SCHULVERSUCHE

Hier sei auf die vielen Schulversuche mit Esperanto hingewiesen, die im letzten Jahrhundert in vielen verschiedenen Ländern durchgeführt wurden und immer wieder aufs Neue die Effizienz und den propädeutischen Wert des Esperanto-Lernens bestätigt haben. Eine interessante Zusammenstellung dieser Versuche existiert in der englischsprachigen Wikipedia:

Zitat aus der englischsprachigen Wikipedia
(vom 2. März 2010, aktuellen Stand siehe: Wikipedia: Esperanto - Language Acquisition)

Four primary schools in Britain, with some 230 pupils, are currently following a course in "propedeutic Esperanto"that is, instruction in Esperanto to raise language awareness and accelerate subsequent learning of foreign languages under the supervision of the University of Manchester.[32] Studies have been conducted in New Zealand,[33] United States,[34][35][36] Germany,[37] Italy[38] and Australia.[39] The results of these studies were favorable and demonstrated that studying Esperanto before another foreign language expedites the acquisition of the other, natural, language. This appears to be because learning subsequent foreign languages is easier than learning one's first, while the use of a grammatically simple and culturally flexible auxiliary language like Esperanto lessens the first-language learning hurdle. In one study,[40] a group of European secondary school students studied Esperanto for one year, then French for three years, and ended up with a significantly better command of French than a control group, who studied French for all four years. Similar results have been found for other combinations of native and second languages, as well as for arrangements in which the course of study was reduced to two years, of which six months is spent learning Esperanto.[41]
