This is a report of an activity of introduction to the study of astronomy developed with a group of future physics teachers at a Brazilian public university. Such activity had the goal of giving privileged emphasis to notions of spatiality, alternative conceptions of the participants, and the process of interaction among peers, with the objective…

The precession rate of the Earth-Moon system by the gravitational influence of the Sun is derived. Attention is focussed on a physically transparent but complete presentation accessible to first- or second-year physics students. Both a shortcut and a full analysis are given, which allows the inclusion of this material as an example of the physics…

In China, "Space Science" and "Our Place in the Universe" form part of the geography syllabus. Such cultural challenges are part of the everyday intellectual gymnastics necessary to sustain European-Chinese school collaborations. Belle Vue Girls' School in Bradford has an ongoing collaboration with Chang Zheng Secondary School…

By means of a simple device, made by students themselves, the movements of the Sun and the Moon can be studied at different latitudes. Using this device, it is easy to explain phenomena such as the midnight Sun, zenith pass and why the Moon "smiles". In this article, we show various photos of the Sun's movements, alongside their simulations on the…

The purpose of this paper is to describe and analyze the process of construction of meaning about the shape of the Earth and the alternation of day and night, which is inherent to the practice of experimental science teaching. This teaching practice was gradually done by the researcher in a 1st grade class of a Portuguese primary school. The class…

One of the long-standing general undergraduate education requirements common to many colleges and universities is a science course with a laboratory experience component. One of the objectives frequently included in the description of most of these courses is that a student will understand the nature and processes of scientific inquiry. However,…

What's wrong with the sustainability movement, the author contends, is the uncritical homogenization of humanity. Sustainability advocates inevitably seek to homogenize people's deepest values, because their goal is to save Earth from ecological, economic, and social disaster. Everyone must participate--everyone must share the same key values and…

An instrument designed to measure a 3-factor model of research motivation was developed and psychometrically examined in the present research. Participants were 437 graduate students in biology, chemistry/biochemistry, physics/astronomy, and psychology. A principal components analysis supported the retention of 20 items representing the 3-factor…

This study explored young children's understandings of targeted lunar concepts, including when the moon can be observed, observable lunar phase shapes, predictable lunar patterns, and the cause of lunar phases. Twenty-one children (ages 7-9 years) from a multi-aged, self-contained classroom participated in this study. The instructional…

This study reports the results of the first systematic investigation into Astro 101 students' conceptual and reasoning difficulties with cosmology. We developed four surveys with which we measured students' conceptual knowledge of the Big Bang, the expansion and evolution of the universe, and the evidence for dark matter. Our classical test theory…

This mixed methods study described preservice teachers' conceptions of tides and explored the efficacy of integrating online data into inquiry-based instruction. Data sources included a multiple-choice assessment and in-depth interviews. A total of 79 participants in secondary, middle, and early childhood teacher education programs completed the…

"Reading, Writing, and Rings!" was created by a team of elementary teachers, literacy experts, and scientists in order to integrate science and literacy. These free units bring students inside NASA's Cassini-Huygens mission to Saturn. The authors--a science teacher and education outreach specialist and two evaluators of educational programs--have…

The nature of expertise in astronomy was investigated across a broad spectrum of ages and experience in China and New Zealand. Five hypotheses (capable of quantification and statistical analysis) were used to probe types of expertise identified by previous researchers: (a) domain-specific knowledge-skill in the use of scientific vocabulary and…

The Star Properties Concept Inventory (SPCI) is among the first instruments made available to assess student gains in a major section or "unit" of a traditional introductory astronomy course, in this case the unit on stars. This is in contrast to instruments for an entire course, such as the Astronomy Diagnostic Test or the Lunar Phases…

There's no better way to celebrate 2009, the International Year of Astronomy, than by curling up with a good book under summer skies. To every civilization, in every age, the skies inspired imagination and scientific inquiry. There's no better place to start your summer reading than under their influence. Here are a few selections identified by…
