Download or read book Equity Culture and Place in Teaching Paleontology written by Christy C. Visaggi and published by Cambridge University Press. This book was released on 2020-08-20 with total page 71 pages. Available in PDF, EPUB and Kindle. Book excerpt: The diversity crisis in paleontology refers not to modern biota or the fossil record, but rather how our discipline lacks significant representation of individuals varying in race, ethnicity, and other aspects of identity. This Element is a call to action for broadening participation through improved classroom approaches as described in four sections. First, a brief review of the crisis and key concepts are presented. Next, culturally responsive pedagogy and related practices are introduced. Third, specific applications are offered for drawing cultural connections to studying the fossil record. Finally, recommendations including self-reflection are provided for fostering your own cultural competency. Our discipline offers much for understanding earth history and contributing new knowledge to a world impacted by humans. However, we must first more effectively welcome, support, and inspire all students to embrace meaning and value in paleontology; it is critical for securing the future of our field.

Download or read book Explorers of Deep Time written by Roy Plotnick and published by Columbia University Press. This book was released on 2022-01-04 with total page 483 pages. Available in PDF, EPUB and Kindle. Book excerpt: Paleontology is one of the most visible yet most misunderstood fields of science. Children dream of becoming paleontologists when they grow up. Museum visitors flock to exhibits on dinosaurs and other prehistoric animals. The media reports on fossil discoveries and new clues to mass extinctions. Nonetheless, misconceptions abound: paleontologists are assumed only to be interested in dinosaurs, and they are all too often imagined as bearded white men in battered cowboy hats. Roy Plotnick provides a behind-the-scenes look at paleontology as it exists today in all its complexity. He explores the field’s aims, methods, and possibilities, with an emphasis on the compelling personal stories of the scientists who have made it a career. Paleontologists study the entire history of life on Earth; they do not only use hammers and chisels to unearth fossils but are just as likely to work with cutting-edge computing technology. Plotnick presents the big questions about life’s history that drive paleontological research and shows why knowledge of Earth’s past is essential to understanding present-day environmental crises. He introduces readers to the diverse group of people of all genders, races, and international backgrounds who make up the twenty-first-century paleontology community, foregrounding their perspectives and firsthand narratives. He also frankly discusses the many challenges that face the profession, with key takeaways for aspiring scientists. Candid and comprehensive, Explorers of Deep Time is essential reading for anyone curious about the everyday work of real-life paleontologists.

Download or read book Flipping the Paleontology Classroom written by Matthew E. Clapham and published by Cambridge University Press. This book was released on 2018-11-15 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lecturing has been a staple of university pedagogy, but a shift is ongoing because of evidence that active engagement with content helps strengthen learning and build more advanced skills. The flipped classroom, which delivers content to students outside of the class meeting, is one approach to maximize time for active learning. The fundamental benefit of a flipped class is that students learn more, but ensuring student preparation and engagement can be challenging. Evaluation policies can provide incentives to guide student effort. Flipping a class requires an initial time commitment, but the workload associated with evaluating student work during the course can be mitigated. The personal interactions from active learning are extremely rewarding for students and instructors, especially when class sizes are small and suitable room layouts are available. Overall, flipping a course doesn't require special training, just a willingness to experiment, reflect, and adjust.

Download or read book Phylogenetic Comparative Methods A User s Guide for Paleontologists written by Laura C. Soul and published by Cambridge University Press. This book was released on 2021-05-27 with total page 77 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent advances in statistical approaches called phylogenetic comparative methods (PCMs) have provided paleontologists with a powerful set of analytical tools for investigating evolutionary tempo and mode in fossil lineages. However, attempts to integrate PCMs with fossil data often present workers with practical challenges or unfamiliar literature. This Element presents guides to the theory behind and the application of PCMs with fossil taxa. Based on an empirical dataset of Paleozoic crinoids, example analyses are presented to illustrate common applications of PCMs to fossil data, including investigating patterns of correlated trait evolution and macroevolutionary models of morphological change. The authors emphasize the importance of accounting for sources of uncertainty and discuss how to evaluate model fit and adequacy. Finally, the authors discuss several promising methods for modeling heterogeneous evolutionary dynamics with fossil phylogenies. Integrating phylogeny-based approaches with the fossil record provides a rigorous, quantitative perspective on understanding key patterns in the history of life.

