OpenStax Managing Director Daniel Williamson talks about the next steps in adopting open educational resources, outside of free textbooks.

On top of the publisher's already free catalog of textbooks, online homework resources are now free to teachers and students during the public health crisis.

Through a recent $30,000 grant, the school is joining a growing trend of students relying more heavily on digital resources.

The era of traditional textbooks and their high costs is coming to a close, says OpenStax' David Harris.

The Rice University-based OER publisher reported that students across 5,160 colleges and universities are saving a combined 77 million on its textbooks.

Commentary: As students and teachers seek to make education more affordable, they should consider a peer-review process for open educational resources.

In addition to spreading access to knowledge, the digital-focused education tools can help lower the cost of education for students, experts say.
