Text complexity in elementary classrooms is typically measured by traditional readability tools, which rely on surface-level measures of word and sentence complexity. Theoretical and empirical work on text complexity, however, indicates that additional measures of semantics, syntax, and discourse structure may be equally important for…

What makes a discourse coherent? One potential factor has been discussed in the linguistic literature in terms of a Question under Discussion (QUD). This approach claims that discourse proceeds by continually raising explicit or implicit questions, viewed as sets of alternatives, or competing descriptions of the world. If the interlocutor accepts…

Background: Disorganized speech, manifested as derailment, tangentiality, incoherence and loss of goal, occurs commonly in schizophrenia. Studies of language processing have demonstrated that semantic activation in schizophrenia is often disordered and, moreover, the ability to use contextual cues is impaired. Aims: To reconstruct the origins and…

Analysis of interaction patterns is one of the most important indicators of quality of learning in educational web forums. Social network analysis (SNA) is gradually assuming importance in the study of interaction patterns as it focuses on the analysis of the interrelationships between individuals, thus providing a holistic perspective on group…

Numerous studies have affirmed the value of asynchronous online communication as a learning resource. Several investigations, however, have indicated that discussions in asynchronous environments are often neither interactive nor coherent. The research reported sought to develop an enhanced understanding of interactional coherence, argumentation,…

This study explores the ways in which academic writers employ expressions of attitude in the construction of evaluative stance in the introductory sections of research papers. The study draws on the theoretical base of Systemic Functional Linguistics (SFL) (Halliday, 1994, Halliday & Matthiessen, 2004), and in particular on Appraisal theory as a…
