Assign the students the appropriate task associated with this own capabilities and knowledge, and form rights groups among team members are two main problems that a Pedagogical Agent –acting like a trainermust solve into a Collaborative Virtual Environment for training. We use reusable learning objects design by contract to formulate a Student Knowledge Model and a student ZPD, concepts derived...

This paper sets out to present a novel construal of one of the notions of Vygotskian cultural-historical theory viz., zone of proximal development (ZPD) drawing upon dynamic systems theory. The principal thesis maintains that ZDP is an emergent and dynamic system which is engendered by a dialectical concatenation of psychogenesic and sociogenesic facets of human development over time. It is rea...

Dynamic assessment (DA) as an alternative to psychometric-based testing focuses on the collaborative dialogue between the learners and the mediator to move the learners from their current capabilities. This study represents a web-based qualitative inquiry in online DA which aims at addressing the inadequacy of the diagnostic feedback of the web-based DIALANG test in reflecting learners’ potenti...

The purpose of this study is to advance the notion scaffolding in coaching as a socio-pedagogic activity through exploring “doing” during competition preparation period. Using method critical companionship, analysis draws on storied representation coach’s practice. Findings conceptualise transformative process continuous building and enacting both coach athlete’s agentic capabilities enhance le...

AbstractPinching and dormancy breaking chemicals (DBC) application are potentially used to regulate the growth of plant. This study aims evaluate response ‘Crystal’ guava (Psidium guajava L.) seedling in pinching DBC application. experiment was carried out Integrated Field Laboratory, Faculty Agriculture, Universitas Lampung from March June 2021, with a randomized completely block design (RCBD)...

BACKGROUND/AIMS To observe the effects of vitrification on spindle, zona pellucida, embryonic aneuploidy and DNA injury in in vivo-maruted, in vitro-mature and immature human oocytes. METHODS Between January 2009 and February 2015, 223 immature oocytes from 450 infertile patients, and 31 in vivo-mature oocytes from 3 infertile couples were collected. Of the 223 immature oocytes, 113 were used...

The Ecolab is an interactive learning environment constructed with the aim of providing a tool to investigate how software can offer help and support to an individual learner. The design framework is informed by Vygotsky's Zone of Proximal Development (ZPD) and previous work on face to face tutorial assistance. Three Ecolab versions implement different variations and combinations of design feat...
