Discrete Mathematics: An Open Introduction is a free, open source textbook appropriate for a first or second year undergraduate course for math majors, especially those who will go on to teach. The textbook has been developed while teaching the Discrete Mathematics course at the University of Northern Colorado. Primitive versions were used as the primary textbook for that course since Spring 2013, and have been used by other instructors as a free additional resource. Since then it has been used as the primary text for this course at UNC, as well as at other institutions.

Los modelos de datos son mecanismos que permiten la abstracción y representación de un dominio, mediante un conjunto de reglas y símbolos pertenecientes a un lenguaje de modelado que es conforme al modelo. Un modelo puede definirse como la abstracción que permite representar los diferentes elementos pertenecientes a un dominio del negocio, sus relaciones y asociaciones, conforme sucedería en el mundo real.

A modules-based approach to learning research skills that emphasizes the reflective nature of information discovery, the contextual basis for evaluating that information, and a recognition that information has value.

The ELC professional development model was designed to improve the quality of teacher candidates’ Practicum field placements and align teaching in field placements with Learning Standards used in the teacher education program.

Teams of four educators from varied settings worked in a Practicum placement setting for one semester to improve their teaching and align it with Learning Standards. An action research approach improved teaching challenges teams faced. Research articles were read to improve teams’ teaching challenges by implementing one agreed strategy. Teams video-recorded, assessed, and reflected on the impact of the strategy on their teaching, on teacher candidates’ learning and on children’s learning.

This text compiles six case studies from this model to illustrate how teaching challenges were improved. Appropriate for practiced educators as well as educators in training, this text provides a real world look into applying Learning Standards in early childhood classrooms.

This course material has been created for the course “Evaluation of comprehension and oral and written production in English” (LCL 462) from the English Language Teaching (ELT) program at the Institute of Literature and Language Sciences, Pontificia Universidad Católica de Valparaíso (PUCV). This course is located in the 8th semester of the curriculum of the bachelor degree of “Pedagogy in English” (English Language Initial Teacher Training) at PUCV. This course corresponds to the area of specific disciplinary training, complements the professional training course “Evaluation of Learning” of the School of Pedagogy and precedes the professional practice, academic-professional activity culminating in the curriculum of this career.

This textbook, Economics: Theory Through Applications, centers around student needs and expectations through two premises: … Students are motivated to study economics if they see that it relates to their own lives. … Students learn best from an inductive approach, in which they are first confronted with a problem, and then led through the process of solving that problem.

Many books claim to present economics in a way that is digestible for students; Russell and Andrew have truly created one from scratch. This textbook will assist you in increasing students’ economic literacy both by developing their aptitude for economic thinking and by presenting key insights about economics that every educated individual should know.

The Economics of Food and Agricultural Markets is written for applied intermediate microeconomics courses. The book showcases the power of economic principles to explain and predict issues and current events in the food, agricultural, agribusiness, international trade, and natural resource sectors. The field of agricultural economics is relevant, important and interesting. The study of market structures, also called industrial organization, provides powerful, timely, and useful tools for any individual or group making personal choices, business decisions, or public policies in food and agriculture industries.

The text focuses throughout on evidence on the economy, from around the world, and from history. It is motivated by questions—how can we explain what we see? The method is to ask interesting questions first and then to introduce models that help to answer them. Standard tools such as constrained optimization are taught by showing how they give insight into real-world problems. Economics as a discipline is set in a social, political, and ethical context in which institutions matter.

This books lays the foundation for prospective teachers to learn about various teaching methodologies and covers material typically found in many teacher training programs. Chapters in the text can be assigned either from beginning to end, as with a conventional printed book, or they can be selected in some other sequence to meet the needs of particular students or classes. In general the first half of the book focuses on broader questions and principles taken from psychology per se, and the second half focuses on somewhat more practical issues of teaching. But the division between “theory” and “practice” is only approximate; all parts of the book draw on research, theory, and practical wisdom wherever appropriate. Chapter 2 is about learning theory, and Chapter 3 is about development; but as we point out, these topics overlap with each other as well as with the concerns of daily teaching. Chapter 4 is about several forms of student diversity (what might be called individual differences in another context), and Chapter 5 is about one form of diversity that has become prominent in schools recently—students with disabilities. Chapter 6 is about motivation, a topic that is heavily studied by psychological researchers, but that also poses perennial challenges to classroom teachers.

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 book contains eight chapters. Chapter Two briefly describes the technology that makes electronic commerce possible, while Chapter Three introduces the topic of Web strategy. The major functions of marketing are described in the next five chapters: Promotion (Chapter Four); Promotion and Purchase (Chapter Five); Distribution (Chapter Six); Service (Chapter Seven); and Pricing (Chapter Eight). The final chapter takes a broader, societal perspective and discusses the influence of electronic commerce on society.

This book is not intended for budding mathematicians. It was created for a math program in which most of the students in upper-level math classes are planning to become secondary school teachers. For such students, conventional abstract algebra texts are practically incomprehensible, both in style and in content. Faced with this situation, we decided to create a book that our students could actually read for themselves. In this way we have been able to dedicate class time to problem-solving and personal interaction rather than rehashing the same material in lecture format.

Elementary Algebra is designed to meet the scope and sequence requirements of a one-semester elementary algebra course. The book’s organization makes it easy to adapt to a variety of course syllabi. The text expands on the fundamental concepts of algebra while addressing the needs of students with diverse backgrounds and learning styles. Each topic builds upon previously developed material to demonstrate the cohesiveness and structure of mathematics.

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 algebra and intermediate algebra. This textbook, Elementary Algebra, is the first part, written in a clear and concise manner, making no assumption of prior algebra experience. It carefully guides students from the basics to the more advanced techniques required to be successful in the next course.
