Research

• Multimedia computer applications promote
  information retention (Monti, Cicchetti,
  Goodkind, Ganci, 1994).

Using hypermedia, learners are permitted to
pursue a non-linear train of thought and make
meaningful knowledge connections (Kommers,
Grabinger, Dunlap, 1996).
In 1998, 70 of all jobs required basic
technology literacy. By 2010 it is predicted
that 100 of all jobs will require technology
and 80 of these jobs dont even exist yet (Noon,
1998)
