I had to fight to convince Charliche that giving English classes to the kids could be useful, but finally made my point. He thought first that the problem was continuity, as once the volunteers are gone the kids loose everything. I think personally that any course is good to take, and especially for those who learn English at school and actually want to learn. Also it is important to teach the kids the importance of foreign language, how much an asset it can be when mastered.
At the favela of Prazeres, we gathered a small group of 14/16 years old who had already taken some courses at school. Two mornings per week, I gave them English courses in the community centre of the favela, using 'whatever was available'. Tiny blackboard, no book, no audio-visual support, noise around. But as a volunteer, we learn to cope, and by a way or another we always get to where we aim to end.
After 4 weeks of classes I was satisfied with the course. The children, although undisciplined, were voluntary and assimilated several concepts very well. They also understood the importance of learning a foreign language, and that besides being able to flirt with foreign girls they will also be able to find a better work!
It was hard though to see all these children with strong potentials, but victims of the environment in which they live. They can succeed in life but are constantly braked (not to see blocked) by the system of the favelas.
