An educator can find many types of OER in many places online. For instance, BC Campus and the Open Textbook Library are full of free, CC-licensed textbooks. You can simply reuse what you find, revise, or mix it with your work to make it your own. Educators can use OER to encourage their students to study independently in a flexible environment. These free courses and learning opportunities give students the chance to explore what the school has to offer before they enroll. Thus, they get to experience the classroom, taste what the school has to offer, and be better prepared upon actually entering the classroom. There are other available resources besides textbooks and courses. Two others include slide decks and lectures. Educators no longer have to start from scratch when they want to create a lecture or a presentation. They can grab OER to supplement what they already have!
