Variations On Piaget's Pre-Number Development Tests Used As Learning Experiences, Hyrum E. Richards

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The effects of learning upon the rate of conservation attainment and its transference to other areas of performance were studied using 17 mentally retarded subjects.

Subjects found to be non-conservers on pretests were taught conservation and correspondence using a variety of tasks modeled from Piaget's experiments. They were also pretested on the WISC Information and Picture Arrangement Sub-tests and a number concept test. Following the learning experiences, the subjects were posttested using the same measures used for pretesting with the exception of the number test where an alternate form was used.

Significant correlations were found between the conservation pretest scores …

The Use Of Mental Imagery Among Young Children In The Acquisition Of Piaget's Principles Of Conservation, Richard C. Sweetland

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study attempted to discover some parameters in terms of mental age at which young children, ages five through eight, begin to utilize effectively their mental imagery in the learning process. Using Piaget's principles of conservation as a learning task, subjects were taught in one of two groups: Group one was instructed in conservation concepts by use of concrete example, in which case they were allowed to see, handle and manipulate materials as they underwent transformations. Group two received identical instruction but were called upon to use their mental imagery to visualize the materials undergoing transformations.

Based upon the administration …
