Describes a laboratory activity "Observing Reactions in Solution." The activity can be used either as a laboratory or as a performance assessment for a high school chemistry class. (PR)

Explains reasons why students have misconceptions concerning pendulum swings. Presents a series of 10 pendulum task cards to provide middle-school students with a solid mental scaffolding upon which to build their knowledge of kinetic energy and pendulums. (PR)

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)

Describes an experimental sequence using the force probe to develop the relationship between net force and acceleration. (PR)

Presents a lab experiment to demonstrate application of the iterative capability of spreadsheets. Activity involves a variable spacing parallel-plate capacitor and an electrometer. (PR)

From a study of students in 7th through 12th grade it was concluded that salient external features of the problems, as well as factors related to the solver largely influence students' responses to the problems. The theoretical framework, however, is not the most influential factor in determining students' responses to the problems. (PR)

Suggests ways to bring home to the introductory physics student some of the excitement of recent discoveries in particle physics. Describes particle detectors and encourages the use of the Standard Model along with real images of particle tracks to determine three-dimensional views of tracks. (MVL)

This article describes an integrated program in marine biology. The program was implemented in a nongraded inclusive setting with second- to fourth-grade students whose abilities ranged from gifted to learning disabled. The program integrated science, art, music, language arts, and research and computer skills. (DB)

Two chapters of the book, "Toward Inclusive Classrooms," are abstracted here. The chapters concern team teaching a seventh-grade science class and developing a sixth-grade science exhibition. They show how teachers cooperated to plan for inclusion of students with disabilities, how difficulties were handled, evaluation procedures, and…

A survey of university freshmen investigated structural gender differences in learning behavior, based on recollections and report of science study in the final year of secondary school. It is concluded that the differences that emerged are only partially interpretable as classic deep or strategic structures and that gender-sensitive sources of…

Two experiments examined how learning from different media--real pulley systems or simple line diagrams--affected mechanical learning and problem solving. The first showed that subjects' learning improved equally in both cases; all subjects showed an increase in quantitative understanding as they learned; and subjects manipulating real pulley…

Discusses reasons for implementing multicultural science education in classrooms across the country. Examines classroom demographics, the need for a more scientifically literate populace, the demand for more scientists and engineers, and the demand for social justice. Contains 16 references. (LZ)

Writing/drawing activities, picture quizzes, and questionnaires of elementary school children in England and Australia found that the high profile of design and make in the England and Wales Technology National Curriculum was reflected by children's emphasis on model-making, an aspect generally ignored by Australian children. (34 references)…

Presents an activity integrating mathematics and science intended to introduce students to the use of metric measurement of mass as a way to increase the meaningfulness of observations about variables in life sciences. Involves measuring the nutrient tolerance of algae. Contains a reproducible algae nutrient graph. (Author/MKR)

Outlines arguments for action research approaches to the implementation of STS education. Presents six teachers' initial views and changing perceptions throughout the duration of an action research project in terms of four categories: nature of STS education, development of curriculum materials, personal/professional development, and collaborative…
