Adapting or modifying educational resources is what gives open the competitive advantage over its commercial counterparts. Adapting an educational resource means that a faculty member can change the content to best suit the learning outcomes of their course; it means that students can take an active role in adapting and changing material for assignment and assessment purposes. However, adapting is rarely done across open educational projects. BCcampus's Open Textbook project is one of the few open projects to have successfully completed a series of adaptations on a number of open textbooks. This presentation will walk you through the steps of HOW to adapt an open textbook. Participants will be introduced to a step-by-step approach to adaptation, including technical format considerations and style guide supports. Participants will leave the session with an adaptation toolkit, produced by BCcampus, that is CC licensed and can be adapted for the needs of each institution or project.
