<P> In 1975, Apple Inc. began donating Apple 1 model computers to schools, and mainframes began to lose their former dominance over academic research . Computer usage continued to grow rapidly throughout this era . In 1977, it was estimated that over 90% of students at Dartmouth College had used computers at some point in their college careers .

It was during this period that drilling and practice programs were first developed for exclusive classroom use . Schools became divided over which computer manufacturers they were willing to support, with grade schools generally using Apple computers and high schools preferring DOS based machines . Hardware shortages in schools became a major issue, leaving many teachers unable to provide enough computers for students to use . Despite this, by 1989 computer usage shifted from being a relative rarity in American public schools, to being present in nearly every school district . </P> <P> The early 1990s marked the beginning of modern media technology such as CD - ROMs as well as the development of modern presentation software such as Microsoft PowerPoint .

This marked a significant increase in the demand for computer technology in many public school systems throughout the globe . </P> <P> Correlating with the development of modern operating systems like Windows 98 and the continuing support of government funding, the prevalence of educational computer usage boomed during this era . Between 1997 and 1999, the ratio of students to multimedia computers decreased from 21 students per machine to less than 10 students per machine . Colleges began creating specialized classrooms designed to provide students with access to the utilization of the most modern technology available . Classrooms such as the "Classroom 2000" built at Georgia Tech in 1999 which featured computers with audio and video equipment designed to capture detailed recordings of lectures as a replacement for traditional note taking began to become more common .