Download or read book Integrating Active Learning into Paleontology Classes written by Alison N. Olcott and published by Cambridge University Press. This book was released on 2018-11-15 with total page 55 pages. Available in PDF, EPUB and Kindle. Book excerpt: The educational benefits of replacing in-class lectures with hands-on activities are clear. Such active learning is a natural fit for paleontology, which can provide opportunities for examining fossils, analyzing data and writing. Additionally, there are a number of topics in the field that are exciting to geology majors and non-majors alike: very few can resist the lure of dinosaurs, huge meteor impacts, vicious Cretaceous sharks or a giant Pleistocene land mammal. However, it can seem difficult to introduce these techniques into a large general education class full of non-majors: paleontological specimens provide a natural starting point for hands-on classroom activities, but in a large class it is not always practical or possible to provide enough fossil material for all students. The Element introduces different types of active learning approaches, and then explains how they have been applied to a large introductory paleontology class for non-majors.

Download or read book Confronting Prior Conceptions in Paleontology Courses written by Margaret M. Yacobucci and published by Cambridge University Press. This book was released on 2018-11-15 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: People hold a variety of prior conceptions that impact their learning. Prior conceptions that include erroneous or incomplete understandings represent a significant barrier to durable learning, as they are often difficult to change. While researchers have documented students' prior conceptions in many areas of geoscience, little is known about prior conceptions involving paleontology. In this Element, data on student prior conceptions from two introductory undergraduate paleontology courses are presented. In addition to more general misunderstandings about the nature of science, many students hold incorrect ideas about methods of historical geology, Earth history, ancient life, and evolution. Of special note are student perceptions of the limits of paleontology as scientific inquiry. By intentionally eliciting students' prior conceptions and implementing the pedagogical strategies described in other Elements in this series, lecturers can shape instruction to challenge this negative view of paleontology and improve student learning.

This book was released on 2018-11-29 with total page 45 pages. Available in PDF, EPUB and Kindle. Book excerpt: New online resources are opening doors for education and outreach in the Earth sciences. One of the most innovative online earth science portals is Macrostrat and its mobile client Rockd - an interface that combines geolocated geological maps with stratigraphic information, lithological data, and crowd-sourced images and descriptions of outcrops. These tools provide a unique educational opportunity for students to interact with primary geological data, create connections between local outcrops and global patterns, and make new field observations. Rockd incorporates an aspect of social media to its platform, which creates a sense of community for users. This Element outlines these resources, gives instructions on how to use them, and provides examples of how to integrate these resources into a variety of paleontology and earth science courses.

Download or read book Beyond Hands On written by David W. Goldsmith and published by Cambridge University Press. This book was released on 2018-11-29 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hands-on learning in paleontology, and geology in general, is fairly common practice. Students regularly use rocks, fossils, and data in the classroom throughout their undergraduate career, but they typically do it sitting in a chair in a lab. Kinesthetic learning is a teaching model that requires students to be physically active while learning. Students may be involved in a physical activity during class or might be using their own bodies to model some important concept. This Element briefly discusses the theory behind kinesthetic learning and how it fits into a student-centered, active-learning classroom. It then describes in detail methods for incorporating it into student exercises on biostratigraphy, assessment of sampling completeness, and modeling evolutionary processes. Assessment data demonstrates that these exercises have led to significantly improved student learning outcomes tied to these concepts.

Download or read book Expanded Sampling Across Ontogeny in Deltasuchus motherali Neosuchia Crocodyliformes written by Stephanie K. Drumheller and published by Cambridge University Press. This book was released on 2021-06-03 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: New material attributable to Deltasuchus motherali, a neosuchian from the Cenomanian of Texas, provides sampling across much of the ontogeny of this species. Detailed descriptions provide information about the paleobiology of this species, particularly with regards to how growth and development affected diet. Overall snout shape became progressively wider and more robust with age, suggesting that dietary shifts from juvenile to adult were not only a matter of size change, but of functional performance as well. These newly described elements provide additional characters upon which to base more robust phylogenetic analyses. The authors provide a revised diagnosis of this species, describing the new material and discussing incidents of apparent ontogenetic variation across the sampled population. The results of the ensuing phylogenetic analyses both situate Deltasuchus within an endemic clade of Appalachian crocodyliforms, separate and diagnosable from goniopholidids and pholidosaurs, herein referred to as Paluxysuchidae. This title is also available as Open Access on Cambridge Core.

