E-Learning, Fuzzy Methods, and Sign Language Video to Enhance Teaching for Hearing Impaired

This chapter discusses the e-learning methods that were used within the Dedalos project for the teaching of English (as a second language) to deaf and hearing impaired people through the use of Sign Language. Firstly, special educational e-content was developed using modern digital and animation technologies, which was divided into educational levels in accordance to the special needs of the deaf and hearing impaired students. In addition, this special educational content was embedded in a newly developed e-learning environment aiming at the distance training of the aforementioned target group. Apart from the educational material, special evaluation tests were embedded in the e-learning environment towards the assessment and evaluation of the skills of the students. Finally, an intelligent taxonomy system was used for setting the e-content to the right level as well as for the realization of the evaluation process. The procedure can be used in tertiary education.
