(this was in response to Cindy's horror stories)
Good point, Tad. We can't assume that one element in the learning
environment is the cause of anything in particular.
However, before people reject the validity of Cindy's point, let's
remember that ANY research on learning has the same flaw. There is
no such thing as a _perfect_ educational research design; the design
factors are not the only ones learners encounter.
Currently, there is quite a bit of noise about the research on
learning in classes that use graphing calculators. Some of these
show enhanced learning in the graphing calculator method; some show
equal learning; some show better student attitudes.
Other learning factors have gone through this process. We have had
such studies on computer assisted learning, mastery learning,
advanced organizers, tutoring, lecture vs non-lecture, and so on.
In most cases, the positive research results on a learning factor
did _not_ follow when the factor was "institutionalized" in a
larger quantity of classes. We tend to think analytically, where
the parts of a whole have meaning; the world (and especially learners)
tend to function in a more social/intuitive/holistic fashion.
Before we conclude that calculators/technology is good/bad for
learning, let's think about the whole picture: the learner,
the content, the methods, . . .
(If you are thinking that I could have said all this by saying
"there are no simple answers", you have the rough idea.)
