A way for students to refresh and use their knowledge in both mathematics and physics is presented. By the study of the properties of the "Runge-Lenz" vector the subjects of algebra, analytical geometry, calculus, classical mechanics, differential equations, matrices, quantum mechanics, trigonometry, and vector analysis can be reviewed. (KR)

Proposed is a method of learning about relevant aspects of a research scientist's work by analyzing "real" data. The way in which students used real data from an astronomy project is described. The procedures for the analysis and evaluation of the end results are included. (KR)

Presents two methods to teach the phases of the Moon: (1) students use a Styrofoam ball (Moon), light bulb (Sun), and one's own head (Earth) to model the Earth-Moon-Sun system; (2) students use their hands to represent the location of the Sun, Earth, and Moon during a teacher controlled "Moon Dance." (MVL)

Describes an activity that allows students to develop their own animated models that depict the orbits of the earth and the moon. (ZWH)

Describes a six-week project, in which students ground their own mirror, built a working telescope, and learned how and why it all works. (PR)

Suggests activities that could be incorporated into a study and actual viewing of a total solar eclipse, including student involvement in real research projects. Lists related websites. (Author/WRM)

Describes a simple model that illustrates concepts about time and its relation to terrestrial longitude. The model also simulates the diurnal motion of the sun and moon and their changing positions against the background stars. (Author/WRM)

Argues that, to revitalize undergraduate education in astronomy, courses must be restructured, particularly at the introductory level. Suggests that the culture of higher education does not often support change. (DDR)

Discusses how to develop teacher subject knowledge for effective delivery of the program of study at the primary level. Indicates that providing teachers with the necessary skills and confidence is complex. Contains 27 references. (DDR)

Introduces the Meteor Scatter Project (MSP) in which high school students build an automated meteor observatory and learn to monitor meteor activity. Involves students in activities such as radio frequency survey, antenna design, antenna construction, manual meteor counts, and computer board configuration and installation. (YDS)

What Australia, Alaska, Qatar, Indiana, and Ohio have in common is the authentic writing More Observations Of Nature (MOON) project. In this unique project, teachers from these disparate geographic locations teamed up to instruct children in grades four through eight via the internet on a nearly universally challenging subject for teachers in the…

These longitudinal studies investigated the cultural mediation of children's thinking about the Earth using an interview technique designed to elicit responses from children from all "levels" of their conceptual organization (intuitive, cultural, and scientific). Close scrutiny of the research literature in this field reveals that some…

We describe a project for calculus and differential equations students involving trajectories of a spacecraft whose propulsion system depends solely on muting gravitational effects of heavenly bodies. In particular, we consider the spacecraft imagined by H. G. Wells, and focus on getting his spacecraft from the Moon to the Earth. Cavorite, angular…

An experiment investigated how methods of questioning affect children's responses regarding the shape of the earth and the day/night cycle. Seventy-two children from Grade 1 and Grade 3 in a middle-class elementary school in Athens, Greece, were tested either by an open method of questioning or by a forced-choice method of questioning. The two…

The purpose of this study was to describe how three primary teachers attempted to overcome incomplete content knowledge when teaching an astronomy unit. Daily observations of science activities were videotaped and transcribed from each classroom to determine the influences on the changes in teacher and student ideas of astronomy. Teachers' ideas…
