"I go to the north."
That's not as helpful; it gives hints but it doesn't tell us the structures nor does it explain why the structure is the way it is. ("north" is not a destination, which is why the directional particle へ is used. If this is wrong please correct me so I don't confuse anyone but myself.)
This is why I don't like the new feature of audio when you choose a word box, its pronunciation of へ is "hey" and not the correct "eh" as it should be used as a particle. For experienced japanese speakers this is no problem, but if someone is new to the language, they would get the wrong pronunciation of the particle へ.
I like the way they're doing it now because It generally uses the correct pronunciation when you click read out the whole sentence and when the exercise starts(at least i think so). As a beginner I can tell that it's not being pronounced in context the same as it is when I click on it individually... also if I'm curious what that character is i can find out what it sounds like stand alone.
