Learn by playing (game)
A concept which was introduced by Jan Amos Komensky in the year 1630 when he published (in Czech) Škola hrou (Schola Ludus, School by Playing). Actually the original Czech title "Škola hrou" has a double meaning. Beside "School by Playing" it also means an "easy" or "enjoyable" school(ing) / learning. What he was preaching was he also practicing. He came back to this concept when he opened a new school in Sarospatak (Hungary) in 1651 and wrote another related book Orbis Pictus ("The Visible World in Pictures") which was the first fully illustrated textbook.
According to WIkipedia (http://en.wikipedia.org/wiki/John_Amos_Comenius) he was "earliest champions of universal education, a concept eventually set forth in his book Didactica Magna. He is considered the father of modern education.[6][7] Comenius was the innovator who first introduced pictorial textbooks, written in native language instead of Latin, applied effective teaching based on the natural gradual growth from simple to more comprehensive concepts, supported lifelong learning and development of logical thinking by moving from dull memorization, presented and supported the idea of equal opportunity for impoverished children, opened doors to education for women, made instruction universal and practical. He lived and worked in many different countries in Europe, including Sweden, the Polish-Lithuanian Commonwealth,Transylvania, the Holy Roman Empire, England, the Netherlands and Royal Hungary.
