Critical Discourse Analysis (CDA) could be seen as a theory in qualitative more than in qualitative stud- ies. This might have led to difficulty in doing CDA. Accordingly, this study attempted to develop a quan- titative profile in the form of an analytic rubric. For this purpose, Fairclough’s model of CDA was select- ed as the research framework. The techniques used for structuring analy...

Navigation is a limited metaphor for hypermedia and website use that potentially constrains our understanding of human-computer interaction. In the present paper we trace the emergence of the navigation metaphor and the empirical analysis of navigation measures in usability evaluation before suggesting an alternative concept to consider: shape. The shape concept affords, we argue, a richer anal...

The paper is devoted to an approach to analytic tableaux for propositional logic, but can be successfully extended to other logics. The distinguishing features of the presented approach are: (i) a precise set-theoretical description of tableau method; (ii) a notion of tableau consequence relation is defined without help of a notion of tableau, in our universe of discourse the basic notion is a ...

Discourse analysis is increasingly becoming a methodology of preference amongst qualitative researchers. There is a danger, however, of it being viewed as a bounded and uncontested domain of research practice. As discourse analysis is inextricably linked with theoretical issues, it is a dynamic practice that is constantly in a process of revision. In this paper I reflect on some of the conceptu...

The first aim of this study was to contribute to a growing body of research in teacher-student classroom discourse, by describing, in detail, the discourse “moves” of a teacher during science conversations. Our second aim was to develop an enriched analytic framework that can account for the context, the content and the purpose of the discourse moves identified, arguing for a shift of attention...
