Environmental Science is a free and open textbook that enables students to develop a nuanced understanding of today’s most pressing environmental issues. This text helps students grasp the scientific foundation of environmental topics so they can better understand the world around them and their impact upon it. This text draws largely from open sources, in addition to new content from the editor.

This open online textbook on Environmental Toxicology aims at covering the field in its full width, including aspects of environmental chemistry, ecotoxicology, toxicology and risk assessment. With that, it will contribute to improving the quality, continuity and transparency of the education in environmental toxicology. We also want to make sure that fundamental insights on fate and effects of chemicals gained in the past are combined with recent approaches of effect assessment and molecular analysis of mechanisms causing toxicity.

Epidemiology is an openly licensed text designed for medical degree–seeking clinical students without a prior background in public health. Using sports medicine and injury prevention examples and applications, it aims to provide students with the basics of epidemiology terms and concepts and is intended to guide medical school students as they prepare for the USMLE Step 1 Exam and to transition from student to clinician. It includes an introduction to general concepts and terminology of epidemiology, study designs and their relationship to clinical questions, and the use of epidemiology in clinical diagnosis and screening of disease. Concluding sections of the book present sources of errors in epidemiologic studies, including bias, confounding, and effect modification. The book is notable for its use of accessible, inclusive figures and examples, and end-of-chapter study guides that summarize the chapter visually.

Applied economists frequently use equilibrium displacement models (EDMs), also termed linear elasticity models, for policy analyses because they can be used to estimate changes in prices and quantities that result from exogenous economic or policy shocks. These models are also widely used to estimate changes in producer and consumer surplus caused by exogenous economic shocks and to quantify the short- and long-term impacts of a variety of economic and regulatory actions across multiple markets. For the first time, a textbook that contains all of the theory and applications of EDMs along with a set of spreadsheet files is available in one place.

Short Description:
This training is designed for college instructors developing open curriculum projects with Open Oregon Educational Resources. It introduces course pilot instructors to four frameworks for equity-minded open course design, including Universal Design for Learning (UDL), Culturally Responsive Teaching (CRT), Transparency in Learning and Teaching (TILT), and Open Educational Practices (OEP). The training orients instructors to the use of course maps, module templates, student-centered assessment, H5P, open course packs, and design for continuous improvement.

This is a collection of the results of the Erasmus+ project GAMMA: GAMe-based learning in MAthematics.  In the GAMMA project, we have developed education materials for mathematics teachers who want to integrate GBL founded on digital technology effectively into their teaching practice. The materials could also be useful for teachers of other subjects who wish to integrate this method into their teaching. The authors are team members from GAMMA partner institutions.

Español sencillo: Elementary Spanish IThis is a full "textbook" for Introductory Spanish I (101), which constitutes an entire semester of college-level Spanish. The course could be used in a high school setting, though more materials/activites would likely be needed to fill out the additional class time. This work, especially the first few chapters, builds upon the OER Hola a Todos: Elementary Spanish I, by Elizabeth Combier and Mariana Stone. Their work is hosted by Galileo Open Learning Materials. This work was funded by a 2019 Open Education Resource Grant from the University of Pittsburgh. 

The intention of this book is to expand literacy skills of Spanish speaking students from their dominant English environment into Spanish.

t is increasingly clear that the shapes of reality – whether of the natural world, or of the built environment – are in some profound sense mathematical. Therefore it would benefit students and educated adults to understand what makes mathematics itself ‘tick’, and to appreciate why its shapes, patterns and formulae provide us with precisely the language we need to make sense of the world around us. The second part of this challenge may require some specialist experience, but the authors of this book concentrate on the first part, and explore the extent to which elementary mathematics allows us all to understand something of the nature of mathematics from the inside.

The Essence of Mathematics consists of a sequence of 270 problems – with commentary and full solutions. The reader is assumed to have a reasonable grasp of school mathematics. More importantly, s/he should want to understand something of mathematics beyond the classroom, and be willing to engage with (and to reflect upon) challenging problems that highlight the essence of the discipline.

The book consists of six chapters of increasing sophistication (Mental Skills; Arithmetic; Word Problems; Algebra; Geometry; Infinity), with interleaved commentary. The content will appeal to students considering further study of mathematics at university, teachers of mathematics at age 14-18, and anyone who wants to see what this kind of elementary content has to tell us about how mathematics really works.
