Preschool children’s basic scientific reasoning abilities were investigated in two experiments. Consistent with findings by , Experiment 1 showed that even 4-year-olds can evaluate patterns of covariation evidence. However, even 6-...

Three experiments considered how the positive or negative framing of decisions affects children’s EV (expected value) judgements and choices. In Experiment 1, 6- and 9-year-olds chose between a sure gain and a gamble or between a sure loss and a gamble, ...

Research on conceptual development in the domain of biology shows that young children with normal development are familiar with basic concepts but not yet with causal biological processes. Do children with lower IQ acquire the same knowledge at the same ...

According to the theory of representational redescription (RR theory, ), children’s reasoning is grounded on implicit knowledge. This initial knowledge is first consolidated and then subjected to reiterative cycles of representational ...

Young children erroneously believe that differences either in mass alone or in volume alone can predict differences in sinking speed. The current study was an attempt to teach preschool children that neither mass nor volume alone is predictive for sinking ...

In a study with 56 third-graders, we tested whether reasoning with line graphs can be enhanced by representational activities within a curriculum on floating and sinking of objects in water. We hypothesized that representing mass and volume on the ...
