A mathematical model of information acquisition is presented and empirically evaluated in comparison to evidence obtained from experimental studies of science content acquisition. Implications of the model for human information acquisition and future research are discussed in the context of the unique theoretical framework of the model. (Author/JN)

This paper examines how some fundamental mechanisms of nervous system activity can explain human information processing and the acquisition of knowledge and provides additional theoretical support for constructivist applications to science education reform. The implications for scientific epistemology and conceptual change processes in science…

In the literature, learners' cognitive development is mainly discussed with respect to changes in learners' content-dependent knowledge (conceptual change or growth). Additional dimensions of time and complexity may also be taken into account to describe cognitive processes in at least three dimensions. We discuss these three dimensions of…
