EMPIRICAL: Empirical was recently awarded a $200,000 grant from the Bill & Melinda Gates Foundation to develop a platform for web-based writing activities. The non-profit is the developer of Quill, a free, web-based tool that provides over 150 free, personalized, interactive writing and grammar activities for students in grades 3-12. The money will help Quill develop two new products: Stories With Friends, where students collaboratively write with chosen vocabulary words, and Proofing Ground, a peer review tool. Quill's platform was awarded a $25,000 grant from the Bill & Melinda Gates Foundation back in 2013.
