We investigated second and third graders' capacity to understand microevolution, given a learning progression leveraging intuitions to build more adequate explanations, problematizing core ideas within scientific practices, and in-depth study of a single domain (botany or animal behavior). The intervention was implemented in both researcher-taught…

Scientific reasoning abilities are already developing in elementary-school-aged children and enable them to understand the world around them. The goal of the current study was to develop a new instrument for 8- to 10-year-old children in Grades 3 and 4 to measure their understanding of the steps of the "scientific inquiry cycle" (SIC).…

As classrooms continue to diversify, there is an increasing need to understand children's inclusive behaviours and moral reasoning. Research shows that epistemic beliefs (beliefs about knowing and knowledge) can influence reasoning for adults, but we know little about this relationship in younger children or how classroom contexts relate to…

Research on scientific reasoning plays an essential role at the intersection of cognitive development and science education. As only few paper-pencil-tests exist to assess scientific reasoning abilities of elementary school children, the goal of the current study was the development of a new reliable and valid instrument. We focused on the…

Examined the developmental sequence through which adolescents progress in solving a physics problem (balance beam ratio and proportion) and a social problem (predicting the behavior of a story character). Although most of the 9- through 19-year-olds performed at predictable and similar developmental stages on each task, a minority were more…
