I agree. Many teachers I know are trying to embrace this style of education within the traditional environment. It is exciting to see students really engaged with learning, directing their own learning and also teachers redefining the learning space so that it is a productive child-centred space...one that does not revolve around the teacher and their desk.
Starting fresh in refugee areas means that these communities can be given meaningful learning opportunities that meet their needs.
I agree that passion, interest and real life problem solving are key to learning. Many 'traditional' schools are beginning to facilitate education in this way. I think relationship is key. People are motivated to learn when they are inspired. Inspiration and passion can be cultivated through relationship.
Having parents involved is a good idea. An, if they do not have the required skills, why not have the parents and kids learn side by side. Create community of learning. I don't think that learning should just be for the children. Having parents involved would hopefully help the children feel safe and will provide meaningful relationships. It would also help cultivate community passion and mean that real life problems will be met by all people in the community, not just the children.
Start with a small, real issue. Something that they can be successful in solving. Create passion and interest and motivation through this.
