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 present study aimed at investigating the possible impact ofZone of Proximal Development (ZPD) on the learners’ performance. Forty-sixIranian university students participated in this study by taking two types of readingcomprehension tests (i.e., the main idea and Wh-question type). The researchersused the Winstep program to analyze the data and estimate the learners’ Raschmeasure in pre, pos...

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 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...

group dynamic assessment (g-da) grounded in vygotsky’s socio-cultural theory (sct) is believed to have the potential to provide a context for capturing a group of learners’ zone of proximal development (zpd) (poehner & lantolf, 2010; shabani, 2010). the present study aims at testing the applicability of g-da in identifying the mediational strategies offered by a mediator during his g-da int...

Most recently, the Flipped Classroom model has drawn the attention of many educators as an effective means of organizing and developing individual competencies. The goal in the university setting at Grand Valley State University, College of Business (GVSU) is to improve cognitive practice and increase learning in the value creation process and the zone of proximal development (ZPD) environment....

One of the theories accounting for pragmatic development of L2 learners is Vygotsky’s (1978) sociocultural  theory.  This  study  investigated  the  development  of  EFL  learners'  pragmatic competence through the lens of an important concept of Vygotsky’s theory, i.e.  the  zone  of proximal  development.  The  study  was  conducted  to  answer  two  questions.  The  first  question was wheth...
