Argues that much of the conceptual-change literature does not study change per se, but infers, often from interviews, changes in students' conceptions and discourse during learning. Concludes that what is needed are descriptions of learning trajectories. Contains 17 references. (DDR)

Explores some current concepts of curriculum integration, and proposes some alternatives to the conceptual violence often done in the name of curriculum integration. What is lost in many efforts in curriculum integration is the "topography" of any particular thing. Curriculum integration should rely on relationships that already exist and not…

Changes in grade 10 students' (n=79) conceptions of genes during genetics instruction was studied from multiple perspectives. Ontologically, most students moved from passive to active models of genes. Affectively, students were interested in genetics but unmotivated by microscopic mechanistic explanations; however, teaching approaches were…

Examines students' explanations of the greenhouse effect and the hole in the ozone layer, using a life-world and scientific dichotomy. Illuminates ideas often expressed in classrooms and sheds light on the progression in students' developing powers of explanation. Contains 17 references. (DDR)

Examines 250 sixth-grade students' understanding of arithmetic average by assessing their understanding of the computational algorithm. Results indicate that the majority of the students knew the "add-them-all-up-and-divide" averaging algorithm, but only half of the students were able to correctly apply the algorithm to solve a…

Explores common alternative conceptions of a natural science topic familiar to students that was part of the regular curriculum. Finds that similar misconceptions are evident in upper and lower elementary school students. (Author/CCM)

Investigates the effectiveness of utilizing analogies to effect conceptual change in students' alternative-probability concepts. Results indicate that analogies can be effective in producing desired conceptual change in high school students' probability concepts. (Author/CCM)

Maintains that Madole and Oakes' hypotheses are incorrect. Shows that conceptual development frequently goes from the abstract to the concrete and that extensive literature shows that there is more than one kind of categorization. Discusses ways in which perceptual and conceptual categorization differ. (Author/KB)

Examines, within a situated-cognition framework, the teaching and learning of a concept in biomechanics, the manual techniques and tactile discrimination skills that accompany it, and the diagnostic frame of mind that informs concept, technique, and skill. Draws on observations of a class of physical-therapy students. (Author/SLD)

Describes a study in which 383 children in grades 1 through 5 were individually interviewed to find out at what point they construct unit iteration out of transitive reasoning. Indicates that most children construct unit iteration out of transitive reasoning by fourth grade. Suggests a better approach to the teaching of measurement that presents…

Supports the need for study of the foundational concepts of nursing. Evaluates nursing teachers' experiences in implementing a foundations unit, showing that it raised conceptual awareness and helped students link theory and practice. (SK)

Examined students' conceptualizations of learning with 519 Australian, Indonesian, and South African undergraduate and graduate students using the Reflections on Learning Inventory. Analysis did not support a single, clearly defined empirical model of conceptions of learning and associated constructs. Instead, there was consistent evidence that…

The mechanism of routine practice and problem solving that is used as a method of teaching and learning is not simply interpreted as a way in which students only mechanically imitate and memorize rules and skills. Manipulative practice is the genetic place of mathematical thinking and the foundation of concept formation. (ASK)

Investigates the knowledge and understanding among 482 students nearing the end of compulsory education of genetics. Finds a poor understanding of the processes by which genetic information in transferred and a lack of basic knowledge about the structures involved. (Author/CCM)

Presents the concept of interdependence and outlines the use of a concept approach in environmental education. Describes two activities that can be applied to an existing curriculum. (Author/CCM)
