This article is a conceptual and methodological exploration of a new construct, task interactional difficulty, and of a possible approach to assessing task demands in general. After arguing for the use of 'task difficulty' instead of 'task complexity', the notion of task interactional difficulty is analyzed, first by reviewing previous SLA…

Languages spoken in larger populations are relatively simple. A possible explanation for this is that languages with a greater number of speakers tend to also be those with higher proportions of non-native speakers, who may simplify language during learning. We assess this explanation for the negative correlation between population size and…

This dissertation uses conversation analysis to examine three non-disagreeing functions of the token "no" when it prefaces a turn at talk. In the first function, "no"-prefaces index and respond to an inferential component of a prior turn. This practice entails a number of sub-practices, in which speakers use…

Research on the linguistic characteristics of university classroom discourse highlights the salience, in this register, of non-informational and subjective aspects of discourse. This dimension of classroom discourse, however, has not been studied systematically. Taking a corpus-based approach, this study investigates the non-informational…

This dissertation takes an ethnomethodologically-grounded, conversation-analytic approach in investigating the sequential deployment of linguistic resources in Spanish-language talk-in-interaction. Three sets of resources are examined: 2nd-person singular reference forms (tú, vos, usted), indicative/subjunctive verbal mood selection, and…

This dissertation uses conversation analysis as a theoretical and methodological framework to examine the organization of in-house business meetings that are conducted in Japanese. In particular, this study focuses on how institutionality becomes apparent within the participants' interactions. The data consists of six videotaped in-house…

This dissertation explores co-construction of a situated activity in a current unit by mainly focusing on hearers' actions. The "co-construction" involves a process of interaction in which speakers and hearers jointly construct the form and the meaning of ongoing utterances even when they disagree with each other (Jacoby & Ochs,…

This study investigates the dynamics in the Spanish classroom between heritage language learner (HLL) dyads, second language learner (L2L) dyads, and mixed HLL-L2L dyads. Specifically, it examines oral, written and embodied discourse that informs our understanding of how learners attend to language. Analysis for this dissertation examined…

The premise of this paper is that the interactional practices constituting teacher-student interaction and language learning are interdependent in that the substance of learners' language knowledge is inextricably tied to their extended involvement in the regularly occurring interactional practices constituting their specific contexts of learning.…

New trends in language teaching have resulted in a move towards research in the language classroom. A brief overview of classroom research reveals three distinct but inter-related research paradigms: classroom-centered research, classroom process research, and qualitative research, respectively.
