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.
