This free online textbook (e-book in webspeak) is a one semester course in basic analysis. This book started its life as my lecture notes for Math 444 at the University of Illinois at Urbana-Champaign (UIUC) in the fall semester of 2009, and was later enhanced to teach Math 521 at University of Wisconsin-Madison (UW-Madison). A prerequisite for the course is a basic proof course. It should be possible to use the book for both a basic course for students who do not necessarily wish to go to graduate school, but also as a first semester of a more advanced course that also covers topics such as metric spaces.

Critical thinking is the ability to think clearly and rationally about what to do or what to believe. It includes the ability to engage in reflective and independent thinking. Someone with critical thinking skills is able to do the following:

Understand the logical connections between ideas.
Identify, construct, and evaluate arguments.
Detect inconsistencies and common mistakes in reasoning.
Solve problems systematically.
Identify the relevance and importance of ideas.
Reflect on the justification of one’s own beliefs and values.
Critical thinking is not simply a matter of accumulating information. A person with a good memory and who knows a lot of facts is not necessarily good at critical thinking. Critical thinkers are able to deduce consequences from what they know, make use of information to solve problems, and to seek relevant sources of information to inform themselves.

Critical thinking should not be confused with being argumentative or being critical of other people. Although critical thinking skills can be used in exposing fallacies and bad reasoning, critical thinking can also play an important role in cooperative reasoning and constructive tasks. Critical thinking can help us acquire knowledge, improve our theories, and strengthen arguments. We can also use critical thinking to enhance work processes and improve social institutions.

Some people believe that critical thinking hinders creativity because critical thinking requires following the rules of logic and rationality, whereas creativity might require breaking those rules. This is a misconception. Critical thinking is quite compatible with thinking “out-of-the-box,” challenging consensus views, and pursuing less popular approaches. If anything, critical thinking is an essential part of creativity because we need critical thinking to evaluate and improve our creative ideas.

This text provides a a graduate level introduction to the field of educational technology.

This book is aimed at managers, business owners, marketing managers, and aspiring social media marketing interns and managers. I will assume that however accomplished in your own field - baker, developer, teacher and that even as successful business owners, you approach the topic of social media marketing as a beginner. Even if you are an avid personal user of social networks, we will treat this book as a guided tour of social media for marketing purposes.

This book is a work in progress; and will hopefully remain that way in perpetuity; where authors will come back and update their chapters and others will add more chapter. It is aimed to serve as a textbook for classes exploring the nature of learning in the digital age. The genesis of this book is a desire to use OERs in all my teachings, coupled with the realization that the resources that I was looking for were not available and as such I needed to contribute in creating them. This book is a minor attempt to contribute to the vast repository of Open Educational Resources.

Philosophical Thought: across cultures and through the ages, is an open-educational resource (OER) to be used as a collection of readings for introductory philosophy courses. The objectives for developing and sharing this open resource are three-fold:

1. to provide a collection of philosophical works that can be used as a foundation for faculty and students to use in undergraduate philosophy courses
2. to provide a resource that is free to students
3. to provide a resource that compiles philosophical thought from a variety of cultures and eras

The works included in this book come from a wide range of sources. However, this book is indebted to Henry Imler’s editorial work on Sapienta and Phronesis, both of which are OER texts available on Pressbooks.

This modern, open-source guide to technical and professional writing explores workplace composition through theoretical and practical applications. Discussions of multiple writing genres will assist you in understanding how to apply for jobs, how to compose clear and precise business communications once the job has been acquired, and how to create documents -- such as proposals and reports -- that will be instrumental in helping to advance your career.

This resource is designed specifically to meet the academic writing needs of international students studying at universities in the United States. The materials in the book can be covered within a 14-week semester, but each chapter or section may also be used independently.Based on a series of needs analysis projects, this resource provides an overview of major rhetorical patterns of writing that are commonly used in university settings in the United States. These commonly required genres include descriptive and evaluative summaries, short essays, comparison and contrast assignments, literature reviews, descriptive reports, and proposals. The resource includes chapters that address the structure and purpose of these more common genres, including an awareness of the ways that the target audience and situation should shape the writing of each.

Who Teaches Writing is an open teaching and learning resource being used in English Composition classes at Oklahoma State University. It was authored by contributors from Oklahoma State University and also includes invited chapters from faculty and staff at institutions both inside and outside of Oklahoma. Contributors include faculty from various departments, contingent faculty and staff, and graduate instructors. One purpose of the resource is to provide short, relatively jargon-free chapters geared toward undergraduate students taking First-Year Composition. Support for this project was provided in part by OpenOKState and Oklahoma State University Libraries.

This resource focuses on the various processes involved in researching answers to various inquiry questions and building effective arguments within and outside academic contexts. The curriculum takes students through the processes of listening/summarizing, asking questions, characterizing scholarly debates, and entering those debates in order to meaningfully contribute to ongoing conversations.
