This is a list of aerospace organizations and other groups that provides educators with assistance and information in specific areas. Both government and nongovernment organizations are included. (Author/SA)

This investigation focused on the stage of formal operational reasoning in the acquisition of astronomy concepts, and on efficacy of different instructional experiences for facilitating cognitive change in college students. Included are selected results and directions for future research. (SK)

Critiques Slusher's account of creationist cosmology, with occasional reference to other relevent creationist theories. Points out the fallacies and contradictions on seven topics, including the structure of the galaxies, Olber's Paradox, traveling of light in space, and changes in Saturn's rings. (DC)

The need to educate people about the sky as both a psychological and physical environment is discussed, including a formal curriculum schema (sky as habitat, sky as transport, influence on culture) and informal curriculum, with such topics as recreation, pollution, mythology, and clouds. (DC)

Describes the planning and construction of an observatory and a planetarium for a secondary school astronomy class by a science teacher with help from the school and from the community. (DS)

Provides an explanation and background material for the use of time lines to predict positions of five planets. (DS)

Described is an inexpensive and safe laboratory experiment that accurately duplicates the shapes and structures of simple impact craters using fireplace ash, finely ground charcoal, and an air gun. (Author/DS)

Described are several homework activities for use in teaching Astronomy. Topics include optical telescopes, the sun, and facts about the solar system. The format is a series of true-false questions related to diagrams which students must complete. (DS)

Presents the argument that the decline in Astronomy courses in secondary schools from 1894-1957 was caused by the Committee of 10 Report. This report emphasized the requirement of physics and chemistry for admission to college. Astronomy was considered an elective science course stressing direct observations and classroom instruction. (MA)

Presents a selection of Web-based reference resources in the earth and physical sciences, focusing in particular on geology, chemistry, physics, astronomy, and weather. Sites listed are those likely to be of broad interest, and most or all of the contents of the resources listed are available for free. (Author)

Describes an interdisciplinary unit on the environment and space travel in which students plan a fictional departure from Earth which is on the brink of destruction from environmental waste and neglect. Students travel through concepts in environmental education, math, art, English, and astronomy before reaching their destination with a clearer…

Describes a Star Party which involves comparing the different colors of the stars, demonstrating how astronomers measure the sky with degrees, determining the cardinal direction, discussing numerous stories that ancient civilizations gave to constellations, exercising science process skills, and using science instruments. (JRH)

Describes a study providing evidence of how students' talk and writing about the nature of science differs depending on the particular scientific topic under discussion. Describes the relationship between theory and evidence, warrants for belief, and nature of observation. (Contains 25 references.) (Author/YDS)

Described is a program which encouraged parents to become involved with their children in a science program at home. Discussed are the activities and organization of the program. A list of resources is provided. (CW)

Presented is an astronomy activity in which students use an apparatus to illustrate the various positions and movements of the sun, earth, planets, stars, and constellations. A test of the heliocentric theory of the solar system is included. (CW)
