Palope is a Fibel developed by prof. Christa Röber (Germanistik / Pädagogik, Uni Freiburg) and her team

the essence of Fibel is the scaffolding sequence - from simplest syllables to evermore complex structures

in Palope, the trochaic structure of German language is exploited to maximum to facilitate the Einstieg in the world of written letters

good design choices (not phoneme-driven but syllable-driven) many interesting inovations (color coding of different syllable types) and cognitivelly powerful methods (e.g. "Silbentepiche")

and it is a community project ! (e.V., all OERs under Creative Commons etc.)

Time for a little demo
