Teaching is the process by which a
person helps other people learn. It is one of our
most important activities. Teaching helps people
gain the knowledge and attitudes they need to
be responsible citizens, earn a living, and lead a useful, rewarding life. Teaching also
provides the chief means of passing knowledge on to the next generation. If there were no
teachers, people would have to learn everything by themselves. Few people could learn
enough on their own to get along in the world. The world itself would changes greatly as
mankind lost the knowledge, skills, and ideals inherited from past generations.
