What matters about an educational activity is how learners respond to
it. This involves questions of ''authenticity'' (Widdowson, 1981) and
of meaning, especially ''meaning which is one's own'' (Prabhu, 1987).
If a learner responds as a pupil, not showing much personal interest,
I call this an exercise. If a learner responds in a creative way, with
spontaneity and independence, I call this a piece of work. Work autho
red by the learners themselves is authentic in a way that assignments
provided by a teacher or materials designer are unlikely to be. This i
s significant for notions of learner autonomy which is partly a matter
of learners having an opportunity to define their own meanings and de
velop them. Investigative research facilitates learners pursuing their
own interests and meanings, and releases them from the need to behave
as pupils. The change of status is emancipating and is a way of engag
ing learner autonomy.
