CS6398 : Class notes (March 28, '96)
Quotable Quotes
- "Learning is assimilation, augmentation, and reorganization of
the incomplete mental structures held by the learners..." [Learner
Centered Design Theory paper from CHI'96]
- [In the Socioculturalism context] "Learning is enculturation" [Learner
Centered Design Theory paper from CHI'96]
- "Of course, one goal should still be to use that
increased zorch to make computers even easier to use..." [Soloway, Guzdial, and Hay paper from Interactions]
Discussions
Several questions arose during the discussion of the first quote for
the day. Mark elaborated on the phrase "assimilation and accomodation"
(which is also part of the cognitive science definition of
"constructivism"), giving the following definitions:
- Assimilation
- Involves bringing in knowledge, and connecting to the learner's
existing world model. This requires no reorganization of the
existing model.
- Accomodation
- This involves bringing in new knowledge that doesn't fit into
the learner's existing knowledge and structures, and thus requires
reorganization of the learner's world model.
An isssue that was raised was one about the long-term goals of
teaching children, namely "are we trying to make scientists of
children or are we trying to get functional children who know
science". Two research groups at opposite ends of the spectrum on
this issue were mentioned: John "Children are not short scientists"
Richards [head of the Educational
Technologies Dept. at BBN], and Marlene Scandamalia & Carl
Bereiter (both are at OISE, and
were part of the team that built CSILE.
Another topic of discussion involved the use of, and the theory behind
Emile and
the Explorer series (anyone have a link for this?). The Explorer
packages only allowed learner's to inspect and criticise an existing
model -- the actual workings of the model were hidden from the
learner. In contrast, Emile requires a learner to create/build his own
models. Thus, while a learner understands the fundamentals of a world
model in Emile (since it has been constructed by the learner), it also
involves a higher level of complexity than the Explorer series.
There was also a discussion (intermingled with a lot of the other
discussions) on techniques to be used on planners v/s bricoleurs. The
concept of "bricolage" was used by Turkle and Papert in their paper
"Epistemological Pluralism and the Revaluation of the Concrete."
