A review of studies on death awareness among children who are healthy, chronically ill, and terminally ill reveals that children with life-threatening diseases demonstrate increased understanding of death. In contrast, healthy and chronically ill children appear to require certain age, cognitive development level, or intelligence thresholds to…

Investigated preschoolers' responses to ambiguous descriptions of location. Ambiguous ("in one of the bags") descriptions caused longer search latencies in four- and five-year olds than nonambiguous descriptions ("in the bag by the chair"). The reverse was true for three-year olds. Results suggest that changes in information…

Distinguishes the values of quantitative increments and qualitative shifts with regard to problem solving. Subjects were 136 children ranging from 6 through 8 years and were presented with the standard 3-disc problem to resolve in 3 minutes. Results indicated that qualitative shifts in children's representation of problem space are a crucial…

Explains how teachers of students in grades four through six can use the Teaching Games for Understanding Approach and incorporate games invention into the physical education curriculum. A three-step model is proposed: selection and modification of games; teaching games with an understanding approach; and student invention of games. Summaries of…

Presents case study of a child trying to represent and understand the water wheel as an example of knowledge construction from the constructivism perspective. Focuses on how his understanding of physical perspective taking advances through conflicts in the use of different media (telling, drawing, paper, clay, or wood model) and how the Reggio…

Examines practice play, symbolic play, games with rules, and constructions and their relation to Piaget's active education, the intentional social process of constructing understanding involving interest, experimentation, and cooperation within the play context. Recommendations for identifying the type of knowledge being constructed (physical,…

Presents a way of interpreting mathematics classrooms, by advancing the notion of sociomathematical norms, to account for how students develop mathematical beliefs and values and how they become intellectually autonomous in mathematics. Includes episodes from a second-grade classroom to clarify the processes by which sociomathematical norms are…

Four-year olds, 6-year olds, and adults were given a computer-game mental rotation task, but with no instructions on mental rotation or other mental activity. Reaction time patterns and verbal reports revealed that 6-year olds were comparable to adults in spontaneous use and subjective awareness of mental rotation. Four-year olds who referred to…

Used short narratives to study false memory in 6-, 8-, and 11-year olds and adults. The persistence effect and false-memory creation effect were greatest for statements that would be regarded as factually incorrect reports of events in sworn testimony; like suggestive questioning, interviews that involve nonsuggestive recognition questions may…

Investigates the ways in which young adults make judgments about two contrasting kinds of rights: moral worthiness (the aretaic) and moral obligation (the deontic), reflecting on how thinking in these areas may be coordinated with responsibility judgments and behavior. Discusses what might be gained if the aretaic domain were taken into account in…

Analyzes the practices of two skilled and experienced middle level teachers with regard to research-based criteria for cognitive scaffolding in support of inquiry-oriented teaching. Research questions include: (1) what do skilled, experienced teachers do when scaffolding inquiry-oriented instruction; and (2) in what ways do they align with…

Two studies examined age differences in conditional reasoning. Results indicated that 8-year-olds performed better when antecedents were weakly associated with consequents than on strongly associated antecedent/consequents, with no difference among 11-year-olds. Eight-year-olds did better on ad hoc premises than on causal premises, with no…

Examined influence of object labels and shape similarity on 16- to 21-month-olds' inferences. Found that infants generalized non-obvious property of unlabeled objects to test objects with highly similar shapes. For objects labeled with novel nouns, infants relied on shape similarity and shared labels to generalize properties. For objects labeled…

Two experiments tested a model of young children's induction that specified contributions of linguistic labels and perceptual similarity to children's induction. Results support model predictions and point to a developmental shift, from treating linguistic labels as an attribute contributing to similarity to treating them as markers of a common…

Two experiments examined children's semantic representations and semantic naming errors. Results suggested that functional and physical properties are core aspects of object representations in the semantic lexicon and that the degree of semantic knowledge makes words more or less vulnerable to retrieval failure. Discussion focuses on the dynamic…
