I am fond of Science since I was a child, heir to the pedagogical tradition of Comenius, Rousseau, Kant and Pestalozzi and a great defender of alternative teaching methods such as Decroly's, Ferrer i Guàrdia's and Suzuki's. I firmly believe in learning through play and observation, beyond grades meritocracy, and I teach to all ages in Catalan, Spanish or English, exceptionally, in French or Italian, Biology, History, Literature, Music, Philosophy, Language, Paleography and/or Religion.
