"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. The WWC identified five studies of "Literacy Design Collaborative." Three of these studies meet WWC standards. The evidence presented in this report is from three studies of the effects of "Literacy Design Collaborative" on racially, ethnically, and geographically diverse student samples--in grades 4 through 8--in schools in Kentucky, New York City, and a school district on the West Coast. This intervention brief provides an overview of the full report. [For the full report, see ED611262. For the Intervention Snapshot, see ED611264.]
