Experiment compares the effect of equilibration type training to the effects of S-R reinforcement type training in developing weight-conservation concepts in second and third grade pupils. S-R group performed significantly better than control group on initial posttest for conservation of weight. A measure for permanence of the conservation beliefs…

This study investigated the relationship between conservation of length and impulsive-reflectivity. Kindergarten and first-grade students were administered two conservation of length tasks and an impulsive-reflexive scale. No statistically significant relationship between the two concepts was found. (FL)

In a replication study, children 3 and 4 years old were given verbal rule training in order to probe the importance of identity, reversibility, and compensation explanations in training number and length concepts. Among the results, as before, identity was found to be the most significant factor in conservation acquisition. (Author/RH)

Two experiments were conducted to investigate children's performance on different number versions of identity and equivalence conservation tasks. Subjects were 88 children ranging in age from four to six years. (MP)

In a study to determine procedural effects of volume conservation tasks performed by adolescent females, the results revealed that the LaVatelli water displacement test was significantly more difficult than the Elkind test or Piaget's test. (Author/RL)

Kindergarten and first-grade children conserved physical attributes of inanimate objects more easily than the physical attributes of animate objects. Significant conservation differences between various animate objects also were found. (Author/RL)

Some young children presented with unidimensional and nonverbal conservation tasks were able to give a conservation response if they could answer with a picture instead of orally. (Editor)

The formal operations skills and problem solving performance of 60 gifted girls (grades 4 through 6) were investigated. Ss were given Piagetian tasks which involved conservation of mass and weight, use of proportion, oscillation of the pendulum, and projection of shadows. Among findings were the following: (1) no relationship between IQ and either…

This study reports a factor analysis of the data resulting from a 3-year longitudinal investigation into conservation of number and related mathematical type concepts. Conservation of number, which represents a subset within the concept of conservation, was measured by use of a 20-item, criterion-referenced testing device. The subjects, who were…

The purposes of this study were to determine the feasibility of group testing of conservation and examine the differential performance of students drawn from various populations. The effects of three factors were examined: grade level (2, 4, 6), SES (disadvantaged, advantaged, and race (Black, White, Latin). (Author)

The goal of this study was to investigate improvement in the usage of equivalence and order relations under specified instructional conditions. Forty-eight upper middle class kindergarten children were given a 14-session pretreatment designed to define two equivalence and four order relations of length and matching, followed by tests of…

Two experiments investigated the relative efficacy of two conservation training procedures and the transfer of training to another type of conservation. (SB)

A comparison of 28 mildly mentally retarded children with 28 children of average intelligence (mean mental age six years) in learning conservation skills found both groups benefited from Direct Instruction methods, but retarded children acquired only pseudoconservation from Observational Learning methods. Their learning was not tenacious and did…
