Indicates that the evidence in support of an identity-equivalence sequence is much weaker than Brainerd and Hooper claimed. Suggests that for most children, identity and equivalence appear to be contemporaneous developmental achievements. Some general methodological and theoretical issues raised by the identity-equivalence studies are discussed.…

Examines the relationship between the fantasy development and conservation performance of second grade children. Results suggest that children's ability to fantasize is not significantly correlated with performance on conservation tasks at this age level. (BD)

This study examined the effects of judgment-contingent feedback and prior knowledge of 3 rules on the conservation learning of 188 kindergarten children. (Author/JMB)

This study is a replication of Piaget and Inhelder's intertask study of conservation and conservation-related tasks involving subjects ranging in age from nursery to second grade and using varying types of vessels. (SB)

The strength of the tendency of children (aged 4 1/2 to 7 1/2 years) to give phenomenist reading of neutral questions about object properties was investigated. Phenomenist answers decreased with age, and social dominance and conversational context affected answers. (SKC)

Hypothesizes that children may misunderstand the task required by Piaget's test and that researchers may therefore underestimate the children's cognitive capacities. Tests the hypothesis by dividing 48 children of both sexes into two groups, those taking the standard tests and those taking a test restructured to limit ambiguity. (BE)

A refinement of Hofmann's paradigm for conservation training is proposed. It is suggested that a delayed learning task be utilized for assessing generalization. This, it is argued, would be also be a more preferable measure of whether or not new cognitive structures have been acquired. (Editor)

The Progressive Architecture Awards Jury gave citations to three projects grouped as "the response by architects to environmental problems." One citation was awarded to a college campus design utilizing solar energy, recycled materials, and wind power. (MF)

This second article in a series on energy conservation sets up an overall attack on energy waste in the school environment. The campaign begins with proper operation and maintenance procedures. (See EA 005 433 and EA 504 535 for related information.) (Author)

Non conserving first- and second-grade children were tested on conservation tasks. Eye movements were recorded during the response period for each task. Trained conservers showed more visual exploratory behavior and less perceptual centration than control subjects. (ST)

Investigated whether children will relinquish belief in Piagetian concepts upon presentation of disconfirming evidence. The conservation of weight concept extinguished more readily than transitivity of weight, and only for the latter was a developmental trend evident. (DP)

Preschool and kindergarten nonconservers (N=114) were examined for their use of dimensions relevant to quantity in two conservation-of-substance tasks. The results were interpreted as being counter to Piaget's 4-step equilibration model of the development of compensation and conservation. (ST)

Warns that in any crisis, those who over-react to find a solution threaten to cause a second crisis. Takes a look at lighting criteria, energy sources, and methods of conserving them. (Author)
