Mogollón pioneered the creation of Escuela Nueva and the Active schools[1] approach, which are successful educational models that expanded throughout Colombia, Latin America, and Africa.
Mogollón devoted his entire life to creating new ways of improving the quality of education of the poorest children in the most impoverished rural communities.
He managed to take into practice the principles of Active school [3] and he proved that it was possible to deliver a better quality of education to the children of the most impoverished areas.
Later while working for AED (non-profit) as international Consultant for education in Guatemala, Nicaragua, Peru, Equatorial Guinea, he applied his experiences in Colombia and adapted the Colombian model to the needs, aspirations, contexts and interest of each country.
Knowing the limitations of a rural school and taking them into consideration, Mogollón started to innovate strategies to customize the learning process for each boy and girl according to their individual needs.
Mogollón changed the ways of thinking and attitude of teachers in Latin America and Africa, making them realize the key role they play in the quality of learning.
