4 Notes
1. One-Minute Papers
Points
Agile views framework and
theory/practice link
Questions
Do some previews fit into
different info spaces more or less effectively?
How much info do people
really need? The more the better? [no!]
2. Case #1 BLS and Fedstats designs
3. Quick summaries of
readings and resources
my take on interfaces for
information seeking (handout)
Hearst’s lit review and our ARIST chapter---note the
thematic scheme
Greene et al and preview/overview examples
Carroll & Rosson
Production bias (aka
cognitive inertia)
Assimilation bias (force new info
into old templates)
“Designers of reference and
help systems count on users to recognize opportunities for new methods and to
search out the information needed to implement them.” P82 [“but users often figure out how to
use what they know to achieve new goals’]
the local
experts [p85] are called ‘gardeners’ by Nardi
approaches
to the production paradox
attack
end-product goal
reduce
motivation for learning (low cog load)
[reversibility, progressive disclosure, =training wheels]
design
better systems---give people what they want [task-oriented—e.g., our scenarios
in govstat project; advice-giving/reference
interview]
approaches
to the assimilation paradox
attack
assimilation [focus on system, not metaphor]
mitigate effects of
assimilation [direct manipulation—visual metaphors, reversible, notes negative
possible effects—too easy, less time on task, active processing]
design
for assimilation [capitalize on assimilation, metaphors but also
counterexamples; create mappings between conceptual action and physical
action—my rep & mech framework handout]
“Adults resist explicitly
addressing themselves to new learning.” P 101
