Rock and mineral labs are fundamental in traditional introductory geology courses. Successful implementation of these lab activities provides students opportunities to apply content knowledge. Inquiry-based instruction may be one way to increase student success. Prior examination of published STEM labs indicates that geology labs, particularly…

The mineral identification lab is typically the entry level college student's initial hands-on introduction to minerals. Our research focused on identifying alternative mineralogy conceptions that students bring to an introductory geology course and investigating the origins and nature of these conceptions. We identified a number of alternative…

The geological sciences, technology, engineering, and mathematics (geo-STEM) have the capacity to investigate and address geological and environmental challenges. Many of these challenges (e.g., pollution, flooding, and slope failure) unjustly impact lower socio-economic communities in urban and rural settings where there is limited access to…

Spatial reasoning ability is key to an individual's understanding of geology and geosciences more broadly. One reason why is because spatial ability allows individuals to use multiple external representations (MERs) to understand information that they cannot normally interact with directly, such as the Earth. This article presents results from two…

Calls have been made to determine optimal learning progressions for geology students so that best practices for teaching content knowledge and skills during an undergraduate degree can be determined. To address these calls, there first needs to be understanding of what courses are required. This study was conducted to provide a systematic…

Geological skills such as interpreting outcrops are often taught during fieldwork. However, recent advancements in digital technologies and the demand for more inclusive and accessible learning has provided an opportunity to teach these skills in virtual field trips (VFT). The Iceland VFT was developed to teach students about volcanic features and…

Scaled analog modeling ("sandbox modeling") allows deformational processes, such as the development of a mountain belt, to be observed in real time in a classroom setting. However, the actual learning gains from exposure to sandbox modeling in geology courses in higher education settings have not been explicitly studied. We begin to…

Recent studies have identified an incomplete student understanding of how elastic rebound causes earthquakes. We hypothesized that realistic imaging of spatial patterns in ground motions over the course of the earthquake cycle would improve student understanding. Incorporating spatial change information in the form of both motion vectors and…

Teamwork has been identified as an essential employability skill and learning outcome in the geosciences, especially during fieldwork. Although specific teamwork skills have been identified in prior research, few studies to date have addressed how students develop or use these skills during their educational preparation in science, technology,…

Triggered situational interest in introductory courses can encourage student engagement, motivation, and value for the geosciences. In-person labs have traditionally played a unique role in triggering situational interest compared to lectures, but the COVID transition online disrupted these dynamics. We examine students' self-reported situational…

Across the landscape of higher education, the COVID-19 pandemic has caused fundamental changes at a variety of scales. To understand which aspects of higher education instruction at the departmental (meso-scale) level were most and least impacted by the COVID-19 pandemic, chairs of geoscience departments at public higher education institutions in…

This paper describes how plate tectonics and rock genesis, two topics that are typically addressed separately in secondary Earth science classes, can be taught together as an integrated system. We define the TecRocks Reasoning Framework, developed to support student reasoning about rock formation situated in the context of plate tectonics. We also…

Conventional letter- or number-based grading systems, though ubiquitous at all levels of education, do not optimize the learning experience. The philosophy of "ungrading" includes a variety of approaches that decenter or even remove numeric or letter scoring of student work in favor of descriptive feedback, opportunities for revision,…

Self-regulated learning (SRL) models provide a framework for understanding the observed variance of student performance in geoscience learning contexts. Instructors can potentially use a SRL framework to support students in self-identifying the specific approaches to learning they use when engaging in geoscience learning situations (coursework,…

Sequence stratigraphic and Wheeler diagram interpretations require a strong combination of conceptual understanding and diagram reasoning skills. Students are generally exposed to the foundational concepts within sequence stratigraphy (relative sea level, eustasy, base level, and accommodation) in a variety of courses along their degree path,…
