The issue here is that teenagers are also the most likely to rebel and ignore your orders / circumvent your "shielding" attempts, and also be already capable enough that you're going to lose most of the time. I'm not sure what the best solution is - giving regular (but not too frequent) and detailed real life examples of things that went horribly wrong with other teenagers, combined with total freedom (in this domain) - or reverse psychology combined with a heavy handed approach where they're going to quickly learn how to fool you and also how to hack your countermeasures, which would supercharge their learning ? (With the risk of a decade+ of bad relations...)
