Educational linguistics is transcultural, with research in the field adopting an international scope. Educational systems, on the contrary, are culture-bound. As a consequence, actual teaching differs across countries, and sometimes even among provinces, local educational authorities, and schools.

However, a globalized world needs to share the various meanings of “knowing a language” and “teaching a language”, as language is the main factor of both cultural identity and national and international interaction.

The framework offered here is built on eight “hypotheses”, logical models that provide the potential common core of a non-culture-bound theory of language education and of language teaching. The book thus suggests a common terminology, some common principles, and a basic paradigm to be shared in both theoretical and practical research in edu-linguistics, consequently going beyond the borders implied by such titles as European framework, American standards, and Chinese guidelines.
