The overarching goal of this four-phase, in-service project--Girls Engaged in Mathematics and Science--was to change attitudes, behavior, pedagogy, and curriculum for girls through the provision of a vibrant, engaging, digital portal program with media that extends learning beyond the traditional classroom. Described here, Phases I and II were designed for work with mathematics and science teachers across a southern state to develop 250 lesson plans incorporating technology as well as hands-on activities that could be accessed by other teachers nationwide.
