Climate Justice in Your Classroom
Alexandra Anderson-Frey; Brittany Johnson; Mikelle Nuwer; Luanne Thompson · University of Washington · 2023
As the inequitable impacts of climate change become more evident and destructive, it is essential for climate and environmental justice, as well as methods of civic engagement, to be taught at a high-level to college-level students. This book provides real examples of how professors at the University of Washington integrated these critical issues into their teachings, both in targeted lessons and as throughlines across an entire course. These samples of how environmental and climate justice have been successfully integrated into higher-level education can serve as both a record of the UW's progress towards centering JEDI at the heart of all students, and as a model for future instructors to use as they work to incorporate more aspects of justice and engagement into their own material.

Calculus in Context
James Callahan; David Cox; Kenneth Hoffman · Smith College Open Educational Resources: Textbooks · 1994
Designing the curriculum We believe that calculus can be for students what it was for Euler and the Bernoullis: a language and a tool for exploring the whole fabric of science. We also believe that much of the mathematical depth and vitality of calculus lies in connections to other sciences. The mathematical questions that arise are compelling in part because the answers matter to other disciplines. We began our work with a "clean slate," not by asking what parts of the traditional course to include or discard. Our starting points are thus our summary of what calculus is really about. Our curricular goals are what we aim to convey about the subject in the course. Our functional goals describe the attitudes and behaviors we hope our students will adopt in using calculus to approach scientific and mathematical questions. Starting Points Calculus is fundamentally a way of dealing with functional relationships that occur in scientific and mathematical contexts. The techniques of calculus must be subordinate to an overall view of the questions that give rise to these relationships. Technology radically enlarges the range of questions we can explore and the ways we can answer them. Computers and graphing calculators are much more than tools for teaching the traditional calculus. The concept of a dynamical system is central to science. Therefore, differential equations belong at the center of calculus, and technology makes this possible at the introductory level. The process of successive approximation is a key tool of calculus, even when the outcome of the process--the limit--cannot be explicitly given in closed form. Curricular Goals Develop calculus in the context of scientific and mathematical questions. Treat systems of differential equations as fundamental objects of study. Construct and analyze mathematical models. Use the method of successive approximations to define and solve problems. Develop geometric visualization with hand-drawn and computer graphics. Give num

Advanced Algebra
John Redden · 2012
Intermediate Algebra is the second part of a two-part course in Algebra. Written in a clear and concise manner, it carefully builds on the basics learned in Elementary Algebra and introduces the more advanced topics required for further study of applications found in most disciplines. Used as a standalone textbook, it offers plenty of review as well as something new to engage the student in each chapter. Written as a blend of the traditional and graphical approaches to the subject, this textbook introduces functions early and stresses the geometry behind the algebra. While CAS independent, a standard scientific calculator will be required and further research using technology is encouraged. Intermediate Algebra clearly lays out the steps required to build the skills needed to solve a variety of equations and interpret the results. With robust and diverse exercise sets, students have the opportunity to solve plenty of practice problems. In addition to embedded video examples and other online learning resources, the importance of practice with pencil and paper is stressed. This text respects the traditional approaches to algebra pedagogy while enhancing it with the technology available today. In addition, Intermediate Algebra was written from the ground up in an open and modular format, allowing the instructor to modify it and leverage their individual expertise as a means to maximize the student experience and success. The importance of Algebra cannot be overstated; it is the basis for all mathematical modeling used in all disciplines. After completing a course sequence based on Elementary and Intermediate Algebra, students will be on firm footing for success in higher-level studies at the college level.

Discrete Mathematics: An Open Introduction
Oscar Levin · Oscar Levin · 2024
Discrete Mathematics: An Open Introduction is a free, open source textbook appropriate for a first or second year undergraduate course for math and computer science majors. The book is especially well-suited for courses that incorporate inquiry-based learning. Since Spring 2013, the book has been used as the primary textbook or a supplemental resource at more than 200 colleges and universities around the world (see the partial adoptions list). After many years of development, I am pleased to announce that the 4th edition of Discrete Mathematics: an Open Introduction is now available, here and on Runestone Academy. The new edition brings many improvements and a new organization of content. In particular, the book now starts with logic and proofs, then practices those proofs with graph theory. The second half of the book contains material on counting (with a new "application to probability" section) and sequences. Over the last few years, I have found that students have more success with this arrangement. There is also a stronger emphasis on discrete structures, which should make the book more useful for students in computer science, while still focusing on understanding mathematical concepts essential for math majors and future math teachers.

Intermediate Algebra
John Redden · Saylor Foundation · 2012
It is essential to lay a solid foundation in mathematics if a student is to be competitive in today's global market. The importance of algebra, in particular, cannot be overstated, as it is the basis of all mathematical modeling used in applications found in all disciplines. Traditionally, the study of algebra is separated into a two parts, Elementary and Intermediate Algebra. This textbook by John Redden, Intermediate Algebra, is the second part. Written in a clear and concise manner, it carefully builds on the basics learned in Elementary Algebra and introduces the more advanced topics required for further study in applications found in most disciplines. Used as a standalone textbook, Intermediate Algebra offers plenty of review as well as something new to engage the student in each chapter. Written as a blend of the traditional and graphical approaches to the subject, this textbook introduces functions early and stresses the geometry behind the algebra. While CAS independent, a standard scientific calculator will be required and further research using technology is encouraged. Intermediate Algebra is written from the ground up in an open and modular format, allowing the instructor to modify it and leverage their individual expertise as a means to maximize the student experience and success. A more modernized element, embedded video examples, are present, but the importance of practice with pencil and paper is consistently stressed. Therefore, this text respects the traditional approaches to algebra pedagogy while enhancing it with the technology available today. The importance of Algebra cannot be overstated; it is the basis for all mathematical modeling used in all disciplines. After completing a course sequence based on Elementary and Intermediate Algebra, students will be on firm footing for success in higher-level studies at the college level.

Open Judicial Politics
Rorie Solberg; Jennifer Diascro; Eric Waltenburg · Oregon State University · 2020
The impetus for this volume was a multitude of conversations regarding pedagogy and teaching related to our judicial process courses. Based on these conversations, we identified four main threads or needs of our colleagues: First, many of us bring or want to bring more “political science” into our classes, though we also want to avoid the high costs of reinventing successful existing courses to do so. Second, our programs all require a political methodology course, and we want to reinforce those lessons in our substantive courses. We want to encourage our students’ understanding of how to read and understand research studies as well as how to craft their own research questions. Third, we want to keep our courses as current as possible. And fourth, we wanted to find a way to bring the cost of our courses down, as we see so many students struggle with the high costs of a college degree. This volume (as well as any future editions) addresses each of these concerns. Open Judicial Politics is a compilation of new and original research in judicial politics written specifically for the undergraduate audience, thus providing accessible examples of political science research that also address some of the more current concerns and controversies in our field. Additionally, every article is accompanied by some type of classroom activity—from basic discussion questions to full-blown simulations—that makes it easier for instructors to adapt the material to their courses and enhance classes with interactives. The chapters of the volume generally follow the well-worn path of most textbooks of judicial politics, making the volume an easy companion for adoption, and the material should fit seamlessly into the preestablished structures of most courses. Finally, the volume is an open-source resource, and adoption of the text adds no cost for our students. Whether one uses one or ten articles, the cost remains nil. This volume includes twenty-two original contributions that we have grou
