A correspondence exists between a simplified data collection method employing results from a post test for graphic skills in kinematics, and a rigourous validation method. Examination of test responses for discrepant instances yielded further information of value. Hierarchical patterns of learning and remembering are identical. (Author/CP)

Describes a physics course concerned with the physical principles underlying devices used and natured occurrences observed in daily experience. (SL)

A colliding spheres type of experiment is used with several hundred 4-12 grade students to test for knowledge of the concept of controlling variables. Results support the contention that the concept is developed gradually during the concept stage but not fully attained until around 14 years of age. (CP)

Describes the use of science fiction in teaching about the effects of science and technology on human interaction. Questins appropriate for social studies class discussion and tips to teachers on preparing science fiction stories are included. (Author/DB)

Reports data obtained from a sample of British adults on their knowledge of simple biological topics. Analyzes responses according to gender and educational background. Findings indicate that people with a non-science background responded similarly to those with a higher educational level. (ML)

A science unit illustrates the concept of scientific predictions by using how geologists predict where to drill for oil as an example. In a related exercise, everyday items such as bricks, sand, and marbles introduce permeability. Other activities demonstrate how to base predictions on established patterns. A reproducible page is provided. (JL)

Defines the rate-controlling step in contrast to the terms rate determining and rate limiting. Discusses the usefulness of this concept in describing kinetic isotope effects, consecutive reactions, chain reactions, and enzyme-catalyzed reactions. (CW)

Explains how the muscle and bone arrangement of the human body can be used in teaching the principles of simple machines. Presents an activity that investigates the lever system of the forearm. Includes background information on levers and suggests questions for classroom discussion. (ML)

The Six Flags Over Georgia amusement park is the setting for a one-day laboratory exercise and evaluation of high school students' understanding of physics. The concepts and general techniques measured and the park's resources are discussed. Sample student responses are included. (JN)

Data on the semantic proximity of classical mechanics concepts, obtained by means of a cross-sectional investigation (100 subjects) using a continued word association test, were analyzed by individual difference multidimensional scaling to permit the mapping of semantic space for individual subjects. (JC)

Individual interviews of second grade students revealed five qualitatively different concepts of the earth. Audiotutorial lessons used in this study did not result in significant advances in children's concept of the earth. (MLH)

The science component of the North Carolina Standard Course of Study (SCS) is designed to provide learning opportunities for all students to become scientifically literate. Scientific literacy implies an understanding of the scientific concepts and processes needed for personal decision-making, participation in civic affairs, and economic…

According to renowned physicist Stephen Hawking, "science fiction is useful both for stimulating the imagination and for diffusing fear of the future." Indeed, several studies suggest that using science fiction movies as a teaching aid can improve both motivation and achievement. However, if a movie's plot crosses the line between good…

Measurement can develop in the earliest years from children's experience, and it readily lends itself to real-world application. Focusing on research and practice, NCTM's 2003 Yearbook presents current thinking about the learning and teaching of measurement, including students' understanding, the mathematics of measurement, estimation and…

A longitudinal case study focused on the process of conceptual change in science of a young girl. The subject, the researcher's granddaughter, was 6 years and 6 months old and in first grade when the first of 19 hour-long sessions began. Sessions were spread over a two-year period. A concurrent case study was being conducted with the researcher's…
