Ancillary resources

Open textbook authors should consider adding ancillary resources to their textbook whenever possible. Traditional textbooks often provide instructors with ancillary resources like slides, test banks, image banks, and videos. A BC Faculty Survey on Open Educational Resources (2015) found that 12% of faculty wouldn’t adopt an open textbook that was not accompanied by ancillary resources, and 28% reported that they felt they didn’t have the time to experiment with open education resources in their classroom.

After putting so much work into your open textbook, adding features that will make it easier for instructors to integrate your book into their teaching will increase the likelihood that it will be adopted or adapted.

NOTE: Be sure to talk to email to discuss ways that we can help ensure ancillary materials are stored, shared and managed for long-term access.

Developing Ancillary Resources

One of the most important aspects of creating ancillary material is to make sure you publish the material using open-source or free software so anyone can use, reuse, and adapt the material without having to purchase proprietary software.

Also remember to include a Creative Commons license on the work to clearly communicate permitted uses to others.

Teaching Slides

Slides are one of the easiest and most important ancillary materials you can create to support instructors looking to adopt your textbook. Think about creating and publishing these slides using open-source or freely available software such as Google Slides or LibreOffice.

Test Banks

Including test banks and assessments with your textbook will make it that much more attractive to potential adopters. To ensure academic integrity, assessment material is typically provided to users only upon request. This can be done by placing the materials within a password protected site, or by requiring requests to be made by email.

If developing a test bank, email so we can work with you to facilitate secure access to these materials.

Creating Ancillary Resources with Development Sprints

If you have adopted an open textbook or are building one from scratch, consider using a development sprint to build ancillary resources. Development sprints allow a group of instructors to work together over a short period, usually one or two days, to develop open content.
