In this article, the authors present a new way of teaching the phases of the Moon. Through the introduction of a "self shadow" (an idea of a shadow that is not well-known), they illuminate students' understanding of the phases of the Moon and help them understand the distinction between the shadows that cause eclipses and the shadows that relate…

The typical "Astro 101" lecture-based course is passive, and adding well-designed learner-centered labs allows students to experience science as a pattern of thought. In this article, we present an approach to developing an introductory lab course. Identification of goals and student outcomes, particularly skills, and process and attitudinal…

The Astronomical Society of the Pacific (ASP) conducted a national survey of in-service teachers participating in Project ASTRO. The survey results document (1) the value that teachers place on supplemental astronomy education provided by professional and amateur astronomers, and (2) the difference that teachers perceive in the value provided by…

This study has examined the impact of teaching certain basic concepts of astronomy through a predict-observe-explain strategy, which includes three-dimensional (3D) computer modeling and observations on conceptual changes seen in sixth-grade elementary school children (aged 11-13; number of students: 131). A pre- and postastronomy instruction…

Astronomy was a required subject in the first American secondary level schools, the academies of the 18th century. When these were supplanted a century later by public high schools, astronomy still was often required, subsumed into courses of Natural Philosophy. Reasons given at that time to support astronomy as a part of general education include…

This article reports the findings from a study that examined how adolescent students with reading difficulties utilized cognitive tools that were embedded in a technology-based middle school science curriculum. The curriculum contained salient features of the Universal Design for Learning (UDL) theoretical framework. Sixteen general education…

This publication details the missions of Mariners 6 and 7 to the vicinity of Mars in the summer of 1969. Description is provided of the spacecraft, its preparation for flight, the 60 million mile journey, and the scientific results of the mission. There are numerous photographs including close-ups of the Martian surface. The content is narrative…

Part one recounted the story of the discovery of pulsars and examined the Crab Nebula, supernovae, and neutron stars. This part (experts from the book "Frozen Star") shows how an understanding of the nature of pulsars allowed astronomers to tie these together. (JN)

Examines mechanisms of how stars are formed in irregular galaxies. Formation in giant irregular galaxies, formation in dwarf irregular galaxies, and comparisons with larger star-forming regions found in spiral galaxies are considered separately. (JN)

Summarizes recent research on the formation of galaxies and clusters, focusing on research examining how the materials in galaxies seen today separated from the universal expansion and collapsed into stable bodies. A list of six nontechnical books and articles for readers with less background is included. (JN)

A Cornell University astronomer discusses teaching astronomy in schools and provides details on concepts such as the theorized black holes that may be apertures to distant galaxies and remote epochs. (Author/JA)

Students at Broward Junior College (Florida) are using the college's planetarium to study astronomy. The planetarium is the largest and best-equipped in Florida, and it ranks as one of the finest and largest college planetariums in the nation. (BB)
