Teaching and learning are the foundations of education. Teaching involves imparting knowledge from a more mature person to a less mature one through interaction, with the goal of inducing learning and causing changes in behavior. Learning is defined as acquiring new knowledge, skills, or behaviors through experience or instruction. Teaching and learning can be formal, such as in schools, or informal, like within families. Effective teaching follows principles like relating to learning, generating appropriate conditions, selecting strategies to achieve goals, and understanding the relationship between teaching and learning.
