Evidence of impact: Transforming teacher education with preparing tomorrow's teachers to teach with technology (PT3) grants

This article uses the framework of technological pedagogical content knowledge (TPACK; Mishra & Koehler, 2006) to analyze findings across projects from the U.S. Department of Education's Preparing Tomorrow's Teachers to Use Technology (PT3) initiative. Approaches such as mentoring methods course faculty, teachers, and creating technology-rich instructional materials were associated with increases in preservice teachers' technological knowledge and their frequency of technology-rich instruction during field experiences. Lastly, the authors provide implications and directions for future analyses of technology integration efforts.
