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 therefore not capable of being wrong) 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 cultures 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. Select the statement that best expresses the main idea of the paragraph.
