What makes a teacher great?
I guess we’ve all had our fair share of the good and the bad (and the ugly, I mean the really bad). Not sure about the school system these days, but in ‘the bad old days’ many teachers could be described as yes, bad. This includes plain bad, badass, too bad, and far gone. (Best left for another discussion).
Occasionally there were exceptions. But rarely. So rare in fact, they stood out like shining beacons in a stormy sea. Somehow you instinctively appreciated their value and actually paid attention. And yes, they seemed to share universal traits. Patience, understanding, empathy, respect and encouragement.
You remember them so many years later as they form part of your understanding and inevitable appreciation of the world.
There is no single method to this, no magic formula, as the best teachers are as different as the subjects they teach.
Ultimately there should be no communication obstruction, no inhibition. This would surely be the communication between mother and child, as ideas and thoughts are conveyed as if by osmosis.