Download or read book Testing Character Evolution Models in Phylogenetic Paleobiology written by April Wright and published by Cambridge University Press. This book was released on 2021-08-26 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Macroevolutionary inference has historically been treated as a two-step process, involving the inference of a tree, and then inference of a macroevolutionary model using that tree. Newer models blend the two steps. These methods make more complete use of fossils than the previous generation of Bayesian phylogenetic models. They also involve many more parameters than prior models, including parameters about which empiricists may have little intuition. In this Element, we set forth a framework for fitting complex, hierarchical models. The authors ultimately fit and use a joint tree and diversification model to estimate a dated phylogeny of the Cincta (Echinodermata), a morphologically distinct group of Cambrian echinoderms that lack the fivefold radial symmetry characteristic of extant members of the phylum. Although the phylogeny of cinctans remains poorly supported in places, this Element shows how models of character change and diversification contribute to understanding patterns of phylogenetic relatedness and testing macroevolutionary hypotheses.

Download or read book The Taphonomy of Echinoids written by James H. Nebelsick and published by Cambridge University Press. This book was released on 2021-10-21 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of echinoid evolution, diversity, and ecology has always suffered from the fact that they are represented by taxa showing widely differing architectural designs of their multi-plated skeletons, inhabiting a large range of marine paleoenvironments, which result in highly varying taphonomic biases dictating their presence and recognition. This Element addresses the taphonomy of echinoids and includes: a general introduction to the morphological features of echinoids that play a role in their preservation; a review of processes which play an important role in the differential preservation of both regular and irregular echinoids including predation and transport; a summary of taphonomic pathways included in actualistic studies for recent sea urchins and then reconstructed for fossil taxa; and finally, a case study of the variation of echinoid taphonomy across a shelf gradient using the rich Miocene echinoid fauna of Sardinia.

Download or read book The Neotoma Paleoecology Database written by Simon James Goring and published by Cambridge University Press. This book was released on 2018-11-29 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: Paleoecological data from the Quaternary Period (2.6 million years ago to present) provides an opportunity for educational outreach for the earth and biological sciences. Paleoecology data repositories serve as technical hubs and focal points within their disciplinary communities and so are uniquely situated to help produce teaching modules and engagement resources. The Neotoma Paleoecology Database provides support to educators from primary schools to graduate students. In collaboration with pedagogical experts, the Neotoma Paleoecology Database team has developed teaching modules and model workflows. Early education is centered on discovery; higher-level educational tools focus on illustrating best practices for technical tasks. Collaborations among pedagogic experts, technical experts and data stewards, centered around data resources such as Neotoma, provide an important role within research communities, and an important service to society, supporting best practices, translating current research advances to interested audiences, and communicating the importance of individual research disciplines.

Download or read book Dinosaurs written by Darrin Pagnac and published by Cambridge University Press. This book was released on 2018-11-15 with total page 43 pages. Available in PDF, EPUB and Kindle. Book excerpt: University dinosaur courses provide an influential venue for developing aptitude beyond knowledge of terrestrial Mesozoic reptiles. Passion for dinosaurs, when properly directed, can trigger interest in science and be used to develop critical thinking skills. Examination of dinosaur paleontology can develop competence in information analysis, perception of flawed arguments, recognition of persuasion techniques, and application of disciplined thought processes. Three methods for developing critical thought are outlined in this Element. The first uses dinosaur paleontology to illustrate logical fallacies and flawed arguments. The second is a method for evaluating primary dinosaur literature by students of any major. The final example entails critique of dinosaur documentaries based on the appearance of dinosaurs and the disconnect between scientific fact and storytelling techniques. Students are owed more than dinosaur facts; lecturers should foster a set of skills that equips students with the tools necessary to be perceptive citizens and science advocates.

