OpenStax
OpenStax provides online textbooks for college and high school students. Rice University founded this non-profit digital learning platform and publisher of free textbooks in 2011, and it is well-liked by many students. It provides a variety of peer-reviewed texts from the leading colleges in the United States.
OpenStax offers free, outstanding, openly licensed textbooks for high school and college. Additionally, students can access an interactive algebra curriculum powered by machine learning, an educational research platform focused on improving teaching strategies and comprehending how students learn, and more.
Math (e.g., Algebra, Calculus, Statistics), Science (e.g., Physics, Chemistry, Biology), Social Sciences (e.g., Sociology, American Government), Humanities (e.g., History), Business, and many other subjects are covered. In the near future, the effort intends to offer textbooks on data sciences, nursing, and liberal arts.
OpenStax digital textbooks are available in PDF and ePub formats, as well as online reading. There are two ways to sign up: as a student or as an instructor. In the latter instance, you can have access to other materials (all books contain references to additional resources) that you can utilize in class.
Verified instructors, for example, can access answer guides and PowerPoint slides with photos from the book. The portal also includes OpenStax Tutor, a homework helper for students who require extra assistance. It also allows them to order print copies of their books.
OpenStax is an educational program whose objective is to "improve educational access and learning for everyone," which they appear to be doing very well so far. The so-called "textbook bubble" appears to be deflating gradually as a result of the activities of OpenStax and other projects that provide good disruption to the textbook industry.
