Ausubel’s Expository Learning

Ausubel's theory is concerned with how individuals learn large amounts of
meaningful material from verbal/textual presentations in a school setting.
A major instructional mechanism proposed by Ausubel is the use of advance
organizers: "These organizers are introduced in advance of learning itself, and are
different from overviews and summaries which simply emphasize key ideas. In
order to enhance meaningful learning Ausubel believed that it was important to
have students preview information to be learned. Teachers could do this by
providing a brief introduction about the way that information that is going to be
presented is structured. An example of this might beopening a lesson with a
statement that provides an overview of what will be taught. In presenting outlines of
information, teachers can help students see the big picture to be learned.

Principles of Expository Learning

1. The most general ideas of a subject should be presented first and then progressively differentiated in terms of detail and specificity.

2. Instructional materials should attempt to integrate new material with previously presented information.
