Understanding the essentials of cognitive architecture is a wonderfully liberating thing. So many of our misconceptions about education, our own and our pupils’, can be laid to rest.
The first, and most important principle is the understanding of what education actually is: changes in long term memory. This simple definition can and should be refined, but it’s an essential starting point. If you haven’t remembered it, you haven’t learned it. You were wasting your time, as teacher, as a pupil, if the knowledge which you were supposed to acquire has not at least begun to make its way into your long term memory.
This affects the questions we ask about teaching. Instead of chasing endless proxies for learning, we begin to focus on the thing itself. Instead of asking ‘were the pupils engaged?’ or ‘did they enjoy the lesson?’ or ‘did they write lots in their books?’ we can simply ask ‘what did they remember?’ In the end, that’s all that matters.
But that question logically leads to others. If we are interested in long term memory, we have to be interested in the long term. We are therefore liberated from the obsession with individual lessons as units of learning. We must ask ‘what did they remember the next week, the next month, the next year?’ Now we are able to see education as a coherent long term programme for building mental schemas in the minds of pupils, not a series of isolated fragments which could be judged as ‘outstanding’ or ‘satisfactory’.
These are just a few of the ways in which understanding cognitive architecture liberates us professionally. But there is a wonderful personal liberation too. So often I have complained over the years about how poor my memory is. Recently, when I was explaining to a colleague how much explicit memorisation I require of pupils, he said, ‘My memory’s rubbish. I suppose you have trained yours to be able to do this?’ From his tone, it sounded like he thought such ‘training’ would require Herculean efforts, beyond the capacities of most ordinary mortals.
But when we understand that we all have extremely limited working memory, but practically limitless long term memory, and that repeated practice and testing can ensure that anything can be securely stored, then we know that we do not have a rubbish memory. We have a human memory, and we face the same limitations and have the same amazing potential as the rest of the human race. The obstacles we face to filling our memories with countless treasures of poetry, history and science are obstacles that we, and our pupils, can overcome with persistent, faithful, steady effort.
It is also a wonderful liberation to realise that we have not, in fact, forgotten most of what we learned in school. Every well educated adult has a vast store of tacit knowledge which enables her to read a wide range of texts, as well as listen to other articulate, educated adults and take part in intelligent conversation with them. It is amazing to consider just how much we do, in fact, remember, but this also places a solemn duty upon us. When we realise how much we know, we appreciate how important it is that we should pass this on, so that succeeding generations can also take part in this conversation. And we’ll never succeed in doing this unless we talk to our pupils!
So with the excitement and liberation of discovering the reality of how the human mind works, come solemn duties: to pass on knowledge, and to fight against the ideas which prevent us, or our colleagues, from doing so, such as ‘education is what’s left when you’ve forgotten everything you learned at school’.
These ideas are so often glibly repeated in staff rooms or displayed on classroom walls, and they strike at the very root of what education is, and even what human beings are. To fill the mind with knowledge, and to treasure this knowledge and pass it on to succeeding generations, is to perpetuate human civilisation. To refuse to do so is to abdicate from one of the most fundamental human responsibilities.
