Children, 4-6 years of age, in special education kindergartens were randomly assigned to a classification training (n 45) and a comparison (n 49) group. Children in the training group were taught the Classification unit of Bright Start, whereas those in the comparison group received a regular content-oriented curriculum. Both groups were given…

The purpose of this study was to investigate the quantifier structuring processes of teacher candidates doing the Abstract Mathematics course of the Elementary School Mathematics Teaching program. Educational activities assisting the students' structuring of quantifiers were provided through transitions between verbal (written) expressions…

Organic chemistry education is one of the youngest research areas among all chemistry related research efforts, and its published scholarly work has become vibrant and diverse over the last 15 years. Research on problem-solving behavior, students' use of the arrow-pushing formalism, the investigation of students' conceptual knowledge and…

University and high school students not pursuing a science, technology, engineering, and/or mathematics (STEM) course of study demonstrate less developed scientific reasoning than their STEM-based peers. Previous studies show that the majority of non-STEM students can be classified as either concrete operational or transitional reasoners in…

The period from adolescence through young adulthood is one of great promise and vulnerability. As teenagers approach maturity, they must develop and apply the skills and habits necessary to navigate adulthood and compete in an ever more technological and globalized world. But as parents and researchers have long known, there is a crucial dichotomy…

Young children's naive beliefs about physics are commonly studied as isolated pieces of knowledge. The current paper takes a different approach. It asks whether preschoolers interlink individual beliefs into larger configurations or Gestalts. Such Gestalts bring together knowledge such as how an object's mass relates to its sinking speed, how an…

The purpose of the study was to determine whether kindergarten children could perform successfully on Piagetian class inclusion tasks and whether their performance was a function of the types of conditions under which the task was presented. Children were asked to classify items based on a physical attribute not visually perceptible (painted…

Piaget's conceptualization of concrete and formal operations is presented. It is contended that Piaget has obfuscated logic, metaphysics and methodology. (MS)

Teaching methods that guide pupils' mental activity and encourage them to employ rational thinking techniques are described. (DB)

Children were asked to judge the life qualities of a stimulus, justify their judgment, and judge again, after being given an anomalous probe. Analysis indicated younger children were unable to adhere to an original judgment when probed, while older children were. Results may reconcile previous empirical discrepancies in Piagetian research.…

Level of cognitive development was not significantly related to humor appreciation for either novelty or incongruity humor in 30 boys at each of three age levels: 5, 7, and 9. (WY)

Study lends support to the view that the problem with left-right stems from the imperfect mastery of the basic discrimination, not from an inability to deal with the logic of relational concepts. (Author/CB)

An analysis of critical thinking is discussed in terms of conceptual interpretations and through determining the logic of linguistic expressions. (Author/RK)

Examines language effects in class-inclusion performance with 224 children ages 3 through 12 by comparing the standard Piagetian question with two alternate question forms. Overall, the findings were inconsistent with the Piagetian assertion that logical inability produces errors in comparing subclasses; inclusion performance was a function of…

Investigated the intercorrelations among tasks that appear to require Piagetian formal reasoning to determine whether formal reasoning is used selectively or all-pervasively. Subjects were 60 undergraduate females. (SDH)
