this study examined the effect of the zpd-based discourse scaffolding on efl learners' co-construction of l2 metadiscourse performing collaborative writing tasks and explored the discourse scaffolding dynamics. the participants were 160 efl students that were assigned to four different treatment conditions: (i) formal teaching, (ii) input enhancement, (iii) non-zpd interaction, and (iv) zpd-bas...

The present article describes how scaffolding is implemented in an intelligent tutorial system call NTUs (Number Transcoding tUtorial System), and what are the results of the system tested empirically on a group of grade students in fostering their number concepts. To use NTUs. the system first analyzes a user’s errors on a number transcoding task, and the results of analysis are used to infer ...

The application of zone of proximal development (ZPD), as a major tenet of Vygotsky’s sociocultural theory (SCT, 1978), has recently been invited in the L2 learning/teaching profession. This study mainly examined whether Iranian EFL learners’ interactions in diverse ZPD-activated proximal contexts through the use of storytelling instruction could improve their oral (speaking) proficiency and at...

For decades, Vygotsky’s Zone of Proximal Development (ZPD) has been utilized as an important theoretical framework for exploring and analysing the concept learning, but its implications teachers remain much less explored. In this article, I conceptualise some roots sociocultural theory learning and, on basis, explore ZPD ethical powerful zone teaching. Together with providing a thorough descrip...

central to vygotsky-inspired sociocultural theory (sct) is the notion of zpd seen by sla researchers as a useful framework within which l2 teaching and learning can take place. van lier (2004) argues that the zpd could be activated in diverse proximal contexts (pcs) and is not limited to the expert-novice scenario. . this study probed whether iranian efl learners' collaborative task performance...

This study represents an effort to construct a learning framework for knowledge building and collective wisdom advancement in a virtual learning community (VLC) from the perspectives of system wholeness, intelligence wholeness and dynamics, learning models, and knowledge management. It also tries to construct the zone of proximal development (ZPD) of VLCs based on the combination of Vygotsky’s ...

The paper reviews the research on use of Dynamic Assessment (DA) in language classroom instruction for group learners. DA assesses learners’ abilities a comprehensive scope Zone Proximal Development (ZPD) from one continuum actual independent performance to other potential with external support, and also sees support offered as driving force advancing development within ZPD. With its unique vie...
