My major interest is
development of perception and learning, from infancy to adulthood. In adult category learning different learning
processes have been distinguished, such as rational learning (forming explicit,
rule-based representations) and associative learning (forming exemplar-based
representations). How do different learning mechanisms develop from infancy
into adolescence? An important focus of my research is the measurement issue:
how can we detect different learning mechanisms in a reliable way such that we
account for possible individual differences. I apply statistical, latent
variable techniques to account for inter-individual differences (within the
same age group different children show different learning processes) and
intra-individual differences (within the course of one learning task, the
learning process may change). I study science learning as a specific context.
Also in science learning, people acquire different types of knowledge, implicit
and explicit knowledge. We study learning processes in a broad sense, including
curiosity, exploration, causal reasoning, mental models, conceptual change, and interest
development.
Current projects concern: causal reasoning and exploration
(in formal and informal settings), perceptual development in infancy,
development of rule-use in toddlers, computational models of learning,
mathematical models of learning, development of na?ve theories, adaptive
teaching strategies, comparative analysis of learning processes, interest
development as a network structure.
Recently, at the Vrije Universiteit Amsterdam, in a joint program with the UvA and University Leiden, we started the first Educational Master for Primary Education (EMPO) , to train for primary school teacher at a university master level.
