all-in-one

[guzhi]

Hi,

I have trouble figuring out if the highlighted words are OK to use:

This is an all-in-one model.
This is a standard model.

Which word is better?
-This model/method/technique/strategy should be effective for teaching second/foreign languages by all means. (Is there any difference between second/foreign languages?)

Many thanks!

Can someone help me with this one? Thanks!
