在课程开始时努力学习介绍性课程内容和技能时，橡皮泥更有帮助。在课程的后期，像预期的那样，对橡皮泥作为脚手架的需求逐渐消失。大多数学生最终寻求新的支架，例如三维块模型，它说明了更复杂和精密的结构和过程。因此，我们认为橡皮泥是学生在空间和地质技能发展的早期阶段的有用支架，因为它可以帮助学生发展这两套技能。它易于使用、价格低廉、便于携带、广泛使用并且为大多数学生所熟悉。
Spatial skills are embedded in all aspects of the geosciences. The teaching and learning of spatial skills has been a challenging, but vital, endeavor. To support student learning of spatial skills in undergraduate courses, we designed scaffolds for spatially dependent content in a mid-level geoscience course using playdough to allow students to model and manipulate geologic structures and processes. Using a semester-long geology course as a case study, we explore the ways in which students reported playdough supported their learning of geoscience content during the course. Students found the playdough most helpful for visualizing geologic structures, such as faults and domes, which students were then able to encode into their long-term memories, or “mental libraries,” for application to new contexts on assessments later. The playdough was more helpful at the start of the course when students were grappling with introductory course content and skills. Later in the course, the need for the playdough as a scaffold faded, as intended. Most students eventually sought new scaffolds, such as three-dimensional block models, which illustrate more complex and sophisticated structures and processes. Therefore, we see playdough as a useful scaffold for students in the early stages of spatial and geologic skill development as it aids students in developing both sets of skills. It is easy to utilize, inexpensive, portable, widely available, and familiar to most students.
