Connected kids deserve connected schools — and Mark Zuckerberg is determined to make that access a reality.

The Facebook cofounder announced on Thursday that he and his wife, Priscilla Chan, will give $20 million to the nonprofit EducationSuperHighway, which helps bring high-speed Internet to public school systems.

"In schools, Internet is critical for enabling something we know leads to better results: personalized learning," Zuckerberg wrote in his Facebook post announcing the donation.

Many U.S. schools are connected to the Internet, but less than half have access to high-speed broadband, Zuckerberg wrote. And there's research to support that.

In addition to the lack of high-quality connection, Internet access that does exist in public schools isn't always available for student learning.

According to the National Center for Education Statistics, 93% of public school teachers have at least one computer available in the classroom with Internet access. Only about 70% of teachers, however, reported that they or their students used computers in the classroom during instructional time, meaning the personalized student learning Zuckerberg hopes to provide is still relatively rare.

In his announcement, Zuckerberg stresses that personalized learning software is essential to student success, describing this customized learning as giving students the material they are interested in at their own pace and in a style tailored to them.

"One day we'll connect the world and provide personalized learning for all students, and we'll keep focusing on this until that happens," Zuckerberg wrote.

Zuckerberg and Chan are no strangers to the idea of overhauling and rethinking how public education work. They already support several efforts to change and challenge the ways public schools go about instruction, including Summit Public Schools and AltSchool.

The duo is also starting their own educational endeavor, spearheaded by Chan, called The Primary School. The private, non-profit K-12 initiative will bring together education and quality, comprehensive youth and family health care for participants. It's set to open in August 2016.

Zuckerberg and Chan previously donated $3 million to EducationSuperHighway in 2013.
