Project Tomorrow is an invaluable partner for the National Science Digital Library (http://nsdl.org) - helping us in the past four years to understand patterns and trends in educational uses of technology, and to know and understand our users. This information is critical in helping us to not only tailor free resources for science and math education that are interesting and engaging. We incorporate findings from Speak Up! data into professional development opportunities that assist teachers and educators to effectively integrate and implement digital resources into their classroom teaching.
