 Gordon Pask – adaptive teaching machines made us of computer technology.
 Richard Atkinson/Patrick Suppers – work in the 1960’s led to early

1960’s ~ Cognitive Revolution
 Robert Mayer published “Preparing Instructional Objectives” – the use

1980 – 1990’s ~ Computers for
Instructional Purposes

used at the secondary schools in the U.S.
 Existing associations of professionals were redefined: DAVI became AECT;
publication of Journal of instructional development
 However, computer impact is short-lived in the 90’s for instructional
purposes and were used instead for drill and practice
in the elementary setting & for work processing at
the secondary level (Reiser & Dempsey, 2012).
2000 – Present ~ Recent
 In 2008, more than 30% of training in business & industry
conducted via technology & 24% of that training was
delivered online.
