Examines the development of the child's concepts of certainty and uncertainty within the context of concrete and propositional reasoning tasks. Subjects were first, third, and fifth graders. Findings support the position that reasoning about concrete certainty and uncertainty requires a different competence than that required for reasoning about…

Examines the early learning experiences of great men and women mathematicians to determine whether their lives were stimulated in symbol modes that generated semiautonomous cognitive systems of acquiring, processing, and originating vast complexities of abstract mathematical concepts. (HOD)

High school students of various ability levels were presented economics concepts lessons, varied according to their organization or structure. Test questions over concept ranged from simple recall of information to application of economics principles. Students scored generally higher when they were presented highly structured lessons. (LMO)

Explains how a writing course with lyric poetry as its subject matter, when designed according to cognitivist principles, provides an environment in which students can grow as writers and also mature in their ability to respond to literature. (HOD)

Reviews several books that seek to explain what some of the structures of meaning are that stories present to readers and feed into their memories. (HOD)

Presents activities that have been used successfully in leading students from concrete experiences through pictorial and symbolic representations of important numeration concepts and patterns, including place value, multiples, and rounding. Each activity includes concept or skill fostered, list of materials needed, recommended grade level, and…

Judgments of similarities between numbers were solicited from kindergarten, third-grade, sixth-grade, and adult subjects. Results suggested children become sensitive to an expanding set of numerical relations during the period from kindergarten through sixth grade. Results of a second study suggested that the number similarity judgments of…

The ability to perceive and understand that liquid remains invariantly horizontal was studied with 64 hearing impaired junior and senior high school students. Significant results were found for training on the most difficult bottle positions. No differences in performance were found between the male and female hearing impaired students.…

The frequency and type of inappropriate word extensions (i.e., use of ball for moon) in the spontaneous speech of nine young language disordered children (2.8 to 3.4 years old) were studied. The percentage of inappropriate word extensions of these children was comparable to that of normal children at the same level of linguistic development.…

Determined the relationship between counseling systems stages and counselor effectiveness as measured by Carkhuff's accurate empathy scale. Students (N=97) were rated for stage of conceptual functioning. Counseling interviews were rated for level of empathic responding. Results indicated markedly significant differences between and among…

This investigation focused on the stage of formal operational reasoning in the acquisition of astronomy concepts, and on efficacy of different instructional experiences for facilitating cognitive change in college students. Included are selected results and directions for future research. (SK)

Discussed is research which shows, in contrast to the dominant impression given by Piaget's work, that before the onset of schooling the young child possesses several kinds of fundamental "intuitions" concerning numbers. (Author/TG)

Defines interpersonal communication competence, describes a competency-based course offered at the University of Cincinnati, and reports the results of research testing the effects of a skills approach to interpersonal communication instruction. Tests for specific skills of empathy, descriptiveness, owning thoughts and feelings, and…

A general theory of how children learn conservation concepts is presented. The acquisition process is described at an abstract level in terms of a rule-sampling system, implying a three-state Markov model with identifiable parameters. Three experiments testing the model's quantitative predictions about conservation learning experiments are…
