About This Book

This textbook was created through Connecting the Pipeline: Libraries, OER, and Dual Enrollment from Secondary to Postsecondary, a $1.3 million project funded by LOUIS: The Louisiana Library Network and the Institute of Library and Museum Services. This project supports the extension of access to high-quality post-secondary opportunities to high school students across Louisiana and beyond by creating materials that can be adopted for dual enrollment environments. Dual enrollment is the opportunity for a student to be enrolled in high school and college at the same time.

The cohort-developed OER course materials are released under a license that permits their free use, reuse, modification, and sharing with others. This includes a corresponding course available in Moodle and Canvas that can be imported to other platforms. For access/questions, contact Affordable Learning Louisiana.

If you are adopting this textbook, we would be glad to know of your use via this brief survey.
