The alternative theory is that dragon slayers were shown all the moves before, but can only perform the more advanced ones as they become more powerful. Given the lack of structured training that we see in FT, that's hard to justify though.

If it's not Isuzu-chan Mii~
To be fair we have seen some training, and have been led to believe more happen outside of the screen. The constant fights themselves are the best kind of training fighters could have, aside from coming up with complicated techniques, as at least the theory would need to happen outside of an intense fight. But then again, the main characters rarely use too complicated magic. The dragon slayer magic is for a large part so animalistic or intrinsic looking that it almost makes sense there could be few theory lectures. The dragons are likely born with most of it. Perhaps the dragon slayers got an injection of dragon blood or something to begin their transformation... The second generation lachrima implantation could be a replacement for that, as no dragons were around anymore.
