Not all teaching methods are created equal. And better methods produce better students. 

The flip side to this is that there are better ways to learn, and that not all learning methods are created equal. 

So whether it's learning a new language, learning to play the guitar, learning a martial art or learning about the spirit world, there exists a spectrum of possible learning styles ranging from the not so great, to mediocre, to good, to excellent and everything in between.
