Explanation : Authoritative discourse consists in monologic
communication. In the classroom, it happens
in the form of lectures, recitation, activities
and the completion of textbook or worksheet
activities. In these activities what comes to
count as knowledge is based on 'right' or
'wrong' answers.
Dialogic discourse comprises more conver-
sational communication. In the classroom,
this may involve comparison aod creation
of ideas. It is open to different perspectives
and seeks no fixed answers. It encourages
participants to acknowledge and understand
the perspective of others.
The teaching methods which have a great
scope for dialogic discourse are tutorials---
self-paced instructional program providing
step by step information on a concept or
learning unit; problem solving--- an ongoing
activity to discover what is not known; and,
group discussion- systematic exchange
of information, views and opinions about a
topic, problem, issue or situation among the
members of a group who share some common
objective.
