"The important thing is not so much that every child should be taught, as that every child should be given the wish to learn" - John Lubbock.
In the TED talks, Shukla Bose tells the story of educating the poor in India’s slums through her groundbreaking Parikrma Humanity Foundation which brings education to the deprived group. As Bose puts it, the goal of the foundation is to help build a better India by tapping its greatest strength: the vitality and potential of its people. "Education of children is at the core of our aim to transform poor communities into self-sustaining, contributing communities, says Bose. The vision is to see every street and slum child gets the opportunity and access to education. She adds"We also believe that it's the content that is more important…it's not the infrastructure, not the toilet, not the library, but it's what actually happens in the school, that is more important, creating the environment of learning, of enquiry, of exploration,…is what is true education". (Alternatively, you can watch her presentation at the TED website and read the discussion thread about the presentation).
Another example of unsung hero is Master Ayub, who has taken the initiative of running an open air school for the children of slum dwellers in Islamabad, Pakistan. He has transformed the lives of these poor kids with virtually no help from the government.
