Electromagnetics Volume 1 by Steven W. Ellingson is a 225-page, peer-reviewed open educational resource intended for electrical engineering students in the third year of a bachelor of science degree program. It is intended as a primary textbook for a one-semester first course in undergraduate engineering electromagnetics. The book employs the “transmission lines first” approach in which transmission lines are introduced using a lumped-element equivalent circuit model for a differential length of transmission line, leading to one-dimensional wage equations for voltage and current.

This textbook provides a compact introduction to using the R programming language for data analysis. While there are good, freely available resources for learning these skills, they are generally not optimized for use in the classroom. Most fail to include a range of exercises, expect a high level of prior programming or mathematical experience, or only cover a specific niche aspect of data science. Moreover, the vast majority of these free sources do not include permissive licenses that make it easy to re-mix them and adapt it to a specific course. This textbook address these concerns by providing chapters designed to be covered in a single class period, a wide variety of exercises, and a Creative Commons license that allows others to make and republish their notes according to the needs of a specific curriculum.

Exploring Computer Science is intended for those with no experience with computer science at all. Its focus is on developing algorithms and solving problems. Python is used as the programming language.

Fish, Fishing, and Conservation is a 389-page, peer-reviewed open textbook intended for undergraduate students who are exploring majors in Fish & Wildlife. It is also relevant to a general audience or for use in courses which explore social and ethical aspects of fish, fishing and conservation.

People, places, and approaches to fishing are as varied as the diverse fish fauna that exist on the planet. As conservation planners recognize the value of substantial engagement of stakeholders in decision making and ineffectiveness of rigid top-down management approaches, Fish, Fishing, and Conservation asserts that all peoples must play a role in conservation. Through case studies, engaging narrative and graphics, and exercises, the text explores major motivations for fishing and non-fishing related values, responsible fisheries practices, the rights of all people to decide how to manage and conserve fish, their habitats, and how they are utilized in the context of overfishing as a pressing global problem for which appropriate solutions are not easily found nor implemented. Introductory chapters examine fish, fishing, and why fish matter and examine the role of values in driving conservation initiatives. Fish and their unique sensory capabilities are described along with a review of recent studies to examine issues of pain, sentience, and learning in fishes living in a foreign, underwater world. The text incorporates these new findings in conservation and management leading readers to evaluate and adopt suitable approaches to ethical reasoning which consider the welfare needs of wild and cultured fishes. Later chapters focus on the role of gender in fishing, conservation organizations, recreational fishing, and a focus on specific fisheries that reveal the principles of conservation and management as they play out in major controversies. Additionally, the textbook contains audio recordings of professional profiles by Virginia Tech students. These are linked at the beginning of each end-of-chapter Professional Profile. Audio recordings are also available on Spotify: https://open.spotify.com/show/06SnqAigflPXUgGNIHZxAX?si=Sljj3q9NRyOcclbmEE3npA

The discipline of Biosystems Engineering emerged in the 1990s from the traditional strongholds of agricultural engineering and food engineering. Biosystems engineering integrates engineering science and design with applied biological, environmental, and agricultural sciences. Introduction to Biosystems Engineering is targeted at 1st and 2nd year university-level students with an interest in biosystems engineering but who are not yet familiar with the breadth and depth of the subject. It is designed as a coherent educational resource, also available for download as individual digital chapters. The book can be used as a localized, customizable text for introductory courses in Biosystems Engineering globally. It is written as a series of stand-alone chapters organized under six major topics: Food and Bioprocessing; Environment; Buildings and Infrastructure; Information and Communications Technology and Data; Machinery Systems; and Energy. Each chapter is organized around stated learning outcomes and describes key concepts, applications of the concepts, and worked examples.

Introduction to Earth Science is a 530+ page open textbook designed to provide a comprehensive introduction to Earth Science that can be freely accessed online, read offline, printed, or purchased as a print-on-demand book. It is intended for a typical 1000-level university introductory course in the Geosciences, although its contents could be applied to many other related courses.

This text includes various important features designed to enhance the student learning experience in introductory Earth Science courses. These include a multitude of high-quality figures and images within each chapter that help to clarify key concepts and are optimized for viewing online. Self-test assessment questions are embedded in each online chapter that help students focus their learning. QR codes are provided for each assessment to allow students using print or PDF versions to easily access the quiz from an internet-capable device of their choice.

Adapted from openly-licensed works in geoscience, the sequence of the book differs from mainstream commercial texts in that it has been arranged to present elementary or foundational knowledge regarding rocks and minerals prior to discussion of more complex topics in Earth Science. Unlike prominent commercial texts for Earth Science, this book dedicates an individual chapter to each of the three major rock types, the processes of mass wasting, geological time, Earth history, and the origin of the universe and our solar system. Book content has been further customized to match the Pathways General Education Curriculum at Virginia Tech with a focus on Student Learning Outcomes (SLOs) for Pathways Concept 4, Reasoning in the Natural Sciences.

Introduction to Human Geography by Finlayson provides students with an accessible and concise introduction to the study of Human Geography. This text follows the approach of the successful open textbook World Regional Geography in offering students an engaging approach to geography informed by best practices in geography education. Introduction to Human Geography covers the key concepts and topics students need to succeed, providing commentary and reflection to help students deepen their understanding.

The general minimum prerequisite for understanding this book is the intellectual matur­ity of a junior-level (third-year) college student in an accredited four-year engineering curriculum. A mathematical second-order system is represented in this book primarily by a single second-order ODE, not in the state-space form by a pair of coupled first-order ODEs. Similarly, a two-degrees-of-freedom (fourth-order) system is represented by two coupled second-order ODEs, not in the state-space form by four coupled first-order ODEs. The book does not use bond graph modeling, the general and powerful, but complicated, modern tool for analysis of complex, multidisciplinary dynamic systems. The homework problems at the ends of chapters are very important to the learning objectives, so the author attempted to compose problems of practical interest and to make the problem statements as clear, correct, and unambiguous as possible. A major focus of the book is computer calculation of system characteristics and responses and graphical display of results, with use of basic (not advanced) MATLAB commands and programs. The book includes many examples and homework problems relevant to aerospace engineering, among which are rolling dynamics of flight vehicles, spacecraft actuators, aerospace motion sensors, and aeroelasticity. There are also several examples and homework problems illustrating and validating theory by using measured data to identify first- and second-order system dynamic characteristics based on mathematical models (e.g., time constants and natural frequencies), and system basic properties (e.g., mass, stiffness, and damping). Applications of real and simulated experimental data appear in many homework problems. The book contains somewhat more material than can be covered during a single standard college semester, so an instructor who wishes to use this as a one-semester course textbook should not attempt to cover the entire book, but instead should cover only those parts that are most relevant to the course objectives.
