This microgenetic study strived to understand instantaneous peer influences on the moment-bymoment and session-by-session development of relational thinking within and across dialogic smallgroup discussions using an approach called Collaborative Reasoning. An analysis encompassing 32,511 turns for speaking during 176 discussions indicated that peer support and refutation influenced the developm...

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...

We examined short-term changes in children’s numerical estimation, the representational changes that gave rise to improved estimates, and the hypothesis that experiences that highlight discrepancies between logarithmic and linear representations of numerical magnitude result in the greatest changes in estimation accuracy.

To examine patterns of strategy choice and discovery during problem-solving of a novel locomotor task, 13.5- and 18-month-old infants were placed at the top of a staircase and encouraged to descend. Spontaneous stair descent strategy choices were documented step by step and trial by trial to provide a microgenetic account of problem-solving in action. Younger infants tended to begin each trial ...

The present study is an attempt to shed light on the effect of Dynamic Assessment (DA) on diagnosing and developing the receptive vocabulary abilities of upper-intermediate learners learning English as a foreign language. Fifty L2 leaners participated in the First Certificate in English test and completed Vocabulary Knowledge Scale. Out of 50 students, ten learners who were identified as being ...

Summary writing is associated with lots of cognitive and metacognitive complexities that necessitates instruction (Hirvela & Du, 2013). Contrary to majority of studies carried out on summarization instruction, the present study addressed the underlying processes or microgenetic developments of the Iranian EFL learners’ summary writing. To this end, 41 male and female undergraduate students rece...

The authors used microgenetic methods in 2 experiments to examine children's and adults' progress from initial attempts at spelling nonwords to later direct memory retrieval of the spellings. Participants repeatedly spelled nonwords presented in computerized, dictated-word spelling tests over several weeks. Following each spelling, participants provided retrospective strategy reports. Half of t...

Children confront the formidable task of assimilating information in the environment and accommodating their cognitive structures to that information. Developmental science is concerned equally with two distinctive features of these processes: children's group mean level of performance through time and the standing of individual children through time. Prevailing opinion since the inception of t...
