Learning is perceived mainly as a transmission of knowledge from
teachers to students through narration and flexible application of
various media by teachers
Emphasis is put on facts, concepts, rules, procedural skills and
learning of theories
Lessons mainly consist of narration and questioning by teachers
Information technology acts as teaching aids

3. Role of teachers and students
Expository Approach
Role of Teachers
Teachers act as presenters of knowledge and evaluators of learning
accomplishment of students
Role of students
students are the receivers of knowledge, whose role is relatively passive

4. Learning Process Expository Approach
1. Introduction
Teacher arouses the attention of the students by using various skills, and
introduces the theme of learning
2. Theme Teaching
Teacher explains the topic of study with the assistance of different teaching
apparatus to improve students’ understanding towards the content being
taught
3. Summary and Questioning
Brief summaries will usually be presented after every teaching section.
Teacher uses questioning throughout the lessons to test students’
understanding of the content taught and to enhance interaction of teachers and
students during lessons
4. Summarization
Finally, teacher summarizes the content taught in the lessons.

5. Information Technology Expository Approach
Application of
Information Technology Expository Approach
As an effective and attractive demonstrating tool
As an assisting teaching medium with integrated audio, video and
internet information presenting functions
As an assisting tool for teachers to assess and supervise learning
progress of students.
