Demonstrates the relationship between the metaphor and the language of the social sciences, with particular reference to anthropology. (AM)

Analyzes the concepts of physical time and of the measurement of the magnitude of time, and examines the International System of Units (SI). A proposal for the use of the Einstein system (ES) is also included. (HM)

Discusses the principles behind holograms: the design and procedure to make either a reflection hologram or a transmission hologram, developing the hologram, safety precautions, and classroom applications. (JRH)

Highlights some National Science Board's science and engineering indicators that confirm that those who teach college-level science appear to be doing something right. Presents ideas about how they can continue to improve. (JRH)

Presents an activity that uses holiday lights to help students internalize the concept that white light contains a combination of all the colors of the rainbow. (JRH)

Discusses the role of quantum mechanics in high school chemistry textbooks. Attempts to coordinate the presentation of theory with the empirical evidence that supports it. Lists empirical generalizations and observations explained by quantum mechanics and exercises that require quantum mechanics to explain or predict phenomena in typical high…

Describes an experiment that uses air to test Charles' law. Reinforces the student's intuitive feel for Charles' law with quantitative numbers they can see, introduces the idea of extrapolating experimental data to obtain a theoretical value, and gives a physical quantitative meaning to the concept of absolute zero. (JRH)

Uses Tazo discs to construct and investigate spinners and discuss how teachers and students worked and thought, scientifically and technologically, during the investigation. Includes some literature links and a professional development opportunity. (Author/NB)

Discusses Mission Possible, a problem-solving strategy that provides a wide range of learning experiences and encourages students and teachers to explore the use of scientific ideas and principles. Describes setting up a Mission Possible Day for primary students in a rural community. (Author/NB)

Investigates the origins of the universal gas constant R and presents an historical perspective. (SOE)

Discusses the dilemma between evolution and creationism in biology teaching. Explains the position of the Louisiana House Education Committee and presents an example from the Louisiana State University (LSU). (Author/SOE)

Presents a strategy that enables students to: effectively reflect on the information they are learning; to identify scientific interconnections between individual facts and concepts; and to develop a system of conclusions. Explains that a concept network is a set of ideas and facts relating to a particular topic, with the linkages between facts…

Identifies behaviors of young children during play on swings that may be consistently observed as evidence of their construction of the physics principles related to pendulums. Findings indicate that children's activities on swings demonstrate their interest in experimenting with balance, force, gravity, resistance, and resonance. Discusses…

Presents methods for growing crystals in the classroom. Includes alum crystals, salt crystals, and sugar crystals. (JRH)

Explores students' conceptual understanding and conceptual growth in classical mechanics in the natural context of a grade 10 science classroom. Findings indicate that students' knowledge structures remained stable across the 10 weeks and remained unchanged 4 weeks after instruction ceased. Contains 30 references. (Author/JRH)
