My own experience is that in a school environment, it is more condusive.
The child concentrates better, and the teacher teaches better. How many times have we, working adults, try to tele-commute and work from home, and it ended up being an unproductive day, because you get distracted by all sorts of things?
Of course the regular performances organized by the school helps greatly in ensuring a well rounded training.
Koolmama:Actually I don't understand why parents want to go to music schools for 1-2-1 lessons. It is so much better learning from a private teacher in his house or your own house. At music schools, you have to pay registration fees, parking fees and rescheduling of make up lessons is often difficult or sometimes not even allowed. They also tend to sell violins at marked up prices (Wolfgang, for example, sell their cheapest violins at $280 whereas you can get the same quality from Synwin for only $120+). My child's private teacher is contactable via SMS 24 hours a day whenever we need to ask him any questions, and he even gives us advice on how to choose violins, bows etc (he is very knowledgeable about pedagogical issues and instrument-related issues) He will even come with you to help you choose and buy a violin, and help you get discounts. There are no registration fees to pay and his own fees are cheaper-per-minute when compared to those charged by music schools, And, he is also better qualified than most teachers I've seen in many music schools!
Just giving my honest feedback here
