Elearning Content ‘Usability’: Semiotic and Didactic Parameters in Digital Texts and Textuality

AbstractThe paper deals with the notions of e-learning content digital texts and digital textuality as design guidelines for the development of didactic materials in the light of semiotic and psycholinguistic approaches. A typology of didactic texts/goals and the cohesive relation between language and visual components in didactic tutorials as far as perception, comprehension and finalization of content will be dealt with.The semiotic and didactic assumptions will be theoretically illustrated and discussed through the analysis of a number of online demo referring to maths, medicine, and economic sciences presentations.Conclusions on the need for design implementation of e-learning content will be summed up through a specific checklist of semiotic and pedagogical features for e-content development
