Concept & Principle
Theory explains how some aspect of human behaviour or performance is organized. It thus enables us to make predictions about that behaviour.
The components of theory are concepts and principles
A concept is a symbolic representation of an actual thing
Eg - tree, computer, distance, etc.
A principle expresses the relationship between two or more concepts
Concepts and principles serve two important functions :
▸ They help us to understand or explain what is going on around us.
▸ They help us predict future events
