"Literacy Design Collaborative" aims to help teachers improve their effectiveness in the classroom with a focus on supporting their literacy instruction. "Literacy Design Collaborative" provides professional development, coaching, and resources to support teachers to work collaboratively in their schools to create and use high-quality literacy instruction materials aimed at improving students' reading, research, and writing skills. Teachers across content areas--including English language arts, social studies, and science--can use the "Literacy Design Collaborative" program. This What Works Clearinghouse (WWC) report, part of the WWC's Teacher Excellence topic area, explores the effects of the "Literacy Design Collaborative" program on student achievement. This intervention snapshot provides findings on "Literacy Design Collaborative" from three studies that meet WWC standards. [For the full report, see ED611262.
