Literacy remains an area of concern in early secondary education in Scotland (ages 12-14), with recent research suggesting a continued decline in attainment levels. As literacy underpins learning, interdisciplinary and collaborative approaches to teaching literacy are now being emphasized through the new Curriculum for Excellence that aims to…

In a previous paper submitted to the Demonstrations section (Birriel 2008, "Astronomy Education Review," 7, 147), I discussed using commercially available incandescent light bulbs for the purpose of demonstrating absorption spectra in the classroom or laboratory. This demonstration solved a long-standing problem that many of astronomy instructors…

We analyse the motion of a spot of light projected onto a flat screen by a rotating source. We find that the motion of the spot has many interesting features such as spot splitting and superluminal effects. Our discussion is well suited for undergraduates and can be an interesting add-on in their curriculum, giving them new insights into the…

"Ozone" is a sensitive topic that arouses interest everywhere. Its presence in the stratosphere affects us all, and its threatened reduction would have such dire consequences that it energizes international campaigns, influences the thinking of governments, and activates substantial alterations in the accustomed habits of millions throughout the…

In problems dealing with the Earth's gravity, students are frequently bewildered by the fact that the two common expressions for potential energy, "mgh" and "-Gm[subscript e]m/r", differ in sign and differ considerably in form. Some textbooks demonstrate that the more familiar first expression is a special case of the more general second equation…

This note describes how white light interference fringes can be seen by observing the Moon through a double-glazed window. White light interferometric fringes are normally observed only in a well-aligned interferometer whose optical path difference is less than the coherence length of the light source, which is approximately one micrometer for…

At the Smithsonian, big questions are the common denominators that unite their museums, research centers, and programs. And curiosity is contagious. Today's small child who looks in awe at the big dinosaurs that once roamed the earth and wonders, "What happened?" might just be tomorrow's paleontologist. Among this year's stories is a…

This study aims to identify the way upon which ICT can be employed in science teaching to develop scientific literacy level. The study has conclude to design a triple learning model (PEA) based on ICT and constructive learning strategy in teaching science through a context which cares for building positive trends of searching for knowledge and…

This qualitative case study describes (a) the ways 3D visualization, coupled with other science and literacy experiences, supported young children's first exploration of the Earth-Sun-Moon system and (b) the perspectives of classroom teachers and children on using 3D visualization. We created three interactive 3D software modules that simulate day…

Over the past 15 years, professional astronomers, their societies, and associated funding agencies have collaborated to improve astronomy teaching and learning at the introductory undergraduate level. Many nonscience majors and preservice teachers enroll in these introductory astronomy courses, thus meriting the focused attention. In this review…

Twenty-nine Zulu-speaking primary school teachers were enrolled for a certificate in-service science education course. Initially, informal classroom discussions with these teachers pointed out poor conceptual knowledge in basic astronomy. This study investigated teachers' scientific and indigenous conceptions of the Earth-Moon-Sun (E-M-S) system,…

Researchers have shown that most students resist changes to their core beliefs by offering auxiliary hypotheses at the first sign of the development of conceptual change. Studies have viewed student reaction to discrepant events as an important clue in helping researchers understand not only the structure of alternative concepts (Niaz,…

The Statistical Research Center of the American Institute of Physics conducts an annual census from October through February of all 75 departments that offer degrees in astronomy in the United States. For the class of 2008, the authors received responses from 73 (97%) of these departments. Estimates were derived and included in the totals for…

For thousands of years before the invention of reliable clocks, humans measured their days by the motion of the sun. Astronomically, one day was the length of time it took for the sun to return to the same position in the sky. With the advent of precise mechanical chronometers such as Harrison's timekeepers (Sobel and Andrewes 1998), which ran at…

This longitudinal study examined the acquisition of early knowledge of astronomy to determine whether children's knowledge at any point in time is consistent with a naive "mental model." Children were first assessed by means of open questions and drawing tasks at 2 and 3 years of age (N = 143). The knowledge was reassessed over the course of the…
