panOpen is a platform that enables mainstream institutional adoption of Open Educational Resources as an alternative to commercial textbooks. It provides faculty with turnkey peer-reviewed content, tools for customization, assessment, and analytics, and a means of financially sustaining campus-based OER efforts, allowing faculty to lower costs and improve learning outcomes. Mission: panOpen's platform is built on four value pillars: - Improving Affordability: OER is a better alternative to traditional textbook model and is a key part of creating an affordable learning experience for all students. - Commitment to Quality: Our libraries include only high-quality, peer-reviewed, openly licensed online educational materials. - Creation of Intuitive Tools: We make remixing, editing, and customization easy and offer concierge-style consultative services for those who need more assistance. The platform also makes it easy to add existing course content or create new content, such as quizzes. - Enabling Sustainability: Establishing a revenue sharing model that ensures that all relevant stakeholders (copyright holders, authors, faculty and institutions) are financially compensated for the time and effort spent creating, curating, adopting, and customizing OER content.
