Explaining phenomena associated with a system involves describing a system's structure and articulating the process through which the system's structure changes over time. This paper defines geo-sequential reasoning in the context of plate tectonics and uses it to analyse how students explain the geological processes that occur along convergent…

This text is a simultaneously personal and political commentary on those who inhabit the border between worlds, such as those now at war in a viral assemblage. Starting from a general intention of shifting curricular responses away from instrumental and technical solutions toward cultivating the ability to act and think in times of uncertainty,…

Simple energy balance models of planetary systems are of fundamental importance to understanding equilibrium temperatures. Most textbooks that discuss energy balance take a further step and include the effects of an atmosphere on the surface temperature. It is noticeable, however, that in such discussions of planetary surface energy balance some…

In this article, we describe two large-scale, professional development programs that are grounded in communities of practice in the geosciences. Each program uniquely fostered leadership skills among the participants, and many community college instructors emerged as leaders on their campuses and beyond.

Mathematics is a common component of many science and social science degrees, but frequently not considered a prerequisite for their study. This can lead to some students studying mathematics components at undergraduate level with little or no previous mathematical learning and varying levels of motivation, or desire, to study mathematics. This…

Undergraduate summer field programs are valuable experiences that can foster or reduce students' self-efficacy, an important factor in students' success and retention in geoscience. Growing research findings show that science field experiences can be hostile and unwelcoming to students with marginalized identities, which may negatively impact…

The purpose of this study is to determine the spatial thinking ability of high school students using indicators from Sharpe-Huynh model. These indicators include analysis, spatial interaction, scale, representation, comprehensiveness, and application. Furthermore, this study examined the effect of Earthcomm learning on student's spatial thinking…

In this paper, we dwell amongst what was agitated from enacting Neimanis' (2012) hydrofeminism in an 'aqueous-body-writing-reading' experiment that unfolded in discrete but entangled locations (London and Cape Town) to actively disrupt and reformulate ideas about what it is to do scholarly work. We consider how we might dislodge anthropocentric…

Providing pathways that support geoscience transfer students from two-year colleges (2YC) to four-year colleges and universities (4YCU) addresses enrollment challenges, diversity, equity, and inclusion issues, and helps build the 21st-century geoscience workforce. Building bridges between 2YC-4YCU programs can happen in various ways, all of which…

As one of the STEM disciplines with the lowest percentages of minoritized students and professionals, faculty and administrators in the geosciences have an opportunity to address racism within the context of their classrooms and campuses. In response, a group of community college geoscience faculty from disparate institutions across the U.S. came…

Several properties of Earth's magnetic field (field vectors, time dependence) are measured in various locations using a smartphone/tablet magnetic sensor. To enable a proper use of the magnetic sensor as a classroom tool, the exact location of the sensor in the device and its resolution must be identified in a first step. Then, students may…

The purpose of this research was to explore the coherence and effectiveness of an assessment approach that combined principles of cognitive-based assessment, performance assessment, and the Next Generation Science Standards. By drawing on research on learning progressions and cognition in geoscience to design, implement, and analyze an Earth…

O•, O[subscript 2] and O[subscript 3] play vital roles in the Earth's atmosphere, regulating ultraviolet radiation from the Sun and being essential for life. However, the oxygen family, O•, O[subscript 2] and O[subscript 3], also provides a source of the HO radical, the atmospheric detergent that removes pollutants from the atmosphere. This…

The epistemic components of science are included in instruction through the three-dimensional learning of the Next Generation Science Standards (NGSS). Students use the Science & Engineering Practices to engage the Disciplinary Core Ideas through the perspective of the Crosscutting Concepts. The NGSS focus on the epistemic aspects that all…

The reliance on online learning systems has increased during the COVID-19 epidemic to maintain education. The effectiveness of online life and earth science instruction is assessed in this study which involves 150 first-year high school students. Methodologically, it juxtaposes elearning with traditional classroom teaching across various…
