Presents scientific explanations of primary colors and color mixing, black and white surfaces, the spectrum and the ability of the eye to distinguish color difference, the description of color, and the appearance and optical properties of metals. Contains 16 references. (Author)

Reviews the approaches presented in the Self-Paced Study of Strategies Useful for Solving Word Problems in the Physical and Biological Sciences that can be used by students to successfully solve word problems encountered in any entry-level science course. Describes the topics covered in five "study sessions" that allow the students to practice the…

Surveyed 7-year-olds' ideas about the Earth in space, focusing on their ideas about shape and their ability to represent and describe land masses or other surface features, Earth's size relative to the sun and moon, and its nature as a planet. Found that focusing on the Earth's shape and gravity alone has underestimated youngsters' learning…

Reports on an innovation in Swedish teacher training that is attracting students taking courses on interdisciplinary thematic topics. Notes that unqualified teachers are teaching in the science disciplines of physics, chemistry, and biology. Provides three years worth of statistics on the number of applicants and admitted students in teacher…

Advocates teaching as a research-based activity. Describes the national curriculum in English Schools and compares it with curricular development in New Zealand. Recommends inservice training (InSET) to ensure teachers' confidence in presenting scientific ideas. (Contains 25 references.) (YDS)

Recommends that inner city students (and essentially all high school students) be required to take physics. Lists some problems with teaching physics in inner city schools. (WRM)

Presents detailed instructions and teaching tips for demonstrating resonance and the resulting fracture in a wine glass. (WRM)

Describes the construction and use of a set of "relativistic metersticks" that represent the apparent lengths of a meterstick passing a stationary observer at relative speed v/c. (WRM)

Describes an experiment in which two semi-transparent reticles and a photographic plate separated by several centimeters are illuminated by a monochromatic point source in a typical in-line configuration that results in a hologram that contains information from both reticles. (Author/WRM)

Presents an activity that involves dropping spherical party balloons onto a sonic motion sensor to show that the force associated with the air resistance is proportional to both the square of the velocity and the cross-sectional area of the balloon. (Author/WRM)

Determines the extent physics textbooks contribute to physics teaching objectives and knowledge acquisition in Libya. Analysis of seventh- through ninth-grade physics textbooks and cognitive demand shows a limited effect of textbook content on knowledge acquisition and educational objectives. Suggestions are made for promoting the acquisition of…

Studies a teacher's role and actions in a science learning community. Interprets two teaching episodes that illustrate how the teacher helps a group of students transform their understanding of electrical circuits. Contains 26 references. (DDR)

Traces the evolution of physics teaching and research in Bucharest and Jassy, the two most important Romanian intellectual centers. Reports on three stages of historical development and selected biographies of Romanian scientists are included. (DDR)

Describes a procedure based on the assumption that during the rated lifetime of a light bulb roughly half of the radius of the filament evaporates. Explains how the filament's operating temperature can be deduced. (DDR)

Beneath elements of cognitive development, motivation is seen as a basic concept to describe students' learning in a physics classroom. German secondary school students regard physics as difficult to learn, very abstract, and dominated by males. Knowing about the influence of motivation on learning physics may lead to new insights in the design of…
