A central tenet of constructivist models of conceptual development is that children's initial conceptual level constrains how they make sense of new evidence and thus whether exposure to evidence will prompt conceptual change. Yet little experimental evidence directly examines this claim for the case of sustained, fundamental conceptual achievements. The present study combined scaling and exper...

A design that included both microgenetic and cross-sectional components was used to examine 135 Slovenian children's acquisition of matrix completion proficiency and compare microgenetic and age-related changes on the task. The microgenetic analyses indicated that children's errors became increasingly variable shortly before they discovered the correct strategy, that the correct strategy became...

Microgenetic  method  is  a  specific  method  for  studying  change  in  abilities,  knowledge,  and understanding  during  short  time  spans,  through  dense  observations,  and  over  a  relatively  long period of time. In this paper I will attempt to provide a brief overview of microgenetic method and will point out its potential advantages and disadvantages in the context of second langua...

Educational Data Mining (EDM) methods can expand the reach of microgenetic research. This paper presents an example of our pilot work using microgenetic analysis in the context of fraction game data, where we characterize student activity based on clustered sequences of actions. We cluster sequences by the similarity between them, calculated using optimal matching techniques.

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...

This publication is composed of three interviews conducted with Jason W. Brown a few years ago. The first is concerned with early influences that shaped his development of a theory of “microgenesis”. The second focuses on evolutionary principles apparent in brain development and mental processes. In the third interview, Brown discusses the internal processual structure of the “mind/brain state”...

The purpose of this study is to investigate the viability of a computer-based system for collecting and analyzing data from large-N microgenetic studies of scientific reasoning. Most studies of children’s scientific problem-solving strategies take place in classroom settings with established norms that homogenize student behavior. Small sample sizes and the limited range of settings limit the g...
