It is demonstrated in this chapter that enhanced interactivity is the single most important reason why teachers should practice Web-based teaching and why students should be encouraged to construct Web-based learning communities. The notion of a conversational learning community (CLC) as a kind of constructivist learning environment is introduced. It is shown that instructional interactivity, d...

The aim of this research is to determine the degree of quality, stated in terms of interactivity and usability, of websites from Spanish franchises in the field of Optics and Optometry. For this purpose, all the existing bibliography was checked and the concept of interactivity and usability in websites was also defined. Besides, a series of indicators (Nielsen) were chosen which enabled us to ...

Almost every scholarly examination of the concept of interactivity to date has mentioned conceptualization difficulties (Rafaeli 1988; Moore 1989; Heeter 2000; Schultz 2000; McMillan 2002). This chapter is an attempt to proceed beyond complaints about ambiguity and overuse of the interactivity concept. Both theory and practice require a well-defined, clear and measurable definition for interact...

The concept of interactivity and its implications for Web-based learning system design is re-examined. The author reviews the literature on the interactivity concept from the perspectives of communication, computer-assisted instruction, distance education, and interactive dimensions and functions for Web systems. A proposal is then made for a technical framework for including such dimensions an...

Recently Web-Based Instruction (WBI) has been adopted for many educational systems in order to support distance education. WBI has become popular in that it overcomes time and space limitation in traditional educational systems. But due to lack of face-to-face communication, it is crucial that WBI provide interactivity and motivation for students. This paper introduces a formal model that evalu...

The Pragmatic Web is seen as a direction for realizing the vision of the Semantic Web. Realizing the vision of the Pragmatic Web, however, requires a shift in thinking about technology as a means for designing communication (which is making forms of interactivity possible that may otherwise be difficult or impossible). Some lessons from theory and research on Pragmatics provide grounds for unde...

Political parties and politicians increasingly use the possibilities of the Internet to communicate interactively with citizens and vice versa. The Internet also offers opportunities for individual politicians to profile themselves. These developments are often said to bring politics closer to citizens, increasing their political engagement in politics. Empirical evidence for such claims is, ho...
