Applies to the inclined-plane task Siegler's (1981) observation that performance on Piagetian tasks is governed by similar rule structures. Also replicates Siegler's original observations about the development on the balance-scale task and determines the consistency in children's rule usage across tasks. (Author/AS)

This study hypothesized that subjects who display proportional responses on the Pouring Water Task have developed the ability to comprehend logical arguments of the form referred to as "reasoning to a contradiction," while subjects who display additive responses on the same task have not. To test this hypothesis, 100 additive and…

This study examines the nature of the highly variable black-white difference across diverse tests and indicates the major systematic source of this between-population variation, namely, Spearman's g. Eleven large-scale studies (discussed in the appendix), each one comprising anywhere from 6 to 13 diverse tests, show a significant and substantial…

Examined the relationship between 7-, 9-, and 11-year old children's performance on a battery of selected Piagetian measures and on a proportional reasoning task. Found a strong relationship between stage level and (1) the complexity of hypotheses used, (2) the use of the proportional hypothesis, and (3) the overall use of logical hypotheses. (HOD)

Focuses on differences occurring with age and reading skill in the use of phonemic codes in short-term retention tasks where stimuli were presented visually. Subjects were groups of average readers in grades two, four, and six; superior readers in grade four; and disabled readers in grades four and six from three public schools. (Author/RH)

Some central issues in discussions of creative processes in science are: (1) the mechanism(s) by which hypothesis formation takes place; (2) the sources of new knowledge during hypothesis formation; and (3) the "Eureka" versus steady accumulation (accretion) issue concerning the pace of change during hypothesis formation. This paper…

Describes study of children in grades one, three, and five that examined their active processing and short term memory (STM) of color, contour, and interior pattern of shapes found in computer digitized pictures. Age-related differences are examined, and the role of processing visual information in the learning process is discussed. (12…

High and low level questions as determined by a panel of evaluators were combined with corrective feedback and attribute isolation feedback to form four versions of a computer-based science lesson. The sample consisted of 154 high school chemistry students in a suburban high school. The primary hypothesis was that students who received high level…

Compares the use of four different versions of a map by fourth and fifth grade students with a computerized adventure game which simulated an environmental exploration. Variables examined included type of map and student gender, ability to learn place location information while playing the game, and enjoyment of the game. (RP)

Two studies were conducted to extend the application and explore the parameters of the concept tree and rational set generator instructional design techniques. The first study was conducted with high school English students. Results indicated that students who studied the concept tree performed no differently on the classification tests than…

Conducted to determine whether use of computerized file-management programs can enhance the development of information processing skills, this two-treatment experiment found that seventh through twelfth grade students in the computer-using/structured activities group received significantly higher mean scores than the…

This paper considers the style and structure of broadcast educational television programs in relation to learning outcomes, and proposes a study to identify those key factors which intervene or affect this relationship. The types of structure examined include simple or complex and self-standing or integrated programs, and types of style include…

To examine the role of elaborations in learning a procedural skill (i.e., using a personal computer) from an instructional text, 88 members of the Carnegie-Mellon University community (students, faculty, and staff members) participated in two experiments. Experimental sessions consisted of a reading period followed by a task performance period in…

This paper focuses on the importance and the significance of the teacher's mastery of an abstract body of knowledge that underlies an educational innovation. Concepts and principles from organizational sociology are applied in order to investigate the relationship between teacher's mastery of this body of knowledge and the process of…

The Scientific Theory and Method Project (STAMPS) is concerned with students' understanding of two areas of science in secondary schools. One is understanding what a scientific theory is, and the other is understanding the methods used in conducting scientific research. In the science curriculum these topics are often described as the process of…
