What kind of influence does the structure of an educational hypermedia system have on the way its users understand its contents and organize the knowledge they acquire through its browsing?

In education, communication via semiotic systems forms an important role in guiding children toward the effective use of information and techniques, and it is important that…

This study documented the processes of knowledge construction and knowledge representation in high school students' hypermedia design projects. Analysis of knowledge construction in linking and structural building yielded distinct types and subtypes of hypermedia documents, which were characterized by four features of knowledge representation: (a)…

This paper focuses on issues of representation and interaction styles that are relevant considerations in the design and analysis of hypermedia learning environments. Analysis is supported by examples from the "HUGH" series of studies involving learners in reasoning about formal hypermedia representations. The representational issues include…
