Digital Chalkboard (formally Brokers of Expertise or BoE) is an online community of California public school and district educators. California educators collaborate through group participation and discussions, upload educational classroom and administrative resources that help other educators access what works best in California schools and districts. As of the summer of 2014, over 70,000 educational resources have been contributed to the resource libraries. Both featured content providers from select non-profit organizations and approximately 19,000 California educators continue to contribute resources and collaborate. With the launch of the new site, over 300,000 additional digital resources have been added through a link to the national Learning Registry.
