Reports research designed to explore the possibility that conceptually different forms of common-fraction understanding can be identified. Such forms may be associated with differences in fraction problem solving-performance. Contains 50 references. (DDR)

Explores the effects of Roundhouse diagram construction on a previously low-performing middle school science student's struggles to understand abstract science concepts and principles. Based on a metacognition-based visual learning model, aims to elucidate the process by which Roundhouse diagramming helps learners bootstrap their current…

Examined whether gender differences exist within cognitive stages and whether gender differences exist at the cognitive stage level in college freshmen (n=86). Longitudinal study found students' epistemological development revealed gender differences in epistemological reasoning structures but not in cognitive structural stages. (Author/ABL)

Outlines a cognitive model of visitors based on the concept of mindfulness/mindlessness. Presents an analysis of data on visitors to forestry centers in the United Kingdom. Results support the mindfulness approach as an appropriate cognitive model of visitors. (Author/CW)

Restructuring constraining thoughts is an important step in career counseling. A collaborative approach enables counselors to assist clients in (1) recalling distressing situations, (2) determining associated thoughts and feelings, (3) discovering underlying beliefs, (4) summarizing the thoughts, and (5) examining the relationship between beliefs,…

Describes and compares physics students' understanding of concepts associated with electric and magnetic fields using interviews and written tests. Provides insights into a more detailed view of students' understanding of fields using the theoretical framework of the Structure of the Observed Learning Outcome Taxonomy. (Author/MKR)

Using conceptual change as theoretical lens, describes the structure of (n=4) learners' conceptual ecology within biological evolution and illustrates how this ecology influences the process of conceptual change. Prior conceptions relate to evolutionary theory, scientific and religious orientations, view of biological world, and acceptance of…

One important characteristic of rational action is that intentions should be consistent with beliefs. Two studies examined whether three year olds understand belief constraints on intention. In both studies, subjects' understanding of unfulfilled intentions was excellent and significantly better than their understanding of false beliefs, but…

Considers empirical evidence and theoretical issues that point out the need to reconceptualize individual differences in psychology. Studies use of arithmetic in everyday life and in the classrooms to explore consequences of cultural practices, the nature of individual differences in "ability," and links between practices and identity.…

Reviews Karmiloff-Smith's "Beyond Modularity," suggesting that her work highlights phenomena that seem counter intuitive when regarded from current developmental frameworks, and advocates that understanding them requires more complex perspectives than can be supported by either extreme nativist or domain-general models of cognitive…

Presents a refined form of a personal theory of learning that examines two distinct parts of the complex interaction between a learner's internal mental structures and his or her world of experience. (Author/MKR)

Three theoretical concepts have implications for workplace educators: reflection on experience, linkage between personal meaning and social/contextual meanings of organizational culture, and transformation of personal frames of reference. (SK)

Describes two stages of potential development that could make multimedia the core of an information infrastructure for educational reform: (1) incorporating hypermedia to enable knowledge construction by learners; and (2) using visualization and virtual communities to create artificial worlds.

Isolates domain-general decision-making (DM) processes in their specific instantiations in adult second-language acquisition (SLA). Some impediments to success in SLA may be artifacts of mature (adult) DM procedures. (Contains 29 references.) (JP)

Describes a theory of cognition which posits specialized structural systems (SSSs) that enable individuals to represent and understand domains of knowledge. Three test batteries assessed 12-16 year olds' abilities to think combinatorially, form hypotheses, design experiments, and construct models or theories. Suggests that the results of tests…