Download or read book New Directions for University Museums written by Brad King and published by Rowman & Littlefield. This book was released on 2023-12-06 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: New Directions for University Museums is intended to help university museum leaders to help them plan strategically in the context of the issues and needs of the 2020s by examining trends affecting them and directions in response to those forces. It will lay out a series of potential directions for university museums in the 21st century using examples from the field. Although university museums are similar to other museums in their topic areas (art, natural history, archaeology, etc.) they are a unique category that requires special consideration. Today university museums are grappling with new forces that are affecting their future: University museums still have a dual responsibility to campus and community, and they still try to mount exhibitions that are attractive to the communities in which they are embedded. But they are rethinking the nature of service to town and gown in response to larger trends around accessibility. It is no longer enough to try to attract visitors; these museums are becoming much more active and outgoing in their outreach to the broader public. They have unparalleled access to academic firepower, but university museum research is no longer the sole province of academics, intended for publication in scholarly journals. In the 2020s, research is being made much more relevant to existential problems of the world. For example, some are bridging the gap between academic research and teaching and the most pressing social issues of our time, such as climate change, the fight against racism and the interface between humans and technology. University museum research is no longer cloistered, and these institutions are finding ways to better leverage the new knowledge yielded by collections-based research for both the university’s and for public benefit. Student engagement and education is still important, but communication is no longer unidirectional (from faculty and museum staff to students). Now student input and co-curation is now invited as learning becomes a two-way street. Moreover, public science communication has become a much more important role for university museums. These are, in effect, the “new directions” to which the title refers. The main thesis of the book is therefore that university museums are becoming much more outward-facing. They are engaging with the public and with the world at large as never before. In effect, they matter more than ever. This is the overarching “new direction”. Within this general approach, there are a number of questions that the book addresses: What are the expectations of university museums in the 21st century from their key stakeholders – university administrations, faculties and students, and the communities in which they are embedded? How are those expectations changing and how are the museums evolving to meet them? How are university museums navigating the minefields of political polarization, “cancel culture” or heightened activism on campus and in society at large? What is the nature of the relationship between the university’s research and teaching mission and the university museum? What trends can we identify, and how can we help the university museum director navigate those trends? The university-donor relationship: what can we learn from a study of donor expectations and the dynamics of university-donor relationships in contemporary society? How is the relationship between the university museum and the broader external community changing? How is the university museum contributing to (or detracting from) the overall relationship between the university and the community? What role is the university museum playing in terms of public communication of research, especially public science communication? This book is for all those who work in, benefit from or are interested in university museums. In particular, it is hoped that the book will help university museum leaders who are embarking on strategic plans understand the common issues that are currently affecting their peers, and provide some context and guidance to those leaders as they chart their own paths for the future and to advance larger goals. For faculty, it will show how the museum can help improve undergraduate teaching and graduate student training via highlights and illustrations of new ways in which faculty departments are cooperating and partnering with their campus museums, and from a university administration point of view, how the museum can help the university achieve its bigger strategic goals (such as helping increase the percentage of successful faculty grant applications).

Download or read book Elements of Paleontology The Stratigraphic Paleobiology of Nonmarine Systems written by Holland, Steven and published by Cambridge University Press. This book was released on 2021-04-02 with total page 137 pages. Available in PDF, EPUB and Kindle. Book excerpt: The principles of stratigraphic paleobiology can be readily applied to the nonmarine fossil record. Consistent spatial and temporal patterns of accommodation and sedimentation in sedimentary basins are an important control on stratigraphic architecture. Temperature and precipitation covary with elevation, causing significant variation in community composition, and changes in base level cause elevation to undergo predictable changes. These principles lead to eight sets of hypotheses about the nonmarine fossil record. Three relate to long-term and cyclical patterns in the preservation of major fossil groups and their taphonomy, as well as the occurrence of fossil concentrations. The remaining hypotheses relate to the widespread occurrence of elevation-correlated gradients in community composition, long-term and cyclical trends in these communities, and the stratigraphic position of abrupt changes in community composition. Testing of these hypotheses makes the stratigraphic paleobiology of nonmarine systems a promising area of investigation.

Download or read book Computational Fluid Dynamics and its Applications in Echinoderm Palaeobiology written by Imran A. Rahman and published by Cambridge University Press. This book was released on 2020-11-19 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: Computational fluid dynamics (CFD), which involves using computers to simulate fluid flow, is emerging as a powerful approach for elucidating the palaeobiology of ancient organisms. Here, Imran A. Rahman describes its applications for studying fossil echinoderms. When properly configured, CFD simulations can be used to test functional hypotheses in extinct species, informing on aspects such as feeding and stability. They also show great promise for addressing ecological questions related to the interaction between organisms and their environment. CFD has the potential to become an important tool in echinoderm palaeobiology over the coming years.
