Researchers and practitioners alike express concerns about the conceptual difficulties associated with the concepts of momentum and kinetic energy currently taught in school physics. This article presents an in-depth analysis of the treatment given to them in 44 published textbooks written for UK secondary school certificate courses. This is set…

Describes an application of methodology based on the Information Integration Theory to study intuitive mastery by 13-14 year-olds of Archimedes' Effect in physics. (Author/YP)

Describes a study of the understanding of basic electrical concepts shown by 15-17 year-old students in England, France, Netherlands, Sweden, and West Germany. Reports substantially the same pattern of learning difficulties across countries. Provides sample items. (Author/YP)

Most physics problem-solving studies provide data that indicate problem representation is different between experts and novices. This paper presents "cognitive aids" guiding the process of elaboration of a problem representation through intermediate representations. Intermediate means that the representation is situated somewhere between…

Examined the evolution of the knowledge and the notions of students in order to see how after one year of university study their concepts and ideas of scientific theory in chemistry had progressed. Reports that sometimes the students' conceptions are modified in the wrong way. (Author/YP)

Celebrates the 300th anniversary of "Principia Mathematica" written by Sir Isaac Newton. Reviews Newton's life and the circumstances which relate to "Principia." Relates the contributions of other scientists of Newton's time. Discusses Newton's life after the publication of "Principia." (CW)

Discusses how the reputation of "Principia" was created and maintained. Indicates the difficulties of identifying a single unambiguous meaning for the text. Shows that knowledge of Sir Isaac Newton makes little difference to understanding the later impact of the work. (CW)

Discusses the history of scientific thought in terms of the theories of inertia and absolute space, relativity and gravitation. Describes how Sir Isaac Newton used the work of earlier scholars in his theories and how Albert Einstein used Newton's theories in his. (CW)

Describes the Assessment of Performance Unit (APU) Science project. Discusses the findings including perceptions of problems, procedural understanding, control of variables, and measurement strategies. Suggests a change from traditional learning strategies to more student-centered ones. (YP)

Outlines the contents of Volume II of "Principia" by Sir Isaac Newton. Reviews the contributions of subsequent scientists to the physics of fluid dynamics. Discusses the treatment of fluid mechanics in physics curricula. Highlights a few of the problems of modern research in fluid dynamics. Shows that problems still remain. (CW)

Perspectives on the nature of subject matter in science are offered in this paper. It is proposed that science and its context are better viewed as shifting rather than remaining fixed. The rational, moral, and authentic nature of science is explained in reference to education in general and more specifically to the contexts of the science teacher…
