Learning is a psychological process of acquiring new or modifying existing knowledge, behaviours, skills, values or preferences which leads to a change in behaviour of an individual. There are certain basic psychological factors and principles related to learning which every instructor should understand and be able to apply in his presentation. The learning does not take place unless the learner is ready and instructor is willing to teach.

This reasoning is known as principles of learning. For making the students to learn better, it is important for an instructor to know the principles of learning, which influence in better learning.
