Just like you, many of your instructors have grown concerned with the rapidly rising costs of college textbooks 和 other learning resources. They recognize that switching to OER is a way of savings students money without sacrificing the quality of your education. And because OER are openly licensed, instructors also have a more freedom to customize OER for their courses. Undoubtedly you have had times w在这里 you have purchased a textbook only to be assigned select chapters or sections to read rather than the entire book. With OER, instructors can provide only those materials that are relevant to the class which means no more paying for books you aren't going to need. Plus, since OER are online, instructors can make sure the content of their OER is always up to date without having to wait for a publisher to release a new edition of a textbook.
The short answer is yes! Studies have been conducted that show many students 和 faculty believe OER to be just as accurate 和 useful as traditional learning materials. For a list of these studies you can visit the Open Education Group's website在这里.
By definition open educational resources are "born digital" which means they are created as online resources. One of the many benefits of OER is that they are online 和 can be accessed from any device with an Internet connection (desktop computer, cell phone, tablet, etc.). That said, t在这里 are ways to obtain print copies of OER for much lower cost than traditional textbooks. For example:
- You can print only the information you need from an OER using a printer at the library or tech mall for .15 a page (.75 for color copies).
- 像亚马逊和lulu.com按成本价提供印刷服务，这意味着没有出版商或书店加价。
- 一些OER项目，例如OpenStax和LibreTexts, offer ready made print files for OER that can be sent to sites such a lulu 和 printed at cost; again, these cost far less than buying a textbook from the bookstore or online from a publisher or vendor such as Amazon.
While library resources are always free for students to use, many of these resources, such as databases 和 journals, are paid for by the library. Since they are not freely available online, or openly licensed for remixing 和 revising, library resources are not considered OER. However, they are a great alternative to more expensive textbooks 和 learning materials when you are doing research for your courses!
The Grossmont大学 library also has a collection of textbooks on reserve that can be checked out for a limited time (usually 4 hours) 和 used instead of purchasing an expensive textbook for a course. While not every book for every class is available, stop by the library to see if yours is available during the first week of class 和 submit a purchase request with a librarian if it is not yet in the collection. They will always do their best to get copies of the most popular textbooks on reserve each semester.
