COVID-19 has created challenges and opportunities across higher education, with flow-on effects for teaching, research, and publishing. Using an archival case study approach, we analyzed 543 Journal of Geoscience Education submissions from 2018 to 2020 to determine potential impacts of the pandemic on our authors and reviewers. Trends in submission numbers and types, gender, and institutional affiliation were characterized pre- and post-COVID onset. Results indicate that though there was an initial drop in submissions post-COVID onset, submission numbers rose to typical levels a few months later. However, the proportion of Curriculum and Instruction submissions dropped by 10% post-COVID onset, whereas research submissions increased by 12.6%, representing a tenfold increase in the gap between the two. In contrast to other studies that found a decrease in submissions by women authors post-COVID onset, JGE had a 3.8% increase in initial submissions by women corresponding authors. However, there was a 12.2% decrease in revisions by women corresponding authors post-COVID onset. Women reviewers had a 2.2% lower acceptance rate post-COVID onset, though still make up over half of JGE's reviewers. Although there were more contributions from corresponding authors at research intensive institutions, reviewers from these institutions had lower acceptance rates post-COVID onset. Review and revision durations both increased post-COVID onset, and reviewer decline reasons became more specific. In response to these findings, we recommend that the geoscience education community continue to be openly understanding of work-life balance, encourage more Curriculum & Instruction scholarship, and support more contributions from authors and reviewers at non-research intensive institutions.

Textbooks are widely used in higher education by instructors and students. Therefore, it is useful to examine how textbooks present information because textbook design impacts how well students learn from them. This study has two parts. First, within the framework of the cognitive load and dual-coding theories, a set of recommendations based on research on how novices learn from printed materials was developed with the goal of establishing a set of best practices to improve student learning. These recommendations include integrating text and figures and minimizing extraneous geologic vocabulary. Any information in printed form, such as textbooks, lab manuals, and informative handouts, could benefit by using these recommendations in their design. Second, a subset of the recommendations was systematically applied to analyze the four introductory geology textbooks with the largest market share. The results of this analysis indicate that students would benefit from textbooks that are more closely aligned with how novices learn best.

Undergraduate research has been shown to be an effective practice for learning science. While this is a popular discussion topic, there are few full examples in the literature for introductory-level students. This paper describes the Geoscience Education Research Project, an innovative course-based research experience designed for introductory-level, nonscience majors. Participating students complete all steps of a scientific research project, starting with the research question, ''What do college students think about ___?'' Students fill in the blank with a geoscience topic of their choosing. Support for the students is ongoing through detailed directions and multiple checkpoint assignments with timely feedback to ensure they are on task. This design and support can be used as a model for other undergraduate research experiences. Student reactions to the benefits of participating in the research project and the effectiveness of its design were analyzed. Students' benefits from this research project included increased content knowledge, improved skills, and positive affective responses, such as interest leading to motivation. In this study, students were also found to have an increased appreciation of science and scientists, without necessarily having the desire to become scientists themselves. Student reactions to the design of the Geoscience Education Research Project emphasized the importance of an appealing topic, careful planning and conveying of project information, frequent deadlines and feedback, and communication by students beyond just the professor. Based on these findings, recommendations for successful implementation of course-based, introductory-level undergraduate research experiences are given.

Although field and research experiences have been shown to help retain students in the geosciences, there is less known about how and why this is the case. We created a field-based research experience for five students with a range of backgrounds and prior experiences. We used mixed methods case study research to identify affect-related persistence factors influencing geoscience interns during a field-based research experience, to interpret how the experience elicited those factors, and to explain why the factors influenced students' intention to persist. The study is framed within the Social Cognitive Career Theory and Geoscience Identity theoretical frameworks. Results indicate that the students in this field-research experience were influenced by five main factors: increasing self-efficacy, discovering people as resources, developing a geoscience identity, making connections with Earth, and maintaining interest. The first three factors have important social aspects to them that were impacted by the design of the field experience. The field experience contributed, positively or negatively, to the students developing the self-efficacy to succeed as a geoscientist and the geoscience identity needed to pursue a geoscience career. Therefore, these affective reactions of the students to the field experience, rather than cognitive reactions, played a key role with regard to impacting their intention to major in the geosciences.

