What we did
We took three sections of Class 8 (40 children each) and taught them in three
different ways for about three weeks:
- Section A — not taught. They carried on as usual. This is our comparison group, so we
can see how much children change anyway.
- Section B — taught using the computer. The interactive website (pattern, sorting,
training, pixels, compression, next-word).
- Section C — taught using activities. The same ideas, but with cards, drawing,
sorting games and role-play — no computer.
The test (same one before and after)
Every child wrote the same short test, out of 20 marks, once before the three weeks
and once after. A child who scored 12 or more out of 20 is counted as
having understood it well. The test asks simple things in the child's own words — for example:
- “What comes next? 🔵 🔴 🔵 🔴 🔵 ___”
- “If a machine only ever saw brown dogs, what mistake might it make with a white dog?”
- “True or false: AI is always correct. Why?”

How many understood it well (scored 12+ out of 20)
| Section | Before | After |
|---|
| Section A | 5 of 40 | 13 of 40 |
| Section B | 6 of 40 | 25 of 40 |
| Section C | 7 of 40 | 30 of 40 |
What this shows
Section A (not taught) hardly changed — about +1.5 marks.
Both the computer group (+4.4) and the activities group
(+4.6) improved much more.
The two taught sections improved by a similar amount, so both ways of teaching work —
a school can use the computer, the hands-on activities, or a mix, depending on what it has.
