Sugata Mitra, the Granny Cloud, and the Coaching of Teachers

In 1999, Sugata Mitra cut a hole in the wall of his office in Kalkaji, New Delhi. On the other side of that wall was a slum. He embedded a computer in the hole, with the screen facing into the slum. He turned it on. He walked away.

Within hours, children who had never seen a computer were browsing, drawing, playing games. Within weeks, they were teaching each other.

Mitra’s “Hole in the Wall” experiments, and the work that followed, the Self-Organised Learning Environments (SOLEs), the Granny Cloud, and the School in the Cloud, all point to one quietly subversive idea. Children learn extraordinary things when adults step back.

It is an idea that has shaped a generation of thinking about pupil agency, inquiry-based learning and the limits of direct instruction. We think it has something to say, too, about how we develop teachers themselves.

The teacher who isn’t watched

The dominant model of teacher development still rests on observation. A senior colleague sits at the back of the room. A clipboard appears. A judgement is formed, recorded, and returned. The lesson is, in a real sense, being performed for the observer.

For most teachers, this is an unusual cognitive state. They are not teaching as they normally teach. They are presenting a version of teaching that they hope will be approved of. The data harvested from these moments is shaped, inevitably, by the act of observation itself.

Mitra’s children, by contrast, learned without anyone over their shoulder. There were cameras, but no interventions. The presence of the recording device was not a panopticon. It changed nothing about how the children behaved, or what they tried, or how often they failed in front of each other. The absence of the watching adult was not incidental to the learning. It was the condition of it.

Starlight rests on the same intuition, applied to professional growth. A teacher records a whole lesson on their own terms. The audio becomes a transcript. The transcript becomes a private coaching report, returned to them within minutes. No observer in the room. No clipboard. No performance.

Just a teacher, teaching as they normally teach, and a structured, evidence-grounded mirror held up to the work afterwards.

Learning at the edge of chaos

Mitra describes learning as an emergent phenomenon, something that arises at the edge of chaos when a system is given a little structure and a lot of trust. Too much instruction kills it. Too little leaves it directionless.

That principle has shaped the way we have built Starlight. Reports do not tell teachers what to do. They surface patterns: where questioning opens up thinking and where it closes it down, where pace serves learning and where it overrides it, where talk is balanced and where it is not. The teacher decides what to do with the pattern.

This is closer in spirit to Mitra’s “method of the grandmother”, admiring, encouraging, asking the right questions from over the shoulder, than to the directive feedback culture that often surrounds teacher observation. The platform is designed to behave a little like a Granny Cloud. Warm, knowledgeable, present at a distance, but never the one steering the lesson.

The cloud, scaled

There is one more lesson worth carrying across.

Mitra did not stop at one classroom. He built a network. Hundreds of “grannies”, thousands of children, dozens of countries. The point of the cloud was not just that adults could be remote. It was that they could be distributed, available, abundant. Children in remote villages could draw on a network of mentors that no single school could ever staff.

Coaching for teachers has historically suffered from the opposite condition. Scarcity. One coach, one mentor, one Assistant Head with too many people to support. Most teachers, in most schools, never meet a coach in any sustained way at all.

Starlight is, in part, an attempt to do for coaching what the Granny Cloud did for encouragement. To make a high-quality, personalised, supportive presence available to every teacher, in every classroom, on demand. Not as a replacement for human coaches, but as a way of multiplying what they can reach.

An aside, for the SOLE-curious

There is a practical extension of all this that is worth flagging here.

Teaching in a SOLE is hard. It demands a different posture. Less direction, more provocation. Less explanation, more silence. The teacher becomes, in the often-quoted phrase, a guide on the side rather than a sage on the stage. For most of us, trained in a culture of explicit instruction, that is a difficult role to occupy with any consistency.

It is also exactly the kind of practice that benefits from a private, evidence-based mirror. We are developing a Starlight template designed specifically for SOLE-style and inquiry-led lessons. It looks at the ratio of teacher to pupil talk, the proportion of open to closed questions, comfort with silence, and the frequency with which teachers redirect pupils to each other rather than to themselves.

If you are training teachers to facilitate rather than instruct, that kind of evidence is gold. We would very much like to put it in their hands.

A coda

Sugata Mitra has said, in different ways across many talks, that education is not about making learning happen. It is about letting it happen.

That is a hard sentence to live by, even when you build a coaching platform for a living. The temptation to instruct, to grade, to direct, is everywhere in education. We have tried, with Starlight, to build a tool that resists it. Something that gives teachers the space, the privacy and the evidence to let their own learning happen.

We think Mitra would recognise the shape of what we are doing. We would very much like to find out.

Spark Insight with Starlight. And let the learning happen.

The Insight Engine is written by Adam Sturdee, co-founder of Starlight, the UK’s first AI-powered coaching platform, and a senior leader with responsibility for teaching, learning and coaching. This blog is part of a wider mission to support educators through meaningful reflection, not performance metrics. It documents the journey of building Starlight from the ground up, and explores how AI, when shaped with care, can reduce workload, surface insight, and help teachers think more deeply about their practice. Rooted in the belief that growth should be private, professional, and purposeful, The Insight Engine offers ideas and stories that put insight—not judgment—at the centre of development.
