You were taught correctly about the movement of electrons.  No question 
about it.  It turns out that it was our old buddy Ben Franklin who 
guessed wrong. For many years "current flow", or as it is sometimes 
called "conventional current flow" has been  traced from the positive 
source to the negative one.
