The purpose of this article is to show how the philosophical theory of inferentialism can be used to understand students' conceptual development in the field of mathematics. Based on the works of philosophers such as Robert Brandom, an epistemological theory in mathematics education is presented that offers the opportunity to trace students'…

Children's worlds are increasingly populated by intelligent technologies. This has raised a number of questions about the ways in which technology can change children's ideas about important concepts, like what it means to be alive or smart. In this study, we examined the impact of experience with intelligent technologies on children's ideas about…

When children learn categories, they do not learn isolated facts but rather systems of knowledge. These systems of knowledge are composed of property-property (e.g., things with wings tend to have feathers), property-role (e.g., things with eyes tend to eat), and role-role (e.g., things that eat tend to sleep) correlations. Research has shown that…

Tests the distinction between inferring new categories on the basis of property information (predicted to be difficult) and inferring new properties on the basis of category information (predicted to be easier) among 57 preschool children. (HOD)

Investigated in 3 studies whether 2- to 4-year-olds make accurate causal inferences on the basis of patterns of variation and covariation. Found that all three age groups considered information from various patterns of variation and covariation in judgments regarding two objects and activation of a machine. Three- and 4-year-olds used the…

A constructionist theory is described that accounts for the knowledge-based inferences that are constructed when readers comprehend narrative text. Distinctive assumptions of the constructionist theory embrace a principle of search (or effort) after meaning. Literature in support of the theory is reviewed. (SLD)

Individual differences in same-aged children's reasoning about effort and ability, as well as the consequences of different forms of reasoning in actual achievement situations, were investigated. It was hypothesized that different forms of children's reasoning would be related to different (helpless versus mastery-oriented) motivational patterns.…

Describes three experiments that examined how children (4- to 11-year-olds) use their knowledge of the attributes of living things to infer whether particular objects are alive. (HOD)

Examined preschoolers' inductive inferences across biological and non-biological kinds. Found support for gradual-enrichment model of conceptual change. Four-year-olds had a limited, coherent, independent biological theory which may form the basis of mature understanding of biological kinds. Explored results in terms of multiple explanatory…

The present study investigates the development of children's ability to make inferences about a peer's mental state. In this study 48 eight-year-old children, 49 ten-year-old children and 44 adults observed and analyzed short video sequences, extracts from a socio-cognitive interaction between two children working on a mathematical task. The…

Describes two studies investigating the development of recursive thinking in 60 Dutch children five, seven, and nine years of age. The first study replicated earlier research employing a verbal production procedure. The second study used verbal comprehension procedures and concluded that development appears two years earlier than indicated by the…

Uses four children's explanations to illustrate their use of assimilation and inference in a butterfly life-cycle activity. Describes how interviewing young children about their understanding, and recording and reflecting upon their answers, can allow teachers to better understand how students process information and construct knowledge, and…

Describes the Chata Project, a British research project that challenged the prevalent assumption that children will construct sound causal explanations from factual information imparted during history instruction. Their research suggests that explicit instruction is required for children to understand the causal relationships among events,…

Compares inferences about story characters' behavior, perceptions, and goals made by eighth graders, eleventh graders, college freshmen, and college seniors. Concludes that from early adolescence to young adulthood, readers shift from conceptions of characters in terms of immediate surface feelings and behaviors to conceptions in terms of…
