Yes, I totally agree with you Oscar.
I think that the language schools are not interested, nor are willing to look at, other ways of teaching their students.
The majority of language schools are stuck in their ways and will not change their methods at all because that’s what they sold in the first place.
But, how about they looked at othey ways? This is the problem. When you step outside the ‘norm’ you end up getting ridiculed and told “no, that’s not normal”, so you step back inside the ‘norm’ box.
