I've always wondered why we don't experiment a bit more around children teaching children. I appreciate it can be a bit of a can of worms but it would help the system be more self sustaining.
The only reason I'm interested in this approach is that education itself is a massive expense which is often deprioritised in budgeting due to the fact that children do not vote, so it relies on the voting of parents to coalesce around a party specifically seeking to invest, which is difficult and unreliable.
Very interesting... at face value it doesn't seem sustainable, extendable or consistent. Perhaps you need to elaborate more on what you mean about children teaching. That being said the "learn one, do one, teach one" model it great and I recall giving and receiving a lot of peer assistance when I was young.
