As a kid I was a reasonable tennis player, having been coached by an expert and playing competitively from a relatively young age. Nothing outstanding, just competitive at a district level.
Aged about 16, my father who had been an outstanding player and myself started coaching on a Saturday morning on two local courts for a bit of pocket money. I discovered to my surprise, that breaking down, simplifying, and articulating to others the lessons I had absorbed from my coach, to enable me to communicate with those I was in turn coaching, made me a better player.
Recently in a (business) coaching session with one of my clients, we discussed for the 3rd or 4th time the concept of break even. How a break-even point is calculated, the discrimination between fixed and marginal costs, and the management value it delivers. The conversation started because it became evident that despite the previous conversations, my client did not understand sufficiently well to be able to implement in his business.
Therein lies the secret.
The discussion involved him explaining the concept of break-even back to me, while drawing a typical break-even diagram. It took prompting and discussion, but by the end it was clear he understood the meaning and value of calculating his break-even point.
The secret was him explaining it back to me, and demonstrating that he understood by drawing an illustration of how and why it worked. It required him to break down in his mind the elements of a break even into its simplest form. Then, explaining it back to me, as if I was someone who had absolutely no understanding of the idea. Drawing the diagram, enabled the understanding.
This simple act of writing down an explanation is the value that writing this blog delivers to me. I often start a blog with an interesting idea which requires research and building of understanding before writing it down in its simplest possible form. Through that process, understanding builds.
If you cannot explain something in a way that a 10 year-old can understand, you probably do not understand it well enough yourself. The greatest exponent of this technique of using illustrative metaphors to explain complexity in simple ways was Albert Einstein.
There is nothing like having to explain/teach something to someone else to gain a better understanding yourself. I passed 2nd year university genetics, then in my final year got a job tutoring first year Biology students. I gained such a better understanding (perhaps being proof that often exams are not a test of understanding)
Colin, I think it is a very common outcome. Teaching becomes a core to learning.
BTW, the client concerned emailed me almost immediately I posted it, claiming royalties. At least I now know he reads my stuff!
