The debate between knowing facts vs knowing how to get to the facts<\/em> is a hallmark of the discussion about the ‘education for future’, with the pendulum of opinion often swinging between the two opposite positions. In this article Nicholas Alchin <\/strong>brilliantly articulates some of the issues involved in this debate.<\/span><\/p>\n\n\n\n

Students often ask why do we need to know this when we can just google it? <\/em>It\u2019s a great question, and it might indeed seem that with the internet as the fount of all knowledge, with facts only ever a click away, that there is less need to commit them to memory. It also seems to fit with the correct claim that creativity, critical thinking, communication, collaboration<\/em> and other skills (some of which do not begin with \u2018c\u2019) are what we should be seeking to develop in our children, and we should therefore leave knowledge acquisition to focus on them instead.<\/p>\n\n\n\n

However, the conclusion that knowledge is no longer important is profoundly mistaken for several reasons. I don\u2019t want to focus here on the fact that relying on the internet for facts seems to have pushed us down a rather dark extremist path in recent years – but rather on something more fundamental to our cognition. The point is the rather counterintuitive one that it is precisely because skills like creativity and critical thinking are so important that we need to concentrate on knowledge. Let me explain, using examples from psychologist Daniel Willingham.<\/p>\n\n\n\n

Take this sentence: Anna believed David when he said he had a house beside a small lake, until he said it was only 40 feet from the water at high tide<\/em>. Anna was able to spot a problem in David\u2019s claim because she knew something about lakes – namely that they do not have tides. If she had not known this, she would not have ever thought to look it up; or had she looked up \u2018lakes\u2019 she would have still been reading about geographical features long after David left the room. The point is clear – you need to know things; but it\u2019s not obvious which things. And these are things that we cannot possibly specify in advance. How would Anna have known to brush up on tides and lakes before listening to David talk about his new home? Or consider: \u201cI\u2019m not trying out my new barbecue when the boss comes to dinner!\u201d Mark yelled.<\/em> We can automatically imagine the situation and likely understand the sentence. In doing so, we are drawing on knowledge about employment, status, barbeques, cooking with new equipment, social etiquette, and embarrassment and so perhaps can empathise with Mark. And again, we have to have all this in our heads so we can piece it all together – if you didn\u2019t, we wouldn\u2019t even know what we were missing, and what to look up.<\/p>\n\n\n\n

The issue goes further than just understanding; it also affects problem-solving capacity. Consider the countdown-type problem shown in the diagram.<\/p>\n\n\n\n

\"\"<\/figure><\/div>\n\n\n\n

Now, most people quickly see that (25 x 4) + (9 x 3) = 127 but only because most adults know automatically, without needing to calculate it, that 25 x 4 = 100, and 9 x 3 = 27, without any conscious effort or need for a calculator. If you didn\u2019t just know these facts, at some deep level, then you wouldn\u2019t know to work them out. You\u2019d have to resort to the absurd mention of trying out various combinations (eg (9 + 4) x 25\/(2 + 3) – of which there are several hundred thousand. Interestingly, the more facts you know, the more different and creative solutions you might find. Someone who knew, who just \u2018saw\u2019 that 125 = 25 x 5 might come up with 25 x (4 + 1) + 2 = 127; a mathematician who knew that 27<\/sup> = 128 or 5! = 120 might well get to 2(3+4)<\/sup> – 1 = 127 or (4+1)! + 9 – 2 = 127.  These are what we could typically call ‘creative’ but are completely based on firm knowledge that’s deep in memory.<\/p>\n\n\n\n

So creative or critical thinking doesn\u2019t somehow happen separately to what we know; facts are the bricks from which we build creative and critical structures. That\u2019s why there is a fundamental and massive difference between things on google and things in our brains. If it\u2019s not in long-term memory, it\u2019s useless for critical or creative thinking. Looking it up just doesn\u2019t cut it.<\/p>\n\n\n\n

So if knowledge rich people have the capacity to understand more, to exercise greater critical analysis, to solve problems more readily, and even to be more creative<\/strong>, what does this mean as we seek to develop these skills? What does knowledge rich schooling look like? Well, contrary to many stereotypes, we do not need to adopt drill-and-kill and rote learning pedagogies. That won\u2019t work because it\u2019s simply not how people naturally learn. Take the information needed to understand the barbeque example from above – it\u2019s not reducible to a list of facts, but it might be gained through social interaction with others, reading books about everyday life, discussions, dinner-table conversation, experiences of cooking, and so on – in other words, engaging in a rich life of varied experiences. The same transfers to the numbers example; beyond the basic timetables (which should be memorised) fluency and familiarity cannot possibly come by learning randomly 27<\/sup> = 128 or 19 x 14 = 266 because there are simply too such facts to learn, because the facts would then be unconnected, and because most student would die of boredom. So to develop that knowledge we need to expose students to a rich range of situations involving number patterns and number relationships – puzzles, investigations, problems and so on.<\/p>\n\n\n\n

All this speaks to varied, open work at school that exposes students to a lot of facts in meaningful contexts.  If they collaborate and communicate on the basis of these facts then it will lead to deep knowledge that will support creative and critical thinking.  So the knowledge emerges not as the end-product, but as a by-product of engaging in thoughtful, conceptually based tasks. It\u2019s not so different to what we all want in most spheres of life – to retain the best of tradition, and to combine it with the best of new, progressive thinking too.<\/p>\n\n\n\n
