Proportional reasoning is one part of mathematics that is particularly hard to apprehend for children. At the same time, research suggests that already at an early age children develop an ability to make sense of some proportional situations. Previous research has shown that language – be it language in general or language related to mathematics – plays a crucial role in mathematical thinking and learning. The domain of proportional reasoning ...

The nature of the arithmetic word problems found in maths textbooksinfluences the way students develop their ability to solvethem, as teachers use the books in their classes quite frequently.Given that students are better able to reason through and solveauthentic problems that are contextualized in situations familiar tothem, and that different international assessments have shown thestudents in Singapore to be more skilled at problem-solving ...

Selecting a large and diverse sample of 5–6-year-old preschool children (179 boys and 174 girls; Mage = 70.03 months, SDage = 3.43), we aimed to extend previous findings on variability in children’s home math environment (i.e., home math activities, parental expectations, and attitudes) and its association with children’s mathematical skills. We operationalized mathematics in a broader way than in previous studies, by considering not only ...

Young children, students, and adults may have alternative ideas about the motion of the Sun and stars as we observe them in the sky. However, a good understanding of this apparent motion is essential as a startingpoint to study more advanced astronomical concepts, especially when these include astronomical observations. In this paper, we describe the development and validation of the apparent motion of Sun and stars (AMoSS) test, which can ...
