Title: ET cool home: innovative educational activities on evapotranspiration and urban heat
Abstract. Teaching evapotranspiration (ET) in university courses often focuses on either oversimplified process descriptions or complex empirical calculations, both of which lack grounding in students' real-world experiences and prior knowledge. This calls for a more applied approach to teaching about ET that connects concepts to experience for improved educational outcomes. One such opportunity exists at the intersections between ET and heat in cities, where a growing majority of the world's population lives, including many of our students. In this work we describe an ET educational activity that integrates theory with practical design, taking advantage of the close link between ET processes and urban heat patterns. In a benchtop experiment, students measure ET variations across common land surfaces (e.g., asphalt, grass, and mulch) through water and energy balance approaches. The experiment is paired with an “urban heat tour” in the campus environment, facilitated by portable infrared cameras, offering firsthand observation of urban heat patterns. These two activities, together, provide context in which students can understand the difference in ET across various land covers, describe the relationship between ET and land surface temperatures, and explain the impacts of urban design on heat dynamics. The activities are adaptable to serve a diversity of student backgrounds and to different educational contexts, including public demonstrations and pre-university classrooms.  more » « less

    Prairie ecosystems, once expansive across North America, have faced significant degradation and fragmentation due to expanding agricultural development (World Wildlife Fund, 2023). Efforts to survey and restore prairies offer a unique opportunity for applied learning in environmental education. This paper explores the potential of prairie survey and restoration projects to enhance students' applied learning experiences and develop practical skills in ecological research, biodiversity conservation, and sustainable land management. Drawing upon interdisciplinary perspectives from ecology, education, and community engagement, and utilizing flora survey of the John Rushin Teaching and Research Prairie at Missouri Western State University as a model for applied learning, this paper examines the educational benefits of prairie survey and restoration and provides recommendations for integrating these activities into formal and informal educational settings. By engaging students in hands-on activities, we aim to enhance understanding, foster environmental stewardship, and contribute to effective prairie restoration.

    I describe the design and implementation of a series of university MSc courses in Switzerland and in Italy on the topic of “Cosmic Structure Formation” whose goal has been to provide to the students a formative experience using interwoven research practice and fundamental scientific content. The course educational framework, which is based on the ISEE Inquiry Framework, emphasizes science, as much in teaching as in research, as a set of practices, re-discovering and actualizing in modern terms the original pivotal role which these practices had in education in ancient times. In particular, the courses focus on formative, intuitive, student-centered and dialogic learning in opposition to the informative, mnemonic, teacher-centered and monologic teaching of frontal lecture-based instruction, which is still the dominant teaching framework in university education, at least in Europe. I describe how course activities are designed in such a way as to mirror authentic research, including all aspects which are usually not practiced in lecture-based courses and “standard” laboratories (e.g., generating and refining questions; making and testing assumptions; developing one’s own research path; and sharing, explaining and justifying ideas and results with peers). Finally, I discuss the major outcomes of the courses and the main challenges which were faced in order to provide to the students a truly transformative experience which could allow them to improve both as learners and future scientific researchers, as well as members of a larger community.

  3. (, Perspectives on undergraduate research and mentoring)
    Engaging students in teaching and learning science, technology, engineering, and math (STEM) is critically important in an era of social and economic change (such as the graying workforce in the US) and an increased need for skilled workers, which has led to a “radical opening” to work collectively to engage students and help them grow into leaders (Myers & Berkowicz, 2015, p. 7). As Hall et al. (2020) noted, high-quality mentoring that focuses on clear expectations, building a sense of community, one-to-one mentoring, and acquisition of mentoring skills can result in a salient experience for both the students and faculty involved. As a collaborative team spanning both the STEM sciences and educational teaching and leadership domains, we share experiences of navigating a pandemic, creating new pathways for collaboration, and seeking to engage students at both the university undergraduate as well as K-8 levels. In this article, we provide insights on both the design of the collaborative effort as well as how we benefited from the “radical opening” that presented itself in the form of a funded National Science Foundation (NSF) Research Experiences for Undergraduates (REU) grant called “An interdisciplinary approach to the marine sciences for first-year students”. Our project and related findings are particularly relevant to both the STEM and the educational fields because they offer a pathway to better engaging learners – and their supporting faculty – at both the university and school settings. We offer multiple perspectives and strategies across institutions and disciplines in the context of historical change and challenge.

    Our central hypothesis is that an inter-institution approach to educational transformation, centered on democratizing innovation across institutional boundaries, will effectively prepare next-generation innovators and engineers to address systemic and institutional racism and whiteness within STEM by challenging educational norms in higher education. This project is focused on co-facilitation and co-learning across Tuskegee University and the University of Colorado Boulder through an informal (outside of the classroom) undergraduate project, with land provided by Harvest Dreams. Undergraduate students from both institutions are a part of a collaborative cohort facilitated by faculty from both institutions to tackle each year's mission based on the faculty's expertise. This first year's cohort is focused on Creation as the inter-institutional group is creating the blueprint for the next four years with students and faculty heavily engaged with Harvest Dreams. Harvest Dreams has continued the legacy of teaching based on lessons from ancestors and has maintained land ownership since 1922. As a place pivotal to Black history in the United States, Harvest Dreams has played a pivotal part in forming such a project.

    Abstract Climate change and global urbanization have often been anticipated to increase future population exposure (frequency and intensity) to extreme weather over the coming decades. Here we examine how changes in urban land extent, population, and climate will respectively and collectively affect spatial patterns of future population exposures to climate extremes (including hot days, cold days, heavy rainfalls, and severe thunderstorm environments) across the continental U.S. at the end of the 21st century. Different from common impressions, we find that urban land patterns can sometimes reduce rather than increase population exposures to climate extremes, even heat extremes, and that spatial patterns instead of total quantities of urban land are more influential to population exposures. Our findings lead to preliminary suggestions for embedding long-term climate resilience in urban and regional land-use system designs, and strongly motivate searches for optimal spatial urban land patterns that can robustly moderate population exposures to climate extremes throughout the 21st century.
