As biological and socio-cultural beings, humans are encouraged and aspire to "see" not only what comes "within sight," but also what is not possible to see. Visualization is described as offering a method of seeing the unseen. These ideas are organized into sections that focus on seeing the unseen in data, seeing the unseen in…

A movement of educational change in Portugal aimed at giving schools larger autonomy in curricular decisions is described. In reconceptualizing curriculum, the concepts of competence and innovation played a central role. An analysis of the curriculum development process is included and some suggestions are offered for future research and debate.…

Takes a situated-cognition perspective on learning and cognitive development. Presents a detailed framework that includes operationalizations for levels of situated learning. Contains 31 references. (DDR)

This paper focuses on some main distinctions that are necessary to analyze mathematical knowledge from a learning point of view and explain how many students come up against difficulties at each level of the curriculum. From a learning point of view, visualization cannot be used as an immediate and obvious support for understanding, even though it…

Provides a comprehensive review of literature regarding misconceptions that are held by secondary students in chemistry. Makes some recommendations based on the research. Contains 77 references. (DDR)

This paper explores a framework for research on the development of the angle concept based on theories of abstraction. The framework suggests that children initially acquire a body of disconnected angle knowledge situated in everyday experiences, group the situations to form angle contexts, and then form an abstract angle concept. The framework is…

Cognitive flexibility is indispensable for applying knowledge to new situations. The development of this ability depends on certain conditions such as the attainment of a deep comprehension of the subject matter and the exposure to different knowledge representations. This paper focuses on these conditions and describes a study designed to foster…

This study of physics problem-solving identifies reasoning mechanisms that enable the problem-solver to achieve the transformation to a physics structure of the problem situation. Elaboration is explored as a mechanism in fulfilling this transformation by providing beginning problem-solvers with elaborations that they failed to infer. A card…

This paper presents findings from a study that investigated students' understanding of quantum phenomena and focused on how students incorporate the ideas of quantum physics into their overall cognitive framework. The heuristic metaphor of the map is used to construct graphic representations of students' understanding of quantum physics. The…

Explores the interaction between scientific epistemological beliefs and learning orientations in a group of Taiwanese eighth-grade students. Suggests the importance of employing a constructivist philosophy in the classroom. Contains 55 references. (DDR)

This study addresses questions about particle physics that focus on the nature of electrons. Speculations as to whether they are more like particles or waves or like neither illustrate the difficulties with which students are confronted when trying to incorporate the concepts of quantum physics into their overall conceptual framework. Such…

Educational research is distinctive inasmuch as it shares the moral objective of education, which is to help people make the best of themselves through processes of learning. Educational research is a service industry for education. As such, its contribution to the efficiency and effectiveness of educational processes can be increased by focusing…