Responding to the need for recruitment and retention of a diverse geoscience population, we developed a capstone homework assignment for use in introductory-level geoscience courses. In this article we present "Geologic Issues: Community Impacts and Science Communication," a place- and problem-based assignment designed using research on student learning and interest, as well as research that suggests underrepresented minority students are more likely to be attracted to science disciplines if they perceive that science can be used to help their communities. The assignment combines a socially relevant problem in a location of personal interest for each student with a short letter-writing assignment designed to help students recognize the value and applicability of the geosciences to their lives. This assignment was successfully implemented in two very different settings--a highly selective four-year college and an open-access two-year college--and to diverse populations of students in small and moderate-sized classes. Students who participated in the study reported positive influences this assignment made on their perceptions of geoscience. For example, the assignment helped them (a) realize that geoscience was pertinent to their community (100% of students); (b) feel more confident in using and communicating science (95% of students); and (c) potentially see themselves as geoscientists because of interest, perception of the value of geoscience, and learning that geoscientists can work in their communities. These results are independent of academic setting, gender, and racial and ethnic diversity, indicating that all groups of students participating in the study benefitted from the assignment.

The rock cycle is a key component of geoscience education at all levels. In this paper, we report on a new guided inquiry curricular module, "Sleuthing through the Rock Cycle," which has a blended online/offline constructivist design with comprehensive teaching notes and has been successful in pilot use in Rhode Island middle and high school classrooms over the past 3 y. The module consists of two overarching activities: (1) SherRock Holmes and the Case of the Mystery Rock Samples, and (2) Cracking the Case of the Changing Rocks. The module encourages hands-on activities, peer collaboration, and real-time teacher review of embedded textual and reflection components. Overall, Rhode Island teachers report that the module is an outstanding teaching tool and that the associated professional development is empowering.

The theory of plate tectonics is the conceptual model through which most dynamic processes on Earth are understood. A solid understanding of the basic tenets of this theory is crucial in developing a scientifically literate public and future geoscientists. The size of plates and scale of tectonic processes are inherently unobservable, necessitating the use of images and models in instruction. To explore plate tectonics conceptions held by undergraduates, we designed and administered a postinstruction survey instrument centered on a common schematic representation of plate tectonics. We report results from a sample of n = 60 nongeoscience majors enrolled in five different introductory Earth-science courses taught at a major research university and a community college. Students held a number of alternative conceptions associated with terminology, plate motion, and plate-related subsurface melting. We also note that some aspects of figures commonly used to teach plate tectonics are problematic for students and may actually result in reinforcement of alternative conceptions. Further work at both the K-12 and college levels directed at innovative approaches to address student conceptions regarding plate tectonics, including designing images that support key scientific messages, is needed. This research can inform curriculum development for entry-level geoscience courses as well as the use of images to convey complex science.

Students do not have a good understanding of how rocks form. Instead, they have many non-scientific alternative conceptions to explain different aspects of rock formation. Using 10 interviews and nearly 200 questionnaires filled out by students at four different colleges, we identified many alternative conceptions students have about rock formation. We then used themes within those alternative conceptions to identify the underlying conceptual barriers that cause them. Conceptual barriers are deeply-held conceptions that prevent students from understanding scientific explanations. One conceptual barrier can cause many alternative conceptions, and alternative conceptions can be the result of more than one conceptual barrier. The seven conceptual barriers identified in the study that prevent students from understanding rock formation are Deep Time, Changing Earth, Large Spatial Scale, Bedrock, Materials, Atomic Scale, and Pressure. Because of these conceptual barriers, students cannot form scientifically correct mental models of how rocks form, resulting in alternative conceptions, so the conceptual barriers need to be overcome before students truly learn the scientific explanations of how rocks form. The results of this study can be applied to other areas of geology in addition to rock formation.
