The Remixing Open Textbooks through an Equity Lens (ROTEL) project promotes textbook affordability, student success, and inclusion and equity to benefit all students, particularly those from minoritized populations. To date 22 books have been published. The assessment coordinators for the ROTEL project, will share the results of three semesters of data collection investigating the impact of using an intentionally designed inclusive textbook on student success and feelings of representation and belonging. They will share data that compares grade outcomes and course completions for students enrolled in course sections that used a ROTEL textbook versus those students enrolled in sections that did not use a ROTEL book. They will also share survey results on students’ perceptions and experiences using these textbooks.
