The conventional wisdom in education is that any school reform--be it curriculum, instruction, assessment, or teacher professionalism--is most likely to take hold in schools that have strong leadership. The same holds true for technology. The most successful implementation of technology programs takes place in schools where the principal sees him or herself as a technology leader. This article lists the seven habits of highly effective technology-leading principals. Three highly effective technology leaders among the ranks of principals--Patrick Larkin (Burlington High School in Burlington, Massachusetts), Eric Sheninger (New Milford High School in New Milford, New Jersey) and Lyn Hilt (Brecknock Elementary School in Denver, Pennsylvania)--discuss how these habits have led to the successful implementation of educational technology in their schools.
