I agree with you completely - It's often better to keep your mouth shut and have people think you an idiot, than to open it, and prove it.
And yet you continue to not only make yourself look like an idiot, you manage to broadcats it very loudly indeed.
If you think children will learn anything from tinkering with a Raspberry Pi you want to visit a mental health institute.
Clearly you have a severe case of rectocranial inversion or you would know that there are a large number of project being make by kids for the Pi. Try google. You might find something that way.
They would be better off learning using a Windows PC and the vast variety of software it brings. This route would be more beneficial and economical since schools already have donated PCs.
Ah, yes, the PC. You mean that platform that is slowly sinking into the mire of dead computer platrforms alongside such luminaires as Kaypro, Dragon and Amstrad, to name but a few. Please note that there are more operating systems out there besides Windows and this will help schoolkids learn that the computer world is not a single OS world.
As for learning basic electronics a Microchip PIC and a breadboard would be ideally suited. The microcontroler and breadboard can be bought for under 10 pounds from maplins. A variety of circuits can be constructed to understand the basics.
And then once they have gone past those very simple items? What then?
Do you really think children are capable of understanding SPI and USB protocols. If the Raspberry Pi is so great why don’t you try and convince the developer community instead of children.
Not at first, But they can learn, and the Pi is a great, affordable platform for them to learn on. and the advantage of the Pi and it's prioce is that it one does get broken, it does not cost half the schools IT bidget to get a replacement and it also0 means the school doesn't have tyo go cap in hand, begging for a replacement computer.
