Most of the voluntourism schemes are run by for profit companies, it's a billion pound industry, for the majority of cases it's a company not a community, so that's why they keep getting "invited back"
well, no its the community that keeps inviting us back.
(there's a school in machame Tanzania that anfriend of mine lives near that pretty much gets painted every year !)
so what! No harm done - the school is kept in good nick, the children have done something nice for someone, really, why is it a problem?
I know a school in Tanzania for which the only maintenance ever done is from the volunteers of a particular organisation. Without them, the school would have long since fallen down!
or the worst of the lot: teach at a school (seriously please no one send their unqualified 18 year old teen to teach at a school for 2weeks please, it is an awful, awful idea)
again, you don't really know what you are talking about. One school I have been in, has a few volunteers every year, and for many children, these few weeks are the only TA type support they get for the whole year. I know of children with ADHD, dyslexia, etc who just don't get any other help - and the school may only have volunteers for 6 weeks out of 52. it is a very valuable service to those children, and makes a big difference to them. Again, there are schools that cannot run a full time timetable without volunteers, and if they only have volunteers again for maybe 6 or 8 weeks a year, the children may actually only have 2-3 hours a day for the rest of the time.
Uk teens may well be "unqualified", but still have a lot to offer in the field of education, the reason being they are very experienced at receiving it! And have ideas and enthusiasm that can be put to very good use. It makes a big difference.
Volunteers are not just thrown in and told to get on with it. They are overseen and directed by the class teacher.
And I don't really hear anyone complaining about it happening in UK schools, student ambassadors for example volunteer for around 10 days each in UK schools, there are very few schools in London that don't take them, use them and benefit from them, although again, the benefit may well be mostly for the ambassador.
As for "unqualified teens" being a bad idea in schools in generals, how many unqualified young, or older people are volunteering or being paid in your local school?
Certainly, UK schools are in receipt of more volunteering than any of the schools we visit abroad. Many of these volunteers are young, many unqualified, and many short term. Again, the volunteer benefits as well as the school, its a two way thing. I don't know why you think it is a good thing for uk schools to run this way, but not schools abroad, where actually the need is far greater.
As for being unqualified, many staff in UK schools are unqualified, many teachers in the schools we visit are unqualified.
I have some reservations myself about some of the volunteeers, some of the expectations ( on both sides) and some of the schools visited, however, no more so than I do in the UK.
I have volunteered in schools in the uk, and abroad, I have benefited from both, and the schools I have volunteered for have benefited from me, and the teens I have brought with me, but certainly the schools abroad have benefited more. In those cases, you are talking about schools which could triple the hours they are open for the day at times when there are volunteers there, ie open 9-4pm when we are there, but only 10-12 when we are not. And with classes of 60+, often no books etc of course the teacher can give very little individual one to one attention, normally, and of course they benefit from having those extra pairs of hands for those few weeks.
I volunteered at one school some years ago, with three teens, and have sponsored one of the children I met ever since, so I keep in touch either the school, the teacher, and the class. They have had a couple of volunteers since, but for all except those few weeks, my bright enthusiastic, hard working little sponsee gets two hours of lessons a day, in a class of 70 with one teacher,
Why would you begrudge her the extra enhancement to her education that she occasionally gets from the uk "unqualified teenagers"?
