The study of 281 adolescents found no significant differences in creativity subvariables between the developmental stages of concrete and formal operations. Significant relationships were found between age and creativity. Figural flexibility, originality, and elaboration decreased as age increased from 13 to 16 years. (Author/JDD)

The goal of this research synthesis is to evaluate the validity of the claim that there are fundamental limitations on the ability of adolescents to engage in critical thinking. Critical thinking is defined as an analytic, focused cognitive activity aimed at understanding phenomena at a root rather than a superficial level; a type of thinking…

Proposes a theoretical model of cognitive development and applies this model to the secondary analysis of two large-scale studies which focus on the acquisition of formal operational schemata by adolescents in the United States and Israel. Results support the "unity" hypothesis of cognitive development that the various schemata of formal…

In one of his latest works, Piaget (1980) describes the course of development as alternating between periods of relative equilibrium, in which thinking is deductive and discursive, and periods of equilibration, in which thinking is dialectical and constructive. Progressive change depends on these dialectical periods, during which the construction…

One of the most challenging daily experiences of teaching young adolescents is helping them transition from Piaget's concrete to the formal operational stage of cognitive development during the middle school years. Students who have reached formal operations can design and test hypotheses, engage in deductive reasoning, use flexible thinking,…

The constructivist hypothesis that the acquisition of domain-specific conceptual knowledge (declarative) requires the use of general procedural knowledge was tested. Students (n=314) were classified as reflective, transitional, or intuitive thinkers and presented with four concept-acquisition tasks. Skill in hypothetico-deductive reasoning…

Administered five Piagetian tests to 180 adolescents for comparison to similar samples from 1967 and 1972. Found that today's adolescents exhibited higher levels of cognitive development than did previous cohorts. Gain varied across tasks, being very large for combinatory thought but mixed for conservation. This acceleration of cognitive…

To evaluate the part that nascent skeptical doubt plays in shaping adolescent social-cognitive development, 61 high school students clearly classified as in concrete or formal operational stages of cognitive development completed a measure of epistemic stances. A relationship was found between cognitive and epistemic development. (SLD)

Considers the period of adolescence and describes how cognitive-developmental concerns might apply to the understanding of adolescent problems in interpersonal and affective adaptation. Also investigates ways in which intervention practices with adolescents might be placed within a cognitive-developmental context. (PCB)

This paper provides an introduction to the Alberta Education Developmental Framework, and describes the provincial department's position on curriculum and the cognitive domain. Intended for use in designing and implementing instruction, the developmental framework delineates the developmental stages and processes through which students progress,…

Reviews the neural modeling principles of learning, perception, cognition, and motor control, discusses their applications to sensory-motor problem solving, and explores possible relationships between that pattern of problem solving and aspects of higher order formal operational problem solving. Cites implications for science education. (ML)

A 1-year lag was found between the effect of an intervention intended to promote formal operational thinking in students initially 11 or 12 years of age and the appearance of substantial science achievement in the experimental groups. A one-year lag on cognitive development and an age/gender interaction were also reported. (Author/KR)

Investigated the relationship between the development of formal operations and the formation of ego identity in adolescence. Obtained significant positive correlations between combinatorial ability and degree of identity, suggesting that high identity may facilitate the application of combinatorial operations. Found some gender differences in task…

The reasoning abilities to be expected of the concrete operational and formal operational student, the percentage of secondary science students that are capable of each type of reasoning pattern, and effective strategies to teach science to concrete reasoners are described. Implications for curriculum development are discussed. (KR)

Psychometric information was obtained on the Longeot test, which measures aspects of formal thinking, from a sample of 884 high school science students in India taking a Hindi version of the test. The test version appears valid for these students and may be used to classify subjects into Piagetian developmental levels. (SLD)
