Advocates an ideology stressing survival of the planet. Discusses major changes in the concept of war since the advent of nuclear warfare. Considers three stages for the development of peace: negative peace, nonviolence or conflict resolution, and positive peace. Reviews research on young children's capacity for understanding peace concepts. (AC)

A model of critical thinking is developed, encompassing problem solving and creative thinking. The central role of critical thinking in adult education is explored, concluding that development of the concept and how to teach it need attention. (SK)

Describes MATRIX-1, a small group activity that can be used to show interrelationships between various factors. Examples include values clarification; procedural phases; relationships among people; resource allocation; related concepts; and group decision making activities. Modifications to MATRIX-1 are discussed that allow for variations in…

The conceptual categories that children have developed in their second year were studied in five experiments using object manipulation tasks. Subjects included 152 children from 18 to 31 months of age. These very young children had formed global conceptions of many domains of objects. (SLD)

Six studies examined the effectiveness of the elaborative interrogation teaching strategy, which involves students generating answers to "why" questions about facts about to be learned. The preschool and elementary students demonstrated higher factual recall when they were instructed to use their own elaborations of facts rather than…

This research endeavored to study student's views of science through their operative definitions of science. The results were used to create an instrument with which teachers could evaluate students' perceptions of science and then prepare lessons that address misconceptions. (PR)

Order and entropy exist in all human and environmental processes. Technological innovation begins with entropy, and problem solving creates order. Humans learn by building order through conceptualizing but create entropy by not using a wider range of learning methods. (SK)

Among the conclusions from an microanalysis of 29 high school physics student's concept mapping behaviors were that concept maps lead to sustained discourse on the topic and improved declarative knowledge. On the negative side, concept maps let scientifically incorrect notions become ingrained and go unchallenged. (PR)

Recounts a teacher's experiences with a small group of elementary school students as they explore different forms of the combinatorics problem of choosing two out of five objects. Describes how students examine the connections between the problems and a proof of the relationship. (MDH)

Describes the use of concept maps and Vee maps in science instruction. (PR)

Argues for an approach to conceptual-change instruction that places students' science conceptions and their ability to reflect on those conceptions at the center of science instruction. Focuses on the effect of using status concepts. Contains 24 references. (DDR)

Presents a summary of teaching practices that are successful in promoting conceptual change based on a study of Grades 4, 8, and 10 and on the research literature. Proposes improvements in teaching methodology. Contains 31 references. (DDR)

Explores dynamic modeling as an opportunity for students to think about the science content they are learning. Concludes that creating dynamic models has great potential for use in classrooms to engage students in analysis, relational reasoning, and synthesis. Contains 21 references. (DDR)

Describes an experiment in which the density of solutions of known sugar concentrations is measured. Data are then used to determine sugar content in commercial beverages. (DDR)

Reviews the perspective of Donald Campbell on creative thought and argues that the role of blind variation and selective retention in Darwinian evaluation and human invention is different. Proposes that a contrast can be drawn between "smart" and "not so smart" blind variation. (CR)
