Truth claims in political discourse are implicated in a dialogic process whereby political actors "assimilate, rework, and re-accentuate" prior discourse (Bakhtin 1986:89). While political actors themselves may view truth as an object to be discovered, I argue that discourse analysts are best served by viewing truth as an emergent property of this dialogic process. In this paper, I examine how ...

In this paper we argue that a clear division between two sources of information— one oriented to world knowledge, the other to linguistic semantics—offers a framework within which mechanisms for modelling the highly flexible relation between language and interpretation necessary for natural discourse can be specified and empirically validated. Moreover, importing techniques and results from for...

Critical discourse analysis (CDA) has become a widely used academic research method in the social, political, educational, and linguistic sciences. This paper aims to explain how teacher-student dialogic is presented evaluated differently persuade students. Van Dijk's (2004) framework, identify discursive structures that lead ideologically based parochial, context, ideology, social cognition. T...

It has previously been shown that the effective use of dialogic instruction has a positive impact on student achievement. In this study, we investigate whether linguistic features used to classify properties of classroom discourse generalize across different subpopulations. Results showed that the machine learned models perform equally well when trained and validated on different subpopulations...

Learning from dialogues is a powerful pedagogy. Video-based and dialogic learning have become increasingly commonplace over the last decade and gradually evolve as one of the most popular teaching & learning strategies for modern e-learning (i.e. MOOCs). Identifying high-quality video dialogues is increasingly challenging because of the sheer number of video discussions being produced daily. In...

Question-answer (Q&A) is fundamental for dialogic instruction, an important pedagogical technique based on the free exchange of ideas and open-ended discussion. Automatically detecting Q&A is key to providing teachers with feedback on appropriate use of dialogic instructional strategies. In line with this, this paper studies the possibility of automatically detecting segments of Q&A in live cla...

We present a machine learning model that uses particular attributes of individual questions asked by teachers and students to predict two properties of classroom discourse that have previously been linked to improved student achievement. These properties, uptake and authenticity, have previously been studied by using trained observers to live-code classroom instruction. As a first-step in autom...

Title of Dissertation: SIMPLE REGRETS: COUNTERFACTUALS AND THE DIALOGIC MIND Jennifer Riddle Harding, Doctor of Philosophy, 2004 Dissertation Directed By: Professor Mark Turner Department of English Counterfactuals, or unrealized scenarios, have been a focus of research in an array of disciplines, though their rhetorical implications have gone largely unexplored. This interdisciplinary study us...

Since the early 1980s, composition studies has arrived at a broad consensus that it is important to understand how social contexts relate to the cognitive processes and individual behaviors involved in writing and reading texts, although within this broad consensus are various notions of context and of how contexts relate to processes and texts. Drawing on both structuralist and everyday accoun...
