Ἕν, δύο, τρία draws on a new technique for language acquisition developed at the Polis Institute of Jerusalem, Living Sequential Expression (LSE), which was inspired by two ideas of François Gouin: the influence of sequentiality in the learning process, on the one hand, and the need to express basic human experience through the language being learned, on the other hand.
This is why most of the pages of Ἕν, δύο, τρία show sequences of actions to be heard and seen, and to then be enacted and retold by the learner. These sequences respect the inner structure and dynamics of the target language. By doing so, the process of internalizing a language becomes swifter and more efficient, as language features are acquired according to an overall natural sequence, given that specific pragmatic features naturally precede others. This is what the pragmatic progression of Ἕν, δύο, τρία intends to reflect.
