The current paper examines the instructional implications of Vygotsky's (1978) seminal notion of Zone of Proximal Development, originally developed to account for the learning potential of children, and investigates ZPD applications to the concept of teacher professional development. Specific attempt has been made to see how a number of assets at the teacher's disposal namely diary writing, pee...

Intelligent tutoring Systems (ITSs) adapt content and activities with the goals of being both effective and efficient instructional environments. They have goals for students to be challenged and guided in an optimal way--without being too overwhelmed with difficult material or too bored with easy or repetitive material. We propose a particular definition of the zone of proximal development (ZP...

This paper presented an in-progress research model to develop, design and test an innovated acculturated adaptive web-based learning systems which based on Vygotsky' s zone of proximal development (ZPD) development theory. Based on ZPD related theories and researches, this research proposed to use cognitive apprenticeship instruction model as design guides to develop the activity functions to s...

Purpose: To apply educational models of the Zone of Proximal Development (ZPD) and approaches to assisted performance to existing knowledge about surgical skill acquisition, and thus provide a framework for potentially enhancing surgical education. Summary: The stages of the ZPD appear to be consistent with existing psychomotor theories of skill acquisition. The fourth phase of the ZPD, where t...

Complex domain calibration is an efficient method to correct the amplitude and phase of a spectrum obtained from a Fourier transform spectrometer. This method is, however, not directly applicable in the occurrence of a zero path difference (ZPD) shift between a scene interferogram and calibration blackbody interferograms. This situation is likely to happen for a system with thermal instabilitie...

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...

An analysis of the influence of motivation on the ZPD is being carried out. To investigate the impact of motivational factors on the ZPD the inclusion of a motivation differentiator layer into the Ecolab [11] is proposed. The mechanisms and values to measure the motivational states of the learners and scaffold the motivational strategies to adjust them to individual pupils are outlined. The mai...

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...
