Those who can't

"Have you ever heard the phrase "those who can, do; those who can’t, teach", or its variation, "those who can’t do, teach"? Or, better yet, have you heard this one, "that’s not how we do it in the real world. The book is not right."? If you have never heard these phrases, then I am sure that at some point in your career, you will. These are the words of the “experienced employee”. The non-student type who found no significance in their college courses, i.e. the “hands-on” type that knows all. These phrases have often sparked other conversations. Conversations that actually question the need for degrees, or any form of continuing education."

The above is culled from an article written by Everett Lockhart in 2007 Career Insight article [click article to read the complete post]. This was sparked by a google search I made regarding the quote by George Bernard Shaw: "Those who can, do. Those who cannot, teach." Which is a bit derogatory to those in the teaching profession. Another is by reader: Shelley J. : "Those who cannot do either, manage the people who can."

A more positive and better quote would be:

"Those that know, do. Those that understand, teach." Aristotle Circa 322 BC

Regardless of the sensibilities of both teachers and managers, the first two quotes seem to suggest that "hands on" experience/knowledge is better or superior to theoretical knowledge. That by "doing", one presupposes a greater deal of understanding and a true application of theoretical knowledge.

In a way it is true, but not all knowledge can be acquired thru experience or by doing. It is better to learn from the experiences, research and studies of others to build on one's knowledge or understanding of things. There are of course skills and knowldge best learnt by doing, as most trade skills; hence apprenticeships and trade schools.

Obviously the test of one's learning and knowledge is by practical application of said knowledge. The learning process starts with theoretical building blocks, taught by rote since everyone presupposes that they are "basics" to one's discipline. The more challenge is to make sure the student continue on building and practicing the theoretical aspect to confirm that what he learnt in school is true to form in the real world. The best teachers are those with both theoretical knowledge as well as real life experience of what they are teaching. The role of a teacher is to motivate and plant the seed of seeking further knowledge, provide the foundation for the student and to make sure the student knows where and how to get the information required.
