As technology companies introduce innovative products and services for the education market, school districts have the opportunity to invest in technologies designed to improve instruction and operations--from teaching, learning and assessments to organizational efficiency. Perhaps the greatest promise of anticipated technologies is their potential to transform schools through innovation. In this guide, the Emerging Technologies Committee (ETC) of the Consortium for School Networking (CoSN) will look at the most promising technologies in store for schools. The committee comprises volunteers from school districts, companies, not-for-profit organizations and institutions of higher education, to bring the perspectives of both education and industry to focus on the coming attractions in educational technology.
