In this paper, we present a successful, systemic, and sustainable approach to integrating technology into the K-12 teaching and learning environment. We will discuss obstacles and causes for failure that impeded previous attempts. We will share the vision, methodology and results that have had such a significant impact in New York City classrooms. Teachers have improved their content knowledge, technology and information literacy skills, perceptions about technology, and the use of inquiry to promote understanding. Students are better prepared to access and manage print and electronic information, think critically, solve problems, work on teams, and communicate and collaborate with students around the world.
