Black and White and Learned All Over

There was a running joke in the staffroom.

Anything black and white was very me.

While colleagues arrived at meetings with slides that looked like they had hired a graphic designer over the weekend, mine looked unfinished by comparison.

White background.

Heading.

Text.

Done.

People laughed about it affectionately. I laughed too.

But quietly, underneath that laughter, there was always the same uncomfortable question:

Am I missing something? Because teaching can feel performative sometimes.

Not intentionally. But visibly;

The polished slides.

The moving graphics.

The carefully selected fonts.

The educational stage production.

And sitting there with my plain white slides, I would watch the room react to everyone else's work and think:

God, that looks impressive.

I never doubted my teaching. But I absolutely doubted whether it looked like good teaching.

Those are not always the same thing.

We used to call it eye candy.

And schools are full of it.

Walls competing for attention. Slides flying in from every direction. Icons. Colours. Music. Movement. Endless decoration wrapped around the hope that if learning looked exciting enough, students would absorb more of it.

But over the years, I kept circling back to the same idea.

What if all that effort was costing us the very thing we were trying to create?

I had been reading about working memory for years. Not in some obsessive academic way. Just quietly. Curiously. At professional development days, I always drifted toward the cognitive science sessions. I kept finding myself pulled back to the same research, the same arguments, the same uncomfortable possibility that simplicity was not a lack of effort at all.

Maybe it was the point.

Still, there is a difference between suspecting something and feeling confident enough to stand behind it.

Then came the conference.

Huge room. Hundreds of schools. Speaker after speaker standing at the front referencing the same theories, the same research, the same conclusions I had been slowly assembling in my own head for years.

And I remember sitting there feeling something close to relief.

Not triumph.

Relief.

Because suddenly the thing that had made me feel inadequate looked less like inadequacy and more like instinct.

The model itself is deceptively simple.

Daniel Willingham describes memory as a process of moving information from the environment into long term memory. But before anything gets there, it has to squeeze through working memory first.

And working memory is painfully limited.

Think of it like a loading dock.

Everything is trying to land there at once.

Your voice.

The slide.

The scraping chair.

The student whispering beside them.

The animation spinning in from the left.

The bright background.

The decorative border.

The GIF.

The joke.

The colour.

And at some point, the dock is full.

Not because students are not trying.

But because they physically cannot hold any more.

That is the part we do not say loudly enough in education: decoration is not neutral.

It costs something.

Sometimes it costs the lesson itself.

My slides still look plain.

White background. Headings. Necessary text. Occasionally a symbol to trigger discussion, though that is more teacher instinct than science.

And yet the classroom is anything but empty.

It is alive.

Students erupt with ideas before I ask the question. Negotiating meaning with each other across tables. Elaborating. Arguing. Building connections out loud.

The simplicity on the screen creates space for complexity in the room.

That is the trade.

And I will take it every time.

But this does not stop at school.

The same loading dock exists at home too.

A child trying to complete homework while YouTube runs in the background, notifications buzz across their phone, tabs multiply across a browser and conversations drift through the house is not failing because they are lazy or unmotivated.

Their cognitive space is simply saturated.

Full dock. No room left for the maths.

And honestly, I think adults forget this because we have become so accustomed to noise ourselves. Constant input. Constant stimulation. Constant attention splitting.

Children are no different.

Attention is finite.

What fills it matters.

And over time, something beautiful happens in a simple classroom.

Repetition builds familiarity.

Familiarity builds safety.

And safety frees students to think.

Not about the slide.

Not about the colours.

Not about where to look.

Just the learning.

Just the idea.

Just the work of understanding something they did not understand five minutes earlier.

That is the real magic anyway.

Not the performance.

The thinking.

You might have noticed this blog looks a little plain too.

No moving banners.

No visual fireworks.

No eye candy.

Just enough space to think.
