Ahh, well it depends. Generally, when there is a time sig change like that, you need to specify which note value stays constant. It could be either way.
Above the stave you might see something like eigth = eigth (but with eigth notes instead of the word 'eigth'). That would indicate that the length of an 8th note stays constant - which would mean that the 6/8 bar would be as long as 1.5 2/4 bars. However, you could see quarter = dotted quarter (again, notes, not words) - and that (I think, but that could be the wrong way round, it could be dotted quarter = quarter, I forget) would indicate a quarter in 2/4 is equivalent to a dotted quarter in 6/8. That would mean that the main beat stays constant, but it goes from being divided into 2s to being divided into 3s. Like going from a straight feel to a swing feel.
