The Multiplier Effect: Why Training One Teacher Can Change 150 Lives

By Coach Amirul Iskandar Mannan, CEO, Yayasan Wiba Prima

Picture a Year 4 classroom on a hot Tuesday afternoon.

The teacher is explaining the water cycle. Evaporation, condensation, precipitation. Three long words, a paragraph in the textbook, and thirty-five students trying to hold it all in their heads.

Some get it. Many nod politely. A few have already given up.

Now replay the same lesson. This time the teacher picks up a marker and draws. A sun. A few wavy lines rising from the sea. A cloud getting heavier. Raindrops. An arrow looping back to the sea.

Thirty seconds of drawing. Suddenly, the room can see it.

Nothing about the syllabus changed. The teacher did.

Where is the multiplier?

Every education programme eventually faces the same question.

Do we go directly to students? Or do we go to the teacher who reaches them every single day?

At Yayasan Wiba Prima, we chose the teacher. The reason is simple maths.

Train 1 teacher, and that teacher can reach around 150 students.

Multiply by 100 teachers, and the target becomes around 15,000 students.

That is the heart of our Visualization Through Freehand (VTF) programme in Johor this year. Not 15,000 separate interventions. One hundred well-equipped teachers, each carrying the method into their own classrooms.

The maths that doesn't fit on a spreadsheet

But the real multiplier is bigger than 150.

A student programme ends when the programme ends. A teacher's skill does not.

The teacher who learns to explain a difficult idea with a few simple lines will use it this year. And next year, with a brand new class. And the year after that. A skill invested in a teacher keeps paying out for an entire career.

We don't just train teachers. We multiply impact.

That is why we see teacher development not as a cost, but as one of the highest leverage investments a country can make in its children.

Why teach visually?

Visualization Through Freehand is exactly what it sounds like. Teachers learn to explain ideas through simple sketches, drawn by hand, in real time.

The first thing teachers usually say is, "But Coach, I can't draw."

Good news. You don't need to be an artist. If you can draw a circle, a line, a box and a stick figure, you can teach visually. VTF is not about beautiful drawings. It is about clear thinking made visible.

Why does it work?

• It gives students another doorway into the lesson. Not every child learns best from text and talk.
• It slows the lesson down just enough. Drawing forces the teacher to break an idea into steps, and students follow those steps as they appear.
• It turns listeners into participants. When students start drawing ideas themselves, they stop memorising and start understanding.
• It needs almost nothing. A whiteboard, a marker, a piece of paper. No device, no internet, no expensive kit.

That last point matters more than people think.

Leave no one behind, starting in the classroom

Many of the students we care about most come from B40 families or live with learning challenges. They are often the first to fall behind when lessons are fast, wordy, and abstract.

A simple drawing can be the difference between "I don't get it" and "Oh, I see."

Because VTF needs no technology, it works just as well in a well-funded urban school as it does in a small rural classroom. This is what Leave No One Behind looks like at classroom level. Not a slogan on a banner, but a teacher holding a marker and making sure every child can follow.

Training alone multiplies nothing

I want to be honest about one thing.

A great workshop on its own changes very little. Plenty of teachers attend an inspiring session, go back to a packed timetable, and within two weeks everything is back to normal.

So for us, training is only the beginning. What happens after matters more:

1. Follow-up coaching, so teachers keep practising after the course ends.
2. Classroom monitoring, so we see what is really happening, not what we hope is happening.
3. A community of practice, where teachers share what works and learn from each other.
4. Measuring impact on students, because that is the only result that truly counts.

150 students per teacher is our target, not a claim. We measure it. The people and institutions who trust us with this work deserve evidence, not slogans.

What this means for you

You might not be running a teacher training programme. But the question still applies to your work.

If you lead a school, ask: which one skill, given to every teacher, would lift every classroom?

If you lead a foundation or a CSR programme, ask: are we funding activities, or are we funding multipliers?

If you are a teacher, ask: what would change if my students could see what I am explaining?

Sometimes the most powerful thing you can do for 15,000 students is to invest deeply in 100 teachers.

A word of thanks

To every teacher in Johor who said "I can't draw" and then picked up the marker anyway: thank you. You are the real multipliers.

And to our partners who believe that teachers are the fastest way to reach children: thank you for walking this journey with us.

Train teachers. Empower students. Create impact.
