Sequencing Learning Objects: Space-time, Semiotic and Pedagogical Constraints

摘要

A Learning Object composition model based on semiotic aspects of narrative is proposed with the specification of space, time and semiotic constraints. Learning objects are considered as signs, since they convey meaning through a physical support. Space, time, semiotic and pedagogical requirements are addressed to satisfy constraints in order to prevent overlapping medias so that the cognitive load can be reduced.
