    Defining Outcomes

    • 1963 AECT: "the design and use of messages which control the learning process" (p. 38)..."These steps include:

    -development,
    -utilization,
    -management and evaluation of processes and resources for learning (p.1)."
  • Period: to

    Textbook Ready

    AECT: definition "a focus on systematic processes and the use of technological resources are integral parts of the field. p. 5" Reference for this timeline is Trends and Issues in IDT, Reiser and Dempsey
