This report focuses on teaching with the World Wide Web. An introduction describes the Illinois State Board of Education's (ISBE's) efforts in urging local schools to integrate information technology into all aspects of their curriculum and in emphasizing the need for technology-focused staff development for Illinois teachers. ISBE supports Project Linc~On, a plan to install T1 lines and connect ports to every Illinois public school by the year 2000. Six anticipated benefits to Illinois schools from Project Linc~On are described, and other ISBE programs are listed that aim to improve schools' technological infrastructure, teacher skills, and long-range technology planning. Six essential standards for integrating information technology into classroom instruction are discussed, followed by a brief description of the World Wide Web and the educational potential of virtual learning communities. Eighty-four Web sites for K-12 educators are listed in 8 categories: general K-12 resources, state and federal education, science and mathematics resources, language arts resources, cultural and language resources, history and social science resources, museum sites on the Web, and schools on the Web.
