Science curriculum and instruction in K-12 settings in the United States is currently dominated by an emphasis on the science standards movement of the 1990s and the resulting standards-based high-stakes assessment and accountability movement of the 2000s. We argue that this focus has moved the field away from important philosophical…

Proposes a mechanistic model for development and evaluation of national elementary and secondary school science curricula. (JM)

Presents the conceptual levels theory of Hunt and his associates. Indicates how it can be used as a means to develop a theoretical framework from which the validity of unified science curricula can be examined. (HM)

The interdisciplinary and multidisciplinary curriculum at the experimental high school on the Sde Boker campus of Ben Gurion University in the Negev, Israel, is described. It is viewed as a worldwide model available to academic communities to study the impact of environment on survival of all living things. (MP)

Outlines the use of computer programs in modeling and simulation to provide a link between science and mathematics education. (GS)

Proposed is a plan for changing elementary school teachers' attitudes toward science. Persuading teachers, a mandate to teach science, and rewards for teachers involved in science curriculum development, the three steps in the model, are presented in some detail. Implementing the model is also discussed. (MNS)

Presents a practical model for planning and implementing a field trip as an integral part of the science curriculum. Reviews the literature related to the role of field trips in the learning process; describes the model; and provides an example implementing the learning cycle method. (Contains 17 references.) (MDH)

A number of national science and mathematics education professional associations, and recently technology education associations, are united in their support for the integration of science and mathematics teaching and learning. The purpose of this historical analysis is two-fold: (a) to survey the nature and number of documents related to…

Investigates the construction of understanding of the motion of an object down an inclined plane which takes place through the process of model building in an integrated algebra, trigonometry, and physics class. Discusses four major themes related to student learning through modeling that emerged from the results. Discusses implications for…

Examines a number of factors that should be of importance in science teacher preparation and presents a model for designing a program for future elementary school science teachers. (JR)

Describes the experiences of six science teachers and a facilitator involved in an action research group in science, technology, and society (STS) education. Explores the genesis of an issues-based model and highlights applications of this model in a classroom context. Examines action research as a potential tool for professional development in…

Discusses six aspects of the Berlin-White Integrated Science and Mathematics Model developed to address the need for a definition of the integration of science and mathematics education. These aspects are ways of learning; ways of knowing; process and thinking skills; content knowledge; attitudes and perceptions; and teaching strategies. (MKR)

Reports that young children in the pedestrian accident prone age range of four-eight years hold a variety of naive conceptions regarding speed. Proposes a primary science unit using a conceptual change approach. (MVL)

Students' conceptions of three major artificial intelligence concepts used in the modeling of systems in science, fuzzy logic, neural networks, and genetic algorithms were investigated before and after a higher education science course. Students initially explored their prior ideas related to the three concepts through active tasks. Then,…
