I'm thinking... Our improvement over the 180 days is measured mainly just by the Dialang tests which only tell you your CEFR level (A2, B1...) and not precise scores. But is 180 days enough to improve by 1 level so that you can see improvement? Chances are we'll improve from B1.1 to B1.5, which means we'll score B1 both pre- and post-study. What gives? Number-crunching:
FSI hours class + homework:
Cat I 1080 hrs
Cat IV 1980 hrs
We tend to take twice as long and then only reach B2:
Cat I 2160 hrs ( 2.5 hrs a day x 2.4 years )
Cat IV 3960 hrs ( 2.5 hrs a day x 4.3 years )
= average 3060 hrs ( 2.5 hrs a day x 3.4 years ) or ( 2.5 hrs a day x 1224 days )
Assume the time spent to reach each level is:
A1 ... 10%
A2 ... 20%
B1 ... 30%
B2 ... 40%
Then it takes:
From A0 to A1 ... 122 days
From A1 to A2 ... 245 days
From A2 to B1 ... 367 days
From B1 to B2 ... 490 days
Which means, over a 180-day period, only the improvement of participants advancing from A0 to A1 are sure to show in the Dialang results. The improvement of other participants may or may not show - will show if they start the study at the end of a level (B1.9, etc), won't show if they start at the beginning or middle of a level (A2.1, B2.5, etc).
Let's look at Cat I and Cat IV separately.
FSI hours class + homework:
Cat I 1080 hrs
Cat IV 1980 hrs
We tend to take twice as long and then only reach B2:
Cat I 2160 hrs ( 2.5 hrs a day x 864 days)
Cat IV 3960 hrs ( 2.5 hrs a day x 1584 days)
Assume the time spent to reach each level is:
A1 ... 10%
A2 ... 20%
B1 ... 30%
B2 ... 40%
Then it takes:
Cat I A1 ... 086 days
Cat I A2 ... 173 days
Cat I B1 ... 259 days
Cat I B2 ... 346 days
Cat IV A1 ... 158 days
Cat IV A2 ... 317 days
Cat IV B1 ... 475 days
Cat IV B2 ... 634 days
Similar. Need further number-crunching to say "most", but at least "a lot of" participants will score B1 both pre- and post-study, and even more will score B2 in both tests.
