Reported is a study of 1555 students, grades 4-12, regarding understanding the concept of controlling variables. Subjects were examined on a task involving spheres rolling down an incline and striking a target sphere; they were evaluated upon their explanations of answers, not their choice of answers. Findings indicated that the Piagetian stage of…

Reports the results of a study designed to measure any changes in the Piagetian level of intellectual functioning of students after taking one introductory college physics course for one semester. No developmental progress was found as a result of taking such a course. (Author/GA)

Seventy-five preservice elementary school teachers were given a Piagetian-related paper-and-pencil test involving the equilibrium of a beam balance. Results show a significant positive relationship between the developmental levels of the clearness, as measured by the test, and their performance on equation solving when different reversible…

This document reports the results of two studies performed to determine the effectiveness of special lessons in facilitating the attainment by children of the basic concept "tree." The first study, which utilized 103 fifth-grade students, also investigated the effects of pretesting. Results showed no significant effects of pretesting and…

Comments on a recent article by DeLuca on electronic "measurement of logical thinking" questioning four aspects of the article. DeLuca responds to the criticism on those four aspects in question. (GA)

Reports a study of the correlation between intellectual development and students' understanding of scientific concepts and science processes. Results are reported concerning the reliability and validity of Piagetian or Piagetian-like tasks as measures of students' level of formal reasoning. (Author/SA)

Sixty-six elementary education upperclassmen were tested to determine their Piagetian stage of intellectual development. Results indicated 26 percent were very formal, 52 percent formal, 15 percent transitional, and 8 percent concrete. (SL)

This document reports data on 610 secondary level Australian high school students drawn from 36 urban and rural high schools to determine levels of Piagetian cognitive development, provide a profile of field independence (FDI) across the urban population, validate the Understanding in Science Test instrument, and determine influence of reading…

Briefly reports on a study involving 419 randomly selected secondary school students who were given five Piagetian tasks to identify their level of cognitive development. (PEB)

An investigation of selected research projects which focus on intellectual development is presented. The treatment begins with a description of psychological-oriented studies and illustrates the many ways in which studying a second language in school settings contributes to the cognitive development of the learner.

Reported is an attempt to examine the nature of the reasoning used by college students who consistently erred on timer tape problems and a comparison of their performance with that of students who made logical responses. The author suggests that the poor performance of students, classified as intuitive responders, is a result of their use of an…

This thesis reports a study of the effects of two types of advance organizer instruction, expository (EO) and guided self-discovery (GSDO), in teaching hierarchical classification or relations to preschool children. In the study, four experimental and one control group received three 25 minute instructional sessions. Using the same materials,…
