Investigates Michael Polanyi's theory of emergence of the framework for tacit (personal) knowing, its function in the reasoning process, and the significant role art can play in the development of personal knowledge. States that intensive study of works of art will enable students to make discriminating choices that ultimately evolve into personal…

The application of Piagetian theory to educational practices encounters a series of major difficulties. The main focus of this paper is on the notion of general stages, which has been under attack in numerous studies. Organized in four parts, the paper: (1) discusses the problem of the existence of general stages and of a developmental…

Discusses recent studies related to conceptual understanding in the domain of history, comparing the nature of understanding as found in history to that of other domains. Considers the role of sources in historical knowledge, the role of the historian, causation and explanation, and narrative exposition. (MJP)

This research investigates the development of analogy, in particular, the study of the development of systematicity in analogy. Systematicity refers to the mapping of systems of mutually constraining relations, such as causal chains or chains of implication. A preference for systematic mappings is a central aspect of analogical processing in…

Most of the research on mathematical and scientific thinking has been concerned with uncovering knowledge structures and reasoning processes in people of different levels of competence. How these structures and processes are acquired has only recently become a major concern. Thus, some of the major research on mathematical and scientific thinking…

Explores the intuitive understanding of biology that occurs in early childhood and discusses later cognitive changes that occur. Young children possess a vitalistic understanding (e.g. breathing brings power to the body) that becomes mechanistic (e.g. an understanding of the heart and lungs) as they mature. Includes statistical and tabular data.…

Describes a theoretical framework for the analysis of conceptual change that considers conceptual knowledge as a generative cognitive tool for the creation of more specific mental representations. Argues that a task-oriented interaction between propositional structures and mental models can help learners evaluate the consistency of their…

A quasi-experimental study explored the effect of functional flow diagrams on technical system understanding. An individualized field training package which contained schematic diagrams that illustrated an aircraft's electrical system was complimented with functional flow diagrams. In a 4-week treatment, a control group of 10 students enrolled in…

This article considers relatively neglected resources for the "bootstrapping" of cognitive growth, including chance plus selection, the affective boosting of relevant schemas, the operation of innate biases, and use of spare mental capacity. Implications for educational research are illustrated with reference to recent work on the…

Examines perceptions concerning the shape of the earth and the causes of the day/night cycle among American Indian children. Interviews with 26 Lakota/Dakota elementary children revealed a preference for a synthetic model of the earth and animistic explanations for the day/night cycle. Includes excerpts from the interviews. (MJP)

Reports on an experiment that explored novice learners' responses to anomalous data (new data that contradict previous beliefs). Secondary education students were given both anomalous and confirmatory data concerning various theories about the origin of life on earth. Statistical data reveal their level of awareness of the contradictions. (MJP)

Cognitive theory and research are relevant to vocational education. Three theoretical perspectives underlie cognitive theory-based curriculum and instruction: information processing, knowledge structure, and social history. A review of these perspectives in vocational curriculum and instruction suggests that instruction supporting higher-level…

Two studies examining student images of the world as depicted on sketch maps are compared. The first study collected sketch maps of the world drawn by high school and university students in the United States, Canada, Finland, and Sierra Leone to examine the influence of location on student perceptions. The second study collected maps drawn by…

Investigates effect of computer-aided instruction (CAI) on acquisition of communication skills. Sketches a tutorial of the basic communication structure. Recommends confining CAI to cognitive learning because CAI cannot advance communication skills. Maintains that integrating CAI in social arrangements will allow the computer to remain an…

Discusses the relationship of school size to understanding of scientific concepts. Results indicated that students in small high schools had fewer instances of understanding and more instances of misunderstanding of the concepts of diffusion and homeostasis. No difference was observed for concepts related to food production in plants and…
