Things that make us smart A discussion about the ideas of Don Norman Larry G. Richards January 29, 2004
Who is Don Norman? • See www.jnd.org • Originally an electrical engineer • Then a psychologist • Now a cognitive scientist concerned with • Human factors / ergonomics • Usability • Human centered design
What is the central message of this book? • We have a “machine-centered orientation to life” • “We need to reverse the machine centered point of view and turn it into a person-centered point of view: Technology should serve us.”
Machine-centered versus • Human-centered Views of technology
Motto of the 1933 Chicago World’s Fair • Science finds • Industry applies • Man conforms
A person-centered motto for the twenty-first century • People propose • Science studies • Technology conforms
Technology can make us smart • How? • Give some examples.
Technology can make us smart • How? • By expanding our capabilities • Some examples: • Writing, reading, art, music • Logic, textbooks, encyclopedias • Science and engineering
Technology can make us stupid • Examples?
Cognitive artifacts • “Tools that aid the mind” • Physical artifacts • Paper, pencils, calculators, computers • Mental artifacts • Reading, arithmetic, logic, and language • Rules and structures • Procedures and routines
“...much of our human intelligence results from our ability to construct artifacts.” • “capable brains, ….limited in power”
“…new tools have moved us in unexpected ways to accept experience as a substitute for thought.” • page 15
Two kinds of cognition • Experiential • Reflective
Experiential cognition • “…we perceive and react to events around us, efficiently and effortlessly.” • The mode of expert behavior
Experiential cognition • The patterns of information are perceived and assimilated and the appropriate responses generated without apparent effort or delay. • Experiential thought is the essence of skilled behavior. It appears to flow naturally but years of experience or training may be required to make it possible.
Reflective cognition • Comparison and contrast • Thought • Decision making • “Reflection is greatly aided by systematic procedures and methods, and these are learned primarily by being taught.”
Reflective cognition • The reflective mode is that of concepts, of planning and reconsideration.
Three kinds of learning • Accretion • Tuning • Restructuring
Informal learning versus school learning • Characterize each
Multimedia • What is it? • Symbols (words, numbers) • Graphics (pictures, illustrations) • Sound (voice, music) • Animation (dynamic display, changing) • What can we do with multimedia that has educational value?
