Provides examples of large Internet sites that act as clearinghouses for information on hypertextbooks. (AEF)

Suggests a way of teaching science to young children that is consistent with Piaget's interpretation of the child's spontaneous animism and that elicits a personal and in-depth response to knowledge. Describes construction and use of an environmental bubble to enhance children's interest in the night sky. (SW)

Presents a simple, graphical method for tracking the apparent motion of the Moon through a seven-day phase. Describes the necessary equipment, and the daily procedure for making observations. Includes suggested open-ended questions along with an appropriate reference. (JJK)

Presents basic facts about quasars as most powerful sources of radiation in the universe. Describes in detail the mirages and illusions that quasars generate and methods for their interpretation. Includes the notion of the gravitational lens and its relationship to twin quasars and the apparent measure of a quasar's bright jet tail moving faster…

Describes the genesis, the early experiments, and the limitations of X-ray astronomy. Discusses original methods for searching and locating the first interstellar X-ray source, modern attempts to identify a massive black hole as part of a binary system X-ray source, and the effort to generate X-ray images of solar flares. (JJK)

An extensive observational project of the movement of the moon is described. Directions for building a cross-staff used to measure the angle between specific stars and the moon and a copy of a stereographic projection of the celestial sphere used in data reduction are provided. (KR)

Described is the undergraduate curriculum in physics and its relationship to astronomy at Cambridge University. Discussed are the astronomical research and research establishments at Cambridge. Personal views of a student on the postgraduate research being done at Cambridge are also included. (KR)

An educational technique to calculate the lifetime of a comet using software-generated random numbers is introduced to undergraduate physiques and astronomy students. Discussed are the generation and eligibility of the required random numbers, background literature related to the problem, and the solution to the problem using random numbers.…

Explains the importance of discussing women scientists in science instruction. Describes the life and work of Rachel Carson (1907-64), Annie Cannon (1863-1941), Estelle Ramey (1913-), and Chien Shiung Wu (1912-). (PR)

Presents an analysis of an astrophysics institute designed for high school students. Investigates how students respond cognitively in an active science-learning environment in which they serve as apprentices to university astrophysics professors. (Author/CCM)

Describes the organization and completion of a scientific field trip for a group of high school physics students that was organized primarily around a study of the Manhattan Project. The group visited the Trinity site, Los Alamos, several museums, and the National Radio Astronomy Observatory Very Large Array. Contact information for the various…

Describes an introductory astronomy course designed for non-science majors. Uses the project-based learning approach and requires students to construct 3-D models for three astronomical phenomena. (YDS)

Asks if literature can open up and revitalize the scientific study of astronomy in elementary classrooms. Reviews the author's personal thinking and exploration that led to bringing science and literature together in powerful ways. Discusses how scientific principles can be embedded in a rich foundation of literature and student inquiry. (SG)

Demonstrates a model system that recreates seasonal processes on Mars. Lists necessary materials and explains the construction of the demonstration. Provides discussion questions. (Contains 11 references.) (YDS)

Reports on a study designed to measure changes in students' science proficiency produced by a multimedia learning environment. Describes the inquiry-based design of Astronomy Village, which supports middle school students in learning fundamental concepts in life, earth, and physical sciences. Results indicate sizable treatment effects for two…
