This theoretical paper introduces a new way to view and characterize learning astronomy. It describes a framework, based on results from empirical data, analyzed through standard qualitative research methodology, in which a theoretical model for a vital competency of learning astronomy is proposed: "reading the sky," a broad description…

The inherent spatial complexity of the human cerebral ventricular system, coupled with its deep position within the brain, poses a problem for conceptualizing its anatomy. Cadaveric dissection, while considered the gold standard of anatomical learning, may be inadequate for learning the anatomy of the cerebral ventricular system; even with…

Explains how to construct a three dimensional model for stereographic projection. It will be suitable for presenting the symmetry of crystal systems, and will help physics students understand the nature of crystallography. (GA)

Describes experiments which focus on the perception of three dimensions. Discusses the cues about distance and depth and the role they have in perceptions of three dimensions. Evaluates the effect of color on the illusion on depth. (ML)

Describes some of the capabilities of the Apple Macintosh computer in constructing stereo pairs for three-dimensional viewing. Discusses various software packages which can produce the desired graphics. Provides examples of how to use these stereo images in geology, chemistry, and psychology. (TW)
