地球科学教师依靠照片,图表和其他可视化来描述在广泛的时间和空间尺度上发生的地质结构和过程。这个概念验证研究测试点击图(COD)的问题,使用课堂反应系统(CRS)管理,作为识别空间误解的研究工具。首先,我们提出了一个分类的空间概念与地球科学概念。其次,我们在本科地质学导论课程中实施了COD问题。每个问题实施三次:教学前,教学后,并在课程结束时,以评估学生的概念理解的稳定性。我们将每个实例分类为:(1)容易纠正的错误信念,(2)没有完全转变的有缺陷的心理模型,或(3)尽管有针对性的指导,但仍然存在的强烈误解。地理信息系统软件有助于对学生的答案进行空间分析。COD数据证实了已知的关于地球结构,地质年代和基准面的误解,并揭示了一种关于热点形成的新的强烈误解。具有复杂空间属性的问题不太可能改变以下指令,更有可能被归类为一个强大的误解。COD问题为学生的概念理解提供了有效的途径。CRS管理的COD问题提供了一个机会,收集大量的学生的空间概念,立即,建立有关学生的误解知识库,并提供反馈,以指导教学。
Geoscience instructors depend upon photos, diagrams, and other visualizations to depict geologic structures and processes that occur over a wide range of temporal and spatial scales. This proof-of-concept study tests click-on-diagram (COD) questions, administered using a classroom response system (CRS), as a research tool for identifying spatial misconceptions. First, we propose a categorization of spatial conceptions associated with geoscience concepts. Second, we implemented the COD questions in an undergraduate introductory geology course. Each question was implemented three times: pre-instruction, post-instruction, and at the end of the course to evaluate the stability of students’ conceptual understanding. We classified each instance as (1) a false belief that was easily remediated, (2) a flawed mental model that was not fully transformed, or (3) a robust misconception that persisted despite targeted instruction. Geographic Information System (GIS) software facilitated spatial analysis of students’ answers. The COD data confirmed known misconceptions about Earth’s structure, geologic time, and base level and revealed a novel robust misconception about hot spot formation. Questions with complex spatial attributes were less likely to change following instruction and more likely to be classified as a robust misconception. COD questions provided efficient access to students’ conceptual understanding. CRS-administered COD questions present an opportunity to gather spatial conceptions with large groups of students, immediately, building the knowledge base about students’ misconceptions and providing feedback to guide instruction.
