Many science curriculum development projects have the goal of increasing students' ability to employ scientific or formal reasoning strategies. Argues that longitudinal data of students who acquired formal reasoning strategies as a consequence of specific instruction are needed to provide evidence that these skills will help in other academic…

This study examines the influence of selected performance factors and social role participation upon Piagetian cognitive funcitoning during the aging years. By administering a battery of concrete and formal reasoning tasks and measures of fluid intelligence, the effects of varying instructional set and age of E on the cognitive performance of 80…

A study was designed to examine the relationship between certain measures of cognitive development and reading scores, particularly reading comprehension scores. Forty-one adult basic education students, ranging from 16 to 62 years of age (mean age of 25) and predominantly from lower socioeconomic groups, were administered the following three…

The existence of a time lag discovered in the cross-cultural application of Piagetian tests may result from a socio-economic bias in Piaget's theory. Abstract, formal cognition may reflect a particular social structure, embodying the principles of exchange value, reification, and alienation which govern production and exchange in the…

The complex and multi-faceted nature of the cognitive process of reasoning is discussed. The factor-analytic history of the isolation and definition of the three most important currently recognized reasoning factors (general reasoning, induction, and logical or deductive reasoning) is traced through the psychometric literature, and the…

To investigate similarity judgements in different cultural contexts, the performance of two groups of children on seven similarity tasks and on two tests of metaphor was compared. The 45 Canadian and 45 Canadian-Greek children (ages 5, 8, and 11) had different cultural and linguistic backgrounds but common schooling experiences. The seven tasks…

This study investigated the development of students' abilities to integrate information in stories as an aspect of reading comprehension. Students aged 8, 11, 14, and 18 judged the importance of key statements, which varied in their causal relations within an episode, between episodes, and in a higher-order structure, yielding three levels of…

In Piaget's developmental psychology the fourth and highest stage of human cognitive development is that of formal operations. The research on formal thought instruments is outlined. This study was designed to construct and validate paper-and-pencil instruments which could be used to select students capable of abstract conceptualization,…

Piaget's model of children's conceptual learning and development was compared with Klausmeier's Conceptual Learning and Development (CLD) model in a longitudinal study. The CLD model suggests four successive levels of concept learning: (1) concrete--recognizing an object which has been encountered previously; (2) identity--recognizing a known…

The Conceptual Learning and Development (CLD) Model specifies four levels of concept attainment (concrete, identity, classificatory, and formal) and three uses of concepts (problem solving, subordinate-supraordinate, and principles). Longitudinal and cross-sectional studies of concept attainment may be conducted. The results of this study of 300…

A review of Piaget's theory and research on children's cognitive development is presented, including a discussion of the psychological structures of intelligence, developmental constructivism, and the evolution of knowledge as a subject-object relation. Piaget's assessment techniques are summarized, including moral development, number…
