This paper focuses on the implementation of an e-learning environment for the educational support of the deaf, as a paradigm of deaf inclusion in the Information Society. The developed platform allows structuring and presentation of Greek Sign Language (GSL) educational material and linguistic resources, addressing the needs of GSL grammar teaching to early primary school pupils. Linguistic content presentation is realized by applying dynamic sign synthesis through the use of avatar technologies for sign representation. The platform utilises standard techniques for the presentation of educational material in deaf classes but also allows tutors to modify educational material dynamically. Acceptance by students and tutors has been tested under the supervision of the Hellenic Federation of the Deaf.
