Teaching is supposed to be a professional activity requiring long and complicated training as well as official certification. The act of teaching is looked upon as a flow of knowledge from a higher source to an empty container.The student's role is one of receiving information; the teacher's role is one of sending it.
There is a clear distinction assumed between one who is supposed to know and another , usually younger person who is supposed not to know . However , teaching need not be the province of a special group of people nor need it be looked upon as a technical skill. Teaching can be more like guiding and assisting than forcing information into a supposedly empty head. If you have a certain skill you should be able to share it with someone . You do not have to get certified to convey what you know to someone else or to help them in their attempt to teach themselves. All of us , from the very youngest children to the oldest members of our culture should come to realize our own potential as teachers . We can share what we know, however little it might be , with someone who has need of that knowledge or skill.
