Describes an Italian project designed to prepare elementary teachers to teach science by helping them understand basic physics concepts and realize the importance of considering students' conceptions in the teaching process. A practicum-based strategy, requiring that teachers carry out experimental activities designed for students is recommended.…

Some common themes of cartoons that use science as a subject are identified. Cartoons that deal with the topics of theory, the universe, school, the relationship between science and technology, and the nature of science are included. The sociology of scientific humor is discussed. (KR)

Describes the history of Richard Blakemore's discovery of magnetotaxic organisms. Discusses possible reasons why the magnetic response in bacteria developed. Proposes research experiments integrating biology and physics in which students investigate problems using cultures of magnetotaxic organisms. (MDH)

Based on the example of the history of the photoelectric effect as a case in teaching introductory quantum theory, it is argued that the dilemma between "historical truth" and "didactic usefulness" may be circumvented by focusing on a few, carefully selected case studies. The early introduction of the light-quantum is…

Presents thought experiments and science activities for helping students think about quantum mechanics and the idea of randomness. (PR)

Presents a program for elementary teachers to learn how to use hand tools and household appliances to teach the principles of physics. The lesson helps teachers become familiar with simple hand tools, combat the apprehension of mechanical devices, and develop an interest in tools and technology. Session involves disassembling appliances to…

Addresses some basic aspects of Archimedes' law. Focus is on potential energy relationships so as to elucidate some common misunderstandings and to facilitate making bridges with other physical topics. A spreadsheet model is used as a simulation tool. (Author/NB)

Reviews research on children's ideas about floating and sinking. Describes the Model-Assisted Reasoning in Science (MARS) project curriculum and student responses to a question about helium balloons. Contains 61 references. (DDR)

Summarizes research into how children perceive three-dimensional objects. Focuses on the difficulty that students have in appreciating how the orientation of the semicircular canals affects balance and space perception. (DDR)

Describes a procedure developed by students that measures the mass concentration of particles in a polluted urban atmosphere. Uses a portable fan and filters of various materials. Compares students' data with official data. (DDR)

Reports on research that aimed to establish whether patterns of students' reactions to and achievement on physics assessment tasks were associated with the format of the task and the absence or presence of real-world contexts in the tasks. Contains 21 references. (DDR)

The Hands-On and Far-Out Physics project is part of the Center for Technology, Environment, and Communication (C-TEC), a project-based learning community at Piner High School in Santa Rosa (California). This article introduces the project team, discusses member activities, presents a walking-speed experiment, and describes a Mars Colony course…

Describes procedures for a demonstration that features an exploding can. This demonstration prompts students to critically analyze the release of energy in an exothermic reaction, the work done in such a reaction, and the enthalpy. (DDR)

Examines the attitudes of physics instructors on how and when students should be allowed access to textbook problem solutions. Presents a detailed analysis of 249 survey responses from U.S. and Canadian universities which conveyed a wide range of opinions and comments. Discusses the need to rethink strategies regarding access to solutions. (AIM)

Takes a situated-cognition perspective on learning and cognitive development. Presents a detailed framework that includes operationalizations for levels of situated learning. Contains 31 references. (DDR)
