Compared reading and mathematics competencies of children with poor arithmetic fact mastery at the end of third grade to those of grade-level peers with good arithmetic fact mastery. Found that children with poor fact mastery showed little growth on timed number facts across second and third grades, despite normal growth in other mathematics…

Presents evidence that the supposed paradox in which infants find abstract patterns in speech-like stimuli whereas even some preschoolers struggle to find abstract syntactic patterns within meaningful language is no paradox. Asserts that all research evidence shows that young children's syntactic constructions become abstract in a piecemeal…

Asserts that the posited paradox between infancy and toddlerhood language was not eliminated by Tomasello and Akhtar's appeal to infants' robust statistical learning abilities. Maintains that scrutiny of their studies supports the resolution that abstracting linguistic form is easy for infants and that toddlers find it difficult to integrate…

Argues the main deficiency of the Lawrence Kohlberg theory is that it has never lived up to the claim of being a structural developmental theory. Explains that the theory has never shown specific problems at each stage. Ends with a discussion of a new stairway for Kohlbergian theory. (CAJ)

Examined the development of teaching skills in older siblings responsible for teaching their younger siblings to become competent members of their culture among children from a Zinacantec Maya village in Chiapas, Mexico. Found that by age 4, children took responsibility for initiating teaching situations with their younger siblings, and by 8,…

Two studies examined whether infants' category discrimination in an object-examination task was based solely on an ad hoc analysis of perceptual similarities among the experimental stimuli. Findings indicated that 10- to 11-month- olds' responses varied systematically only with the presence of a category change, but not with the degree of…

Describes an approach to the teaching of electricity that uses box and AVOW diagrams, novel representations of the properties of the electric circuit that portray current, voltage, resistance, and power. The diagrams were developed as aids in learning, understanding, and problem solving and to promote conceptual change by challenging a number of…

Two studies assessed the gaze following of 12-, 14-, and 18-month-olds. Findings indicated that infants at all ages looked at the adult's target more when the adult turned to the target with open eyes than when the adult turned with closed eyes. Additional evidence suggested that infants were not simply responding to adult head turning, but were…

Examined preschoolers' performance on false belief tasks and perceptions of parental discipline. Found that children performed better on questions about their own false beliefs than on questions about others' false beliefs. Overall, children performed below average on false belief measures; and children expected parents in hypothetical scenarios…

Examines the effects of using a conflict map on 8th grade students' conceptual change and ideational networks about simple series electric circuits. Analyzes student interview data through a flow map method. Shows that the use of conflict maps could help students construct greater, richer, and more integrated ideational networks about electric…

Collected qualitative data through interviews and triad elicitation with 5-year-olds in London to determine children's current knowledge and understanding of their "making" activity and of Lego construction kit components. Data provided triangulation for another study that found that young children could achieve a great deal with…

Discusses ideas from Vygotsky, Leont'ev and Bakhtin to show how fantasy play acts as its own zone of proximal development that contributes to the development of symbolic mediation, the appropriation of social roles and symbols, and the preschool child's preparation for elementary school. (JPB)

Two experiments examined the communicative bases of preschoolers' object appearance-reality (AR) errors. Found that AR performance correlated positively with performance on a control test with the same discourse structure but nondeceptive stimuli, and on a naming test. Overall findings indicated that the discourse structure of AR tests elicits a…

A study examined the basis of "theory of mind" (ToM) reasoning in 20 native signers (ages 4-8) of British Sign Language. Children and their siblings were given a measure of the quality of sibling relations. Sibling quality as perceived by siblings predicted children's ToM score over age and referential communication. (Contains…

Examined children's, adolescents', and college students' judgments of children's and adults' rights to freedom of speech and religion in societal, school, and family contexts. Found that endorsements of these freedoms were increasingly affected by social context and agent with age. College students were less likely than others to affirm children's…
