Errors in the teaching of the concepts of Charles's Law are traced back through history to a major French physics text published in 1816. Relevant original sources are quoted and remedies are suggested. Five major criticisms are summarized. (Author/CW)

A questionnaire and demonstrations were used to identify students' conceptions about the composition of orthogonal velocities. Four questions from the questionnaire are provided and the results for each question are reported. The four implicit vector characteristics of this study are appended. (YP)

Stresses the importance of a reference frame in mechanics. Shows the Galilean transformation in terms of relativity theory. Discusses accelerated reference frames and noninertial reference frames. Provides examples of reference frames with diagrams. (YP)

Replies are given to students' complaints about their physics textbook, "PHYSICS, Principles and Problems" (Merrill, Bell & Howell). Indicates wrong answers to some of the problems in the book. Discusses several topics identified by the students. (YP)

Provided are two demonstrations for an introductory course in chemistry. The first one emphasizes the observation and the interpretation of facts to form hypotheses during the heating of a beaker of water. The second demonstration shows the liquid phase of carbon dioxide using dry ice and a pressure gauge. (YP)

Provides an introduction and explanations of stress-strain relationships, measuring stress, a goal of structural analysis, and legitimate applications of the concept of stress. Diagrams include a derivation of the stress tensor, graphical representations of stress-strain relations, and related problems. (RT)

Examines the possibility that part of the problem in the teaching of physical science may lie in teaching-learning materials. Selects 14 chemistry textbooks and 14 physics textbooks in Australia. Analyzes them based on learning theory and scientific literacy. (YP)

The results of survey of secondary school biology students used to access misconceptions about cells are presented. A distinction between conceptions, misconceptions, and nonconceptions is drawn in terms of secondary school biology concepts. The resilience of misconceptions is discussed. (CW)

Describes the discoveries by Hertz historically, such as photoelectric effect, radio waves, their impact on modern physics and some applications. Presents several diagrams and two chronological tables. (YP)

Introduces a low-cost protein-testing technique using gel electrophoresis. Describes materials, manufacturing method, and experimental method. (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)

Describes a biology course to meet the needs of nontraditional students. Included is information on the course including the needs, beginnings, framework of basic concepts with a multisensory approach, and course objectives. Reports the data showing student success. (YP)

Wheatley's 1992 bestseller, "Leadership and the New Science," argues that across scientific disciplines, our rational, systematic quest for order, control, stability, and predictability are yielding to a deeper appreciation for chaos, complexity, uncertainty, and change. In this interview, Wheatley shows how breakthroughs in biology,…

Reports results of interviews and tests carried out with students after they had been taught the topic of evolution. Different interpretations of Charles Darwin's theories are also analyzed. Results revealed that students show a poor understanding of evolutionary theories. (ZWH)

Describes how students in a geoscience course are introduced to geographic information systems (GIS), a computer-assisted system for the acquisition, storage, analysis, and display of geographic data, through a practical experience involving collecting data and inputting it into a GIS program called IDRISI.
