In Finland the educational system, as it is today, was build slowly. It is still strongly relying on the work of Uno Cygnaeus ( 1810-1888 ) who was influenced by the early European “constructivist” Pestalozzi ( 1746–1827 ) and Froebel ( 1782 –1852 ). The idea that children learn the best when they areactive and build things was not really invented by John Dewey or Piaget – they only were able to present the idea in a language of positivist science, when the earlier thinkers thought themselves as “pedagogues” or educational philosophers.
