A model for the development of scientific reasoning in adolescents was formulated largely upon the basis of Piagetian theory. Included as potential determinants of scientific reasoning were experience, age, locus of control, field independence-dependence (FID), rigidity/flexibility, intelligence quotient (IQ), and sex. Causal relationships between…

The development of an instructional model for teaching formal mathematical concepts (probability concepts) to disadvantaged high school students through computer programming and some results from a field test are described in this document. The instructional model takes into account both learner characteristics (cognitive, affective, and…

The purpose of this study was to investigate the relationship between the achievement of some abstract concepts in "molecular genetics" and prior knowledge, formal reasoning ability, and sex. The major findings of the study were: (1) prior knowledge had a high significant correlation with the achievement of abstract concepts; (2) the…

The associations among cognitive automatization, abstract problem solving, and educational performance were studied using 127 fourth to ninth grade students. A number of measures of fast, automatic, and fluent performance (FAF measures) were used: writing the alphabet; reading from a word list; and mentally performing arithmetic operations. The…

The range of meanings of "big" and "little" that mothers and their three children under age two expressed in relatively natural communication situations was studied. Longitudinal data from transcripts of conversations of middle-class mothers and their children were analyzed along with diary records kept by parents of their children's use of size…

The drivers in a battalion about to be deployed to Germany were taught the meanings of international road signs using one of the following techniques: Sign Only, in which the road signs were presented via a slide projector and the names of the slides provided orally by the instructor; Sign Elaboration, which was identical to the Sign Only…

In this seventh-grade language unit, the study of semantics is introduced by an examination of the relationships between words and their referents, particularly in terms of changes of meaning and degrees of abstraction. Classroom activities are suggested to help students become aware of "language liveliness" and the processes of…

This 10th-grade unit in Minnesota's "language-centered" curriculum introduces the complexity of linguistic meaning by demonstrating the relationships among linguistic symbols, their referents, their interpreters, and the social milieu. The unit begins with a discussion of Ray Bradbury's "The Kilimanjaro Machine," which…

Recall lists were presented to 40 black lower class and 40 white middle class children in this experiment. The purpose of the study was to examine a possible explanation of the relatively poor performance of black and lower class children on tasks requiring abstract learning abilities. It was reasoned that the threshold for the production of…

To assess children's ability to draw inferences from selections of children's literature and to measure the significance of various selected factors to this ability was the problem of this study. Children (432) were evenly divided among grades 4, 5, and 6 and randomly divided at each grade level into two equal groups, one of which read the…

This study investigated the effects of instruction in reflective thinking upon impulsive fourth grade students and the transfer effects of this instruction on a classroom social studies test. Thirty impulsive subjects from a white, low socio-economic area school were identified. Treatment and impulsivity were examined as they influenced…

The problem of this study was to determine if there was any difference in fourth, fifth, and sixth grade children's ability to learn the materials in an anthropology unit, "Concept of Culture," designed for the fourth grade and developed by the Anthropology Curriculum Project. Major emphasis of the unit was given to an understanding of…

The social studies curriculum guide for kindergarteners is based upon the idea that thinking is sequentially learned and developed. The aim of the program is to help children develop the tools of reasoning. Emphasis is on the introduction of cognitive tasks involving concept formation and requiring students to list, group, identify, and label…

This handbook for educators and parents discusses the need to include philosophy in the elementary classroom. The authors point out that as a question-raising discipline, philosophy is appropriate to guide children's natural inquisitiveness through the educational process. It encourages intellectual resourcefulness and flexibility which can enable…

A 3-year experiment evaluated the effectiveness of the Pyramid program, an educational program for young children from deprived situations and based on two concepts: psychological nearness (principles of attachment theory) and psychological distance (derived from developmental distancing, or the growing ability of a child to comprehend that an…
