Susana Velasco always thought she designed lessons for her kindergarten students to help them meet the academic standards for their grade. But now she feels better equipped to adapt instruction to meet the needs of all the children in her class--a skill she has developed through her school's participation in the Literacy Design Collaborative (LDC). LDC gives teachers templates and tools that support students in doing more challenging work aligned to the Common Core. But the process is also a growing experience for teachers as they work with colleagues to refine the lessons and tasks to ensure they are asking students the right questions. Learning more about how LDC impacts teachers' practice is one of the goals of a five-year, $12 million Investing in Innovation (i3) "validation" grant from the U.S. Department of Education. LDC is providing coaching, summer institutes, and online training to groups of teachers in 12 Los Angeles Unified School District schools, including Florence Avenue. Another 15 New York City schools are also participating this year, but the numbers of schools will expand substantially over the course of the grant.
