Dialogue act (DA) classification plays an important role in understanding, interpreting and modeling dialogue. Dialogue acts (DAs) represent the intended meaning of an utterance, which is associated with the illocutionary force (or the speaker's intention), such as greetings, questions, requests, statements, and agreements. In natural language…

Collaborative dialogue is rich in conscious and subconscious coordination behaviours between participants. This work explores collaborative learner dialogue through theories of alignment, analysing inter-partner movement and language use with respect to our hypotheses: that they interrelate, and that they form predictors of collaboration quality…

This study investigates the impact on L2 oral performance of participatory structure of strategic planning (individual vs. collaborative pair planning) and task complexity (simple vs. complex tasks) defined according to the number of elements involved. It also explores individual and collaborative planners' planning behaviours prior to simple vs.…

As language acquisition research supports the value of the interactive scaffolded environment and awareness-raising communicative tasks for the development of pragmatic knowledge, the present study attempted to investigate the effect of Collaborative Translation Task (CTT) on learning and retention of request speech act strategies. The main…

This article presents the SONAR project ("Subtitulación sOcial para proporcioNar Accesibilidad audiovisual en la univeRsidad" [SOcial subtitliNg to provide Audiovisual accessibility at the univeRsity]). Conducted to assess the validity of the creation of social subtitling networks, its ultimate goal is to better understand the role that…

In this paper, a review of the role of input, output and instruction in second language acquisition is provided. Several pedagogical interventions in grammar instruction (e.g., processing instruction, input enhancement, structured output and collaborative output tasks) are presented and their effectiveness reviewed. A final and overall evaluation…

Collaborative problem solving in computer-supported environments is of critical importance to the modern workforce. Coworkers or collaborators must be able to co-create and navigate a shared problem space using discourse and non-verbal cues. Analyzing this discourse can give insights into how consensus is reached and can estimate the depth of…

This study examined the effects of communication mode ("i.e.", face to face versus computer mediated communication) on the instances of negotiation of meaning (NofM) and its level of noticing by learners. Sixty-four participants (32 dyads) completed two jigsaw tasks in two different mediums (one in each) and four days after the tasks…

Collaborative output has been found to facilitate L2 lexical learning due to the cognitive word processing engendered in it. Yet it is not clear how interactions involved in collaborative output could affect learners' word processing and hence their lexical learning. This paper takes a sociocultural perspective to investigate Chinese EFL learners'…

Although teamwork has been identified as an essential skill for Computer Science (CS) graduates, these skills are identified as lacking by industry employers, which suggests a need for more proactive measures to teach and assess teamwork. In one CS course, students worked in teams to create a wiki solution to problem-based questions. Through a…
