"MIX" is an online publishing service and information exchange from the Educational Management Services Division of McGraw-Hill. Through computer conferencing and electronic mail, MIX provides access to a network of people across the country who are seeking ways to put computers to use to improve the quality of education. MIX is an information utility that quickly retrieves and stores facts and ideas compiled from a variety of sources--media and technology coordinators; science, business, math, and social studies teachers; educational associations; and McGraw-Hill itself. The information is available through computer conferences and electronic mail. A copy of the "Online Educator," the monthly newsletter provided with each MIX subscription, is included. (EW)
