Describes fourth graders' observations and hypotheses about the sun and moon and how the three-dimensional reality gradually replaced the inadequate two-dimensional models of textbooks. Discusses implications for instruction of this progression from concrete to abstract. (HTH)

Focusing on why the elliptical form in architecture is found only in the baroque period, discusses the development of the conic section and interactions in the baroque period with art, astronomy, and mathematics. An experimental approach to the topic carried out with high school seniors is reported. (Author/JN)

Native American science is defined as activities of native peoples of the New World in observing physical phenomena and attempting to explain and control them. Problems in studying native science, ethnoscience and native science, archaeostronomy and ethnoastronomy, ethnobotany, agriculture, technology, and future directions are discussed. (JN)

Reviews books for intermediate and older readers on astronomy, the history of computers, and geology. (CRH)

Discusses motions of the sun and earth in relation to the accuracy of clocks. Effect of eccentricity of the earth's orbit, efect of inclination of the earth's axis, and combination of these two effects are considered. The accuracy of sundials is also discussed. (DH)

Annotates six books dealing with (1) astronomy, (2) industry in space, (3) observation, (4) oceanography, and (5) robots. (FL)

Third- and fourth-grade students were taught about constellations using either a constellation star field only or a constellation star field with an overlay of mythological constellation figures. Written tests and planetarium tests showed no significant difference in scores between these two groups. (MLH)

Describes the purpose, inception, and services of the International Astronomical Union's Commission 46, which is composed of members from many nations who are interested in the teaching of astronomy. (MLH)

Discusses numerous aspects of science education, such as inquiry methods, research studies, the use of educational objectives, new curriculum projects, learning theories, and educational accountability. (MLH)

Discusses three alternatives to the traditional high horizon planetarium design: the tilted dome, the hyperhemisphere, and the minimum horizon design. (MLH)

Listed are resources and references for earth science teachers including doctoral research, new textbooks, and professional literature in astronomy, space science, earth science, geology, meteorology, and oceanography. (SL)

This booklet contains information and activities on the life cycle of stars. Materials can be adapted for kindergarten through grade 8 classrooms. Background information on massive stars and medium stars and activities with subjects such as star life, constellation shapes, nebula terminology, astronomical distances, and pulsars is included. The 12…

This study explored the mental components that are most important for successful problem solving. Four components were studied: cognition, metacognition, noncognitive variables, and justification skills. It was hypothesized that cognition and knowledge of cognition would predict success at solving well-structured problems, which have one correct…
