I'm working on a paper right now to explain this additional language acquisition formula, but I wanted to put it on my blog to peak people's curiosity. This formula is tweaked for vocabulary acquisition, but it is the same as my one for additional language acquisition. Here is the breakdown:
f = focus on form
s = strategies
i+1 = comprehensible input
2 = interaction
m = motivation
i = identity
t = teacher effects
VA = vocabulary acquisition
