The discussion on the dynamic assessment (DA) -- a combination of assessment and instruction -- and regulatory scales from implicit to explicit corrective feedback (CF) is relatively new in the CALL context. Applying the notions of Sociocultural Theory, Zone of Proximal Development (ZPD) and Mediation, the present study examines how a DA-based…

Text chat facilitates L2 use by providing learners with extended time to plan, monitor, and process production during interactional tasks. However, learners may not naturally take advantage of these affordances, especially for providing peer feedback. This study used video-enhanced chat scripts to examine the behavior of beginner L2 Spanish…

Previous studies on web-based collaborative writing have shown that task modality impacts peer interaction patterns and attention to form. However, these studies have primarily focused on contrasting a face-to-face oral condition with a text-based synchronous computer-mediated communication (SCMC) environment. Few studies have compared peer…

This review discusses and compares the findings of 38 peer-reviewed studies on text-based synchronous computer-mediated communication for second or foreign language learning from over the past twelve years. Research themes that emerged include: modality, corrective feedback, noticing, alignment and uptake, as well as task design/conditions and…

The role of recasts, a corrective feedback technique, has received much attention from instructed SLA researchers. While a variety of factors have been identified as influencing their effectiveness in facilitating uptake and L2 development (e.g., learners' age and level of proficiency), the role of mode of interaction has been the object of…

This dissertation reports on the evaluation of a computer-mediated collaborative animation description task, where synchronous corrective feedback (SCF) serves as the primary source for grammar learning. The evaluation was conducted in an English-as-a-Second-Language (ESL) writing program at a large research university in the United States. Using…

Despite suggestions being a common speech act used by writing center tutors, very limited research is available on the use of suggestions in online writing center practice. Drawing upon multiple sources of data including the chat transcript, screen recording of the session, and final revised version of the writer's text, this case study explores…

Recent discussions in language communication indicate the effectiveness of technology and computer-mediated communication. Research also highlights the central role of synchronous and asynchronous modes of interaction in second and foreign language development. Gaining insights from Vygotskyan sociocultural theory of mind, the present study…

This study investigated the effects of corrective feedback (CF) during in-class computer-mediated collaborative writing on grammatical accuracy in a new piece of individual writing. Forty-eight ESL students at an American university worked on two computer-mediated animation description tasks in pairs. The experimental group received indirect CF on…

The benefits of corrective feedback (CF) for second language (L2) learning are empirically attested, and multiple factors mediating CF effectiveness have been investigated. However, the timing of oral CF has received less attention given most research examines corrections provided immediately after an error. Delayed CF also warrants investigation;…

Multiple theoretical frameworks support the notion of interactional feedback as facilitative of second language (L2) development. However, research demonstrates that learners often avoid providing feedback during peer collaborative work, thus failing to take advantage of key opportunities for language learning and development. Recent studies have…

Theoretically emerged from Vygotsky's sociocultural theory of mind (SCT), Dynamic Assessment (DA) highlights the notions of mediation and reciprocity as the dynamics of learners' progress toward independent functioning. As a qualitative inquiry into the nature of Iranian EFL learners' development in DA based academic writing courses, this study…

In face-to-face conversations, speaker transitions (or hand-offs) are typically seamless. In computer-mediated communication settings, speaker hand-offs can be a bit more challenging. This paper presents the results of a study of audio communication problems that occur in an online synchronous course, and how, and by whom, those problems are…

This study investigated the role of corrective feedback timing in the acquisition of Spanish noun--adjective gender agreement. Forty-five learners completed a communicative task via synchronous computer-mediated communication (SCMC) in one of three groups (immediate, delayed, control). The immediate-feedback group received error reformulations…

In technology-enhanced language learning, many pedagogical activities involve students in online discussion such as synchronous chat, in order to help them practice their language skills. Besides developing the language competency of students, it is also crucial to nurture their teamwork competencies for today's global and complex environment.…
