Active principal leadership can help sustain and scale science curriculum reform. This study illustrates how principal leadership developed in a professional learning community to support a technology-enhanced science curriculum reform funded by the National Science Foundation. Seven middle school and high school principals in one urban-fringe…

The study reported here extends the investigation begun by Piaget of content effects to laboratory and naturalistic tasks. If the accuracy and completeness of the subjects' expected variables is related to content, then performance on laboratory and naturalistic tasks should differ systematically. The subjects' expected variables were measured by…

A science program in which students were encouraged to select their own project goal as well as the apparatus to accomplish this goal was developed and tried in two 5th grade classes. (Author)

Discusses whether and how computer programing courses can teach problem solving. Provides results of an integrated set of studies of middle school programing students whose problem solving skills increased in a programing class. Argues that "exemplary" instruction is more efficient than "typical" instruction. Examines the influence of students'…

Implications for science curricula and instructions of new perspectives on scientific knowledge, on nature of evidence, and on how knowledge changes are considered. Argues that much of science education is mired in positivist assumptions and suggests ways in which science instruction can promote a more appropriate epistemological attitude and…

Recent research in science education examines learning from four foci: (1) concept learning; (2) developmental; (3) differential; and (4) problem-solving. These perspectives provide a framework for identifying mechanisms of change in knowledge/thinking processes. In-depth coverage of several science topics may benefit students more than fleeting…

Discusses research on middle school science learning and instruction that suggests how generative models of scientific phenomena can be developed. The Computer as Learning Partner curriculum is introduced as a curriculum that provides a firm foundation for lifelong learning through the use of authentic questions. (SLD)

Considers three main components of self-directed learning: (1) topic knowledge; (2) procedural skills; and (3) self-monitoring. The role of computer-assisted instruction in autonomous learning is discussed, software that fosters independent problem solving is reviewed, and it is recommended that computers be incorporated in courses emphasizing…

Research offers important suggestions concerning science curriculum design, and real-time data collection technology offers great opportunities. This paper discusses how recent increases in understanding the nature of the learner and the process of instruction combined with recent advances in technology might lead to improved science instruction.…

Reported is a study to investigate the effects of a free-choice program on children's ability to interpret experiments, design simple investigations, and recognize variables that could affect the outcome of observed events. (Author/SA)

It has been suggested that cognitive style interacts with performance on tasks measuring formal thought. It is hypothesized that cognitive style interacts with task context rather than with the underlying formal thought processes. Experiments are reported to clarify the type of task that elicits an interaction and to determine whether such…

How students restructured their scientific ideas in response to contradictions was studied with 166 male and female students (aged 12 to 14 years) who tested their predictions about water displacement by experiment. Conceptual change varied; all subjects tended to hold onto old ideas, even when presented with conflicting information. (SLD)

Presented is a discussion on the value of science and technology centers in providing learning experiences for visitors. The discussion is not limited to science centers but includes applications possible to any museum interested in providing interactive experiences. (SA)

Groups of teachers and schools can bridge the theory-practice gap by using the Web-based Integrated Science Environment (WISE) project library. The WISE learning environment promotes lifelong learning along with language and technology literacy by making science accessible, thinking visible, and learning a cooperative experience. (Contains 16…

Gives historical account of research and practices associated with precollege science laboratories. Described three social contexts of research on science laboratories: separation, interaction, and partnership. Argues that more partnerships are needed to continue improvement to the science laboratory, suggesting that future partnerships will…
