Why use teaching aids?
Teaching aids are useful to:
 reinforce what you are saying,
 ensure that your point is understood,
 signal what is important/essential,
 enable students to visualise or experience something
that is impractical to see or do in real life,
 engage students’ other senses in the learning process,
 facilitate different learning styles.
