Discusses magnetic polarity stratigraphy as a tool for correlation of fossiliferous terrestrial deposits. Explains the strengths, weaknesses, limitations, preferred conditions, sampling, laboratory analysis, and applications of this technique. A table of paleomagnetic studies on vertebrate-bearing terrestrial sections arranged by age and locality…

Introduces an experiment involving the observation of Brownian motion for college students. Describes the apparatus, experimental procedures, data analysis and results, and error analysis. Lists experimental techniques used in the experiment. Provides a circuit diagram, typical data, and graphs. (YP)

Discusses the average speed differences between hydrogen and oxygen molecules contained in a jar. (YP)

Discussed are the selecting, assessing, and managing of students' investigational works showing how they fit in with the General Certificate of Secondary Education (GCSE) Physics (mature) for London and the East Anglian Group. (YP)

Described are the course, teaching/study, entry qualifications, and destination of graduates of four courses in medical physics from Exeter University, King's College London, University College London, and University College of Swansea. (YP)

Describes a method of instruction used to provide meaningful individualized assignments to students in a large introductory physics course. (ZWH)

Describes an inquiry activity in which students explore the variables that influence the amount of time it takes a ball to roll down an inclined plane. Relates features of the activity to recommendations in the NCTM Standards. (MKR)

Describes the reordering of a ninth-grade physics course that aimed at making core concepts clear to the students while at the same time developing students' skills and depth of understanding. Discusses its benefits and associated problems. (JRH)

Analyzes the cognitive processes and kinds of knowledge needed to work in a scientific domain like physics. Discusses the processes needed to interpret scientific concepts, uses of quantitative and qualitative descriptions, hierarchical ways of organizing scientific knowledge, and processes facilitating problem solving. Describes the use of these…

Describes an activity that uses a candle, a scale, and an elevator to demonstrate the concept of weightlessness in space, showing that astronauts are not truly weightless. Activity includes an exploration phase, a concept introduction phase, and a concept application phase. Provides guidelines and safety measures for conducting the activity. (JW)

Presents an activity that involves construction of a Native American drill to teach about technology, simple and compound machines, mechanical advantage, and force and area. Introduces students to non-Western technological innovations. (JRH)

Presents an exercise that gives students a real feeling for experimental errors and demonstrates the importance of frequent repetition and averaging. (JRH)

Presents strategies aimed at increasing physics enrollment by creating and advertising a physics program that appeals to the majority of students but sacrifices neither rigor nor content. Involves extensively publicizing the class at school and moving the course out of the classroom and into the home. (JRH)

Presents an account of introducing some elements of the history of physics in ordinary physics courses in an Italian high school. (PR)

Describes a performance assessment protocol that rates six goals: (1) methodology of research, (2) use of equipment, (3) accuracy in measurement, (4) application of concepts and formulas, (5) use of mathematics, and (6) completeness and clarity. Provides an example performance task evaluation sheet. (MVL)
