Examines the importance of teaching critical thinking and intellectual standards through the use of an engaged lecture style. Indicates that engaged lectures pressure students to intellectually process the information conveyed by the teacher and thus better understand the lecture's content. Describes the key issues regarding the implementation of…

Explores cognitive development in early childhood education and examines four kinds of prevailing misconceptions in the light of recent evidence: (1) infants and very young children are limited to sensorimotor cognition; (2) young children's cognition is animistic; (3) young children's thought is egocentric; and (4) young children can think only…

Training used by corporations and other organizations for management development has undergone changes over the years. The first generation of development training emphasized personal growth through physical challenge. The second generation added an intellectual dimension for processing the experience. The third generation includes physical,…

Music stimulates thought processes and enhances spatial reasoning, which are essential for academic achievement. Research indicates the spatial reasoning performance of preschoolers who receive music lessons far exceeds that of comparison students. Even listening to music proves beneficial to spatial reasoning. Music training seems also to benefit…

Explores the extent of preschoolers' knowledge of mixed emotions, and whether difficulty in discerning mixed emotions stems from beliefs about how emotions are portrayed on the face. Found that both four- and five-year olds can identify mixed emotions. Only five-year olds (with appropriate scaffolding and with simple, clear stories) can…

Observed the reactions of 3.5-month-old infants looking at a carrot that should have but did not appear in a window after passing behind a screen. The results of this and several similar experiments indicated that 3.5-month-old infants are able to represent and reason about hidden objects. (BC)

Examined children's ability to describe, understand the causes of, and realize the value of three types of pain. Preschoolers, elementary school students, and college students were interviewed using open-ended questions. Although older children had more complex and precise understandings of pain, this pattern differed according to the type of pain…

Considers the unique cognitive and intellectual factors that influence the learning and education of older adults. Reviews research on patterns of intellectual and cognitive aging and the implications of patterns in attention, memory, information retrieval, and tolerance for interference in the development of cognitive training programs for older…

In one experiment, second and fourth graders used more categorical information when they made inferences than did preschoolers. In two other experiments, second graders, but not preschoolers, distinguished between categorical information and appearance when they made inferences about known concepts and familiar properties. (BC)

Preschoolers were shown three objects in a given category. Each object had two attribute dimensions. A target category object with two different attributes was presented. Information provided to the children through verbal labeling or variations in a given category attribute both elicited induction of the defining attribute in the novel target…

After an overview of several studies of cognitive instruction used with problem learners, the article describes two learning mechanisms that explain why such cognitive interventions work--prolepsis (communication that initially leaves implicit some information) and reflective abstraction (changing observables into meaningful internalized…

The effects of neurotoxins on the development of the central and peripheral nervous systems are discussed. Organophosphates, carbamates, organic solvents, and dioxin are highlighted. The effects of long- and short-term exposure are described. (CW)

Presented is an alternative method for analyzing the van Hiele level of students' geometrical reasoning. The accuracy of students' answers may afford a description of acquisition and/or expertise for each of the van Hiele levels simultaneously rather than the traditional assignment and evaluation of one level at a time. (JJK)

Questionnaire results indicate that, although first-year, undergraduate science students (n=109) recognize the correct sources of energy for organisms, they simultaneously hold misconceptions about other essential, but nonenergy-supplying, conditions as sources of energy supply. Occurrence rates for these misconceptions vary with the students'…

Describes the history of five selected problems from mathematics that are included in an undergraduate honors course designed to utilize original sources for demonstrating the evolution of ideas developed in solving these problems: area and the definite integral, the beginnings of set theory, solutions of algebraic equations, Fermat's last…
