Canadian children follow an apparent sequence in the development of a concept of nationality from a verbal level of understanding of geographical relationships (beginning about age six), to an ability to demonstrate spatial relationships, then to an understanding of one's nationality, at about age 10. There are important educational implications.…

This study, conducted with seventh graders, lends support to the Piagetian hypothesis that the development of formal operations is a prerequisite for the effective learning of the proportions concept. (MK)

Investigated whether or not spatial relational concepts could be taught to preschool children. Specifically examined the relative effectiveness of movement-oriented vs. verbal visual-oriented spatial training programs. (Author/SB)

Presents several activities for helping kindergarten and first grade students develop an understanding of the main idea concept. (MM)

Examined whether children differentiate or confuse the domains of folk biology and folk psychology. Children and adult subjects were asked whether the animals depicted in pictures possessed certain biological and psychological properties. Results indicated that by kindergarten, notions of folk psychology and folk biology are sufficiently…

Three- and four-year olds were asked to recall their own or another person's actions and to acknowledge the false belief upon which the action was based. They showed excellent recall of inappropriate actions based on a false belief, but failed to use the recalled action as a clue to acknowledge the false belief upon which it was based. (TJQ)

Explores the dissociation between the performance by children with autism on false belief tasks, on which they do poorly, and false photograph, false map, and false drawing tasks, on which they do well. Suggesting domain specificity in the development of representational system, the results supported the modularity of theory of mind and the…

Describes the problem-solving behaviors of six novice subjects attempting to solve an electrostatics problem in calculus-based college physics. The level of qualitative thinking exhibited by these novices was determined. Sound procedural knowledge and problem representation were suggested as an integral part of skilled problem solving in physics.…

Twenty-three intermediate grade students (seven with learning difficulties) completed a concept mapping and vocabulary quiz, with instructions highlighting the value of learning goals or performance goals. Children with varying learning histories mediated in-school learning with qualitatively distinct epistemologies, and the "learning goals" task…

Seven infants and toddlers with severe/profound and multiple learning difficulties were presented with a contingency situation which they could control. Increased responses and positive emotional effects, which were reversed when their control was eliminated, suggested that infants with mental ages as young as two months can detect cause and…

Two experiments tested two, three, and four year olds' ability to understand false beliefs. Results of both experiments support earlier claims that an understanding of false beliefs and deceptive ploys emerges at around age four. Two and three year olds can be led to produce such ploys but show no clear understanding of their effect. (GLR)

Two inquiry-based teaching activities that are structured to cause cognitive disequilibrium and enable the student to alleviate the disequilibrium with the resultant equilibration at a higher cognitive level are presented. The first activity uses a Cartesian diver and the second a short film in which students are asked to determine the main idea…

Advocates an ideology stressing survival of the planet. Discusses major changes in the concept of war since the advent of nuclear warfare. Considers three stages for the development of peace: negative peace, nonviolence or conflict resolution, and positive peace. Reviews research on young children's capacity for understanding peace concepts. (AC)

A model of critical thinking is developed, encompassing problem solving and creative thinking. The central role of critical thinking in adult education is explored, concluding that development of the concept and how to teach it need attention. (SK)

The literature on how and when children acquire temporal concepts is reviewed in the context of the acquisition of time concepts by deaf children. The stages at which children acquire concepts of clock, calendar, historical time, and chronology, and effects of language acquisition are discussed. A more formal structure of temporal concepts in the…
