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...

testing as a general trait of social life has received a great deal of attention by many language teachers and scholars. throughout history, people have been tested to prove their abilities and experiences or to confirm their capacities. many authorities have said that assessment and instruction should be integrated as a single and inseparable activity which seeks to understand development by a...

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...

originating from vygotsky’s sociocultural theory, dynamic assessment (da) proposes a novel approach to second language acquisition (sla) research according to which a dialectical relationship is envisaged between instruction and assessment. although da has been applied to some areas of sla, there are areas, such as interlanguage pragmatics (ilp), that have been neglected.  to address the issue,...

evidence acquisition a search of pubmed for studies on proximal fifth metatarsal fracture and jones fracture focusing on the classification and management was performed. the reference list of the retrieved articles was searched for additional related studies. conclusions lawrence and botte’s classification of proximal fifth metatarsal fractures is recommended by experts, due to its implication ...

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...
