The process of change represents a main, central issue for the study of development. Basic and applied researchers in developmental science have aimed their research work at answering several key questions related to the problem of change. How does change occur? What mechanisms produce change? What conditions are likely to promote the emergence of change in development? Another related question...

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...

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 expe...

The theoretical approach of microgenesis, or process-theory more generally, is gaining new adherents in neuropsychology and cognitive psychology, while its initial formulation and gr...
