Teach both. Students need to know that letters have names and sounds.

2. Sounds are used in pronunciation:
Adults will of course catch on much quicker than children, but age has nothing to do with and shouldn't have anything to do with teaching the alphabet, no matter the language, because they represent the symbols of written and spoken language.
The symbol "A" is called [e:]. That's its name, and it has more than one sound; e.g., [ae] as in a
pple and [a] as in fa
ther, and so on.
