Learning/Cognitive Sciences
A short list of driving forces that led to design's
emergence into today's educational scene could include:
(a) Intuitive, visionary teachers who saw the value
of these tasks to motivate students, give them meaningful
contexts for learning while solving complex "real
world" challenges.
(b) Research findings from the Learning and Cognitive
Sciences that pointed to their potential value. A useful
reference that summarizes these fields is the National
Research Council's How
People Learn, a must-have handbook for doing "informed
teaching" with design tasks.
This section of DITC presents findings from the Learning
and Cognitive Sciences that are relevant to design-based
learning. They amount to a compelling set of cases that
can come in handy in your day-to-day teaching:
- Case-Based
Reasoning
Georgia Tech's Janet Kolodner talks about an innovative
approach that she developed for machine learning based
on providing them cases or examples from to learn,
and how she then applied similar lessons to the LBD
curriculum she created.
- Problem
Finding/Solving
Solving problems has been well studied and involves
topic-specific strategies. Such tasks usually state
what needs to be solved: most have single correct
answers. Open-ended design tasks often do not tell
you what to solve or how -- the problem needs to be
found before it solved.
- Surface/Deep
Categories
Novice versus expert physicists categorized end-of-chapter
problems differently. Novices notice surface features
about problems, while the experts grouped them by
deeper features.
- Memorizing/Understanding
More complex performances, like design, require require
a flexible understanding of what is known to so that
it can be adapted to new situations. Five features
for developing students understanding are described
here.
- Near/Far
Transfer
Being able to take something learned and apply it
to a new situation is the hallmark of learning. How
similar the new situation is to the original setting
and task determines if the application of learning
involves "near transfer" or "far transfer".
- Short/Long-Term
Memory Some
of cognitive science's most enduring findings revolve
around limits of what we can keep in mind in the short-term,
and what we can remember and recall in the long-term.
Learn about the rule-of-thumb called the "magic
number 7, plus or minus 2" and other findings
regarding memory.
- Primacy/Recency
Effect The
first and last things learned are often the best remembered
items.
- Novice/Expert
Studies
One mainstay of early Cognitive Science work was its
study of expertises like chess and medical decision-making.
Comparisons of novice versus expert thinking and performance
were used to describe preferred outcomes for learners.
- Scaffolding
Giving support to enable people to perform accurately
and optimally.
- Elaboration
& Learning
One of the surprising, non-intuitive findings from
Cognitive Science is that just interacting mentally
with a topic, whether it makes sense or not, can lead
to improved connection-making and learning.
