To
choose theoretical principles
|
|
 |
|
|
|
|
|
we rely on a
triangulation from
|
|
|
three
independent research disciplines.
|
|
|
|
Ecological
: observations of normal behavior,
|
|
|
 |
|
|
|
|
|
in educational
environments,
|
|
|
(mostly carried
out by educational researchers)
|
|
|
|
Psychological
: responses to simplified experiments
|
|
|
 |
|
|
|
|
|
designed to get
at fundamental cognitive structures,
|
|
(mostly carried
out by psychologists)
|
|
|
|
Neurological
: studies of the structure
|
|
|
 |
|
|
|
|
|
and functioning of the
brain,
|
|
|
(mostly carried
out by neuroscientists)
