Organise: structure what you are learning#

You’ve explored your material and you understand it. The temptation now is to dive straight into memorising — open the flashcards, start the repetitions. Resist that for a moment. There’s a step in between that pays for itself many times over: shaping the material so it’s easier to hold and easier to keep. I call this organising. Older versions of this manual called it arrange, and you’ll still see that word on the pages below.

Here’s why it matters, and it comes down to one stubborn fact about your head.

Why organising works: the narrow door#

Everything new you learn has to pass through working memory — the small mental workspace where you hold and juggle whatever you’re thinking about right now. And that workspace is tiny. For a long time the figure people quoted was “seven, plus or minus two” items, from a famous 1956 paper by George Miller. That number turns out to be generous. When you stop people from quietly grouping or rehearsing, the real capacity for separate, unrelated items is closer to four (Cowan, 2010). Four. That’s the door everything you learn has to fit through.

This is the heart of cognitive load — the idea, well established in instructional research, that learning suffers when you ask working memory to hold more than it can (Sweller, van Merrienboer & Paas, 2019). A wall of forty disconnected facts overwhelms the door. The same forty facts, sorted into five groups of related ideas, sail through — because now you’re holding five things, not forty.

So organising isn’t tidiness for its own sake. It’s how you stop overloading the door. Three moves do most of the work:

Chunk it. Group small items into larger meaningful units. A “chunk” can be one item or a whole cluster, so grouping items shrinks how many slots they take (Cowan, 2010). A phone number isn’t ten digits, it’s three chunks. The trick is to build chunks that mean something — and as you get more expert in a subject, your chunks get bigger, which is much of why experts seem to hold so much at once (Gobet et al., 2001).
Find the structure. Look for the shape underneath the surface — the hierarchy, the sequence, the cause-and-effect. Material with an obvious structure is far easier to take in than the same material as a flat list, because the structure itself does some of the holding for you.
Build schemas. A schema is an organised pattern in long-term memory — your mental “template” for how a kind of thing works. Once built, a whole schema acts as a single chunk when you call on it, which is exactly how a skilled person sidesteps working memory’s limit (Sweller, van Merrienboer & Paas, 2019). Every time you connect new material to what you already know, you’re growing one.

The single instrument that does all three at once is a concept map — boxes for ideas, labelled arrows for how they relate. This is the worked tool of the Organise step. Drawing one forces you to chunk the material, find the structure underneath it, and make the connections explicit — which is to say, it is schema-building made visible on the page. Reviews of concept and knowledge mapping find it a modestly effective study aid, a bit better on average than re-reading or making plain notes (Nesbit & Adesope, 2006). It isn’t magic, and a half-hearted map won’t do much — the value comes from the thinking you do while building it.

Then add one move that turns the map from a picture into learning: once you’ve built it, put it away and redraw it from memory, then check the original for what you missed. The gaps are exactly what you don’t yet know. That self-test is retrieval practice , and it’s where a map earns its keep. The same map recurs at every grain of the learning cycle — a course map is a concept map at its coarsest, and when you practise and review you redraw the same map to find your gaps. Here you build it. For the full catalogue of map types — spider, hierarchical, systems, and more — and how to use them, see the Concept and Mind Mapping course .

What learning actually does to your brain#

Worth being straight about the biology, because older accounts (mine included) oversimplified it. When you learn, your neurons don’t sprout new bodies and march around; what changes is the connections between them — synapses strengthen, and with durable learning, new connections form. Repetition and use drive that change, which is genuinely a little like training: do it once and little sticks, come back to it repeatedly and the pattern holds. That loose parallel — practice reshaping the brain the way training reshapes the body — is truly where the athletics in “Memletics” came from. Just don’t take “synapses are like muscles” too literally; the brain is more plastic and more interesting than that metaphor suggests, and it keeps forming new connections throughout adult life.

The practical upshot is the same either way: lasting learning is built, by repeated, connected work — not poured in once. Organising is how you make that building efficient.

The three steps of organising#

Like the rest of Memletics, you scale this to the job. A simple objective needs barely any organising; a complex or important one rewards doing it properly. Three steps:

Analyse content #

Work out what kind of knowledge you’re dealing with — facts, concepts and principles, skills, procedures, higher-order thinking — and how you’ll need to use each piece. Different knowledge types reward different techniques, so naming them first makes the next choice much easier. This is also where you break a topic into chunks you can sort.

Choose your retention approach #

Decide what genuinely needs memorising versus what you can look up, then pick the techniques that suit each chunk. You don’t need to memorise everything — and resisting that urge is half the skill. Combine techniques rather than hunting for one silver bullet.

Prepare for application#

Once you’ve chosen your techniques, shape the content to fit them before you start drilling. Each technique wants its material in a particular form: a sequential or linked list for association and peg methods, a vivid scenario for visualisation, a few key points written into a script to verbalise, a complex task split into parts for part-task practice, or question–answer pairs for flashcards and spaced repetition. Spend a little effort turning your raw material into the right shape here, and the practising that follows goes far more smoothly.

Get this phase right and the hard work that comes next — the actual practising — lands on material that’s already been shaped to fit your head. That’s the whole point.
