Recently, numerous authoring tools for Augmented Reality (AR) have been proposed, in both industry and academia, with the aim to enable non-expert users, without programming skills, scaffold educational AR activities. This is a promising approach that can democratize learning. However, there no systematic analysis of these emerging regarding what features modalities they offer (RQ1). Furthermor...

Didactic meta-programming is an answer to the need of rational introducing hypermedia, as part of information technologies, to didactic processes. A thorough analysis explaining the causes of traditional methods failures in a programmed training is needed to move beyond technological (equipment) school modernization expressed, at most, by well-equipped computer rooms with Internet access and mu...

The widespread availability of platforms for producing hyper-systems (i.e. hypertext and hypermedia) shows great potential for producing computer based learning environments. However, we do not yet have a great deal of experience in understanding how to make best use of the structural and media possibilities opened up by such systems. This paper explores the issues by analysing the techniques u...
