The power of LibreTexts and ADAPT has been transformative in my classroom and in OER development. These platforms have not only democratized access to quality educational resources but also fostered a collaborative and innovative spirit among educators. By eliminating the high costs associated with traditional textbooks and homework platforms, LibreTexts has enhanced the learning experience and empowered students to achieve their academic goals without the financial burden traditionally associated with higher education.

LibreTexts provides the key that unlocks the door to a world of possibilities for accessing, creating, and sharing educational resources that empower teachers and students to engage in authentic, meaningful learning and teaching opportunities. This inventive, innovative repository of open educational resources can help guide learners to success.
Just as the protagonists in "The Wizard of Oz" discover their own potential abilities and strengths without needing to rely on traditional means, so, too, LibreTexts can serve as a pathway, similar to "The Yellow Brick Road," to the discovery of skills, knowledge, and self-confidence." There's no place like LibreTexts for the exciting world of open education!

LibreTexts has made my transition to using OER textbooks in all my math courses easy and enjoyable! I love the way I can customize existing OER content so easily into a coherent textbook that covers exactly the right topics and in the way I want them presented. If an explanation or an instruction is unclear, I can improve the wording quickly and easily. If additional examples are needed for a topic, I can easily add them. My students appreciate not having to pay for a textbook, and their performance has not been hindered. In fact, on topics for which I have added my own new explanations and examples, they have performed even better than before!

I have moved to LibreTexts for all of my classes. It has allowed me to take full advantage of OER so that I was able to customize the textbook by remixing it and also directly embed my videos throughout and embed fully interactive activities allowing students to have mathematics learning materials that address all of their learning styles. My students have repeatedly thanked me for providing them with free materials that provide them the opportunity to succeed in their math classes.

I have been using the LibreTexts ADAPT homework system for several years, and it has been an invaluable tool for student learning. The well-designed question banks provide engaging practice opportunities that help students deepen their understanding of course material. ADAPT has become an integral part of my teaching strategy to support student success.

During the 4 years that I have used it, the growth and development of ADAPT has been remarkable. It is an indispensable part of my pedagogy to enhance student success and learning.

LibreTexts Founder and Executive Director, Delmar Larsen, provided an in-depth, hands-on workshop that covered everything our faculty needed to know to get started using ADAPT for their courses. We learned more about the open homework and assessment platform and how it can help take our campus OER efforts to the next level! We were excited by all the upcoming new features that will enhance the interactivity of OER for students and provide faculty with even more options for creating accessible, engaging content!

Delmar's recent live presentation on the LibreTexts ADAPT homework system at West Los Angeles College was both informative and timely. Several of our faculty members, including those from the Spanish and Biotechnology departments, showed great interest in the training. This training was particularly relevant as they are in the process of converting their Spanish and Biotechnology Lab Technician educational pathways to OER/ZTC. in addition, the discussion about the new AI tutoring tool that Delmar and his team are developing this summer for integration into the ADAPT system was especially fascinating!

Systems/Electronic Resources/OER Librarian, West Los Angeles College
LibreTexts has helped revolutionize Open Educational Resources on our campus. Our faculty have found community with other educators who are also freeing their courses, and they have embraced the academic freedom inherent in curating and creating their own materials. We couldn't have accomplished so much, so quickly, without their support.
