This presentation will focus on how an introductory biology class was revised to accommodate the use of an Open Educational Resource (OER) from OpenStax College. Participants will have the opportunity to navigate the text used in the course for hands-on demonstrations of ease of use and exploration of features available to students. Data pertinent to student satisfaction, retention, and progression will be shared. The intended audience is anyone currently using or considering using OER. Discussion will focus on how use of an OER combined with various apps to facilitate flipping the classroom increased student engagement.
