Describes the evolution of an introductory astronomy course from fact driven to concept driven. Presents a rationale for a course designed to engage students in considering answers to the questions "what are we?" and "how do we know what we know?" (DDR)

Uses role-playing exercises as a method for teaching introductory astronomy classes to nonscience majors. (CCM)

Introduces the analemma, a figure eight pattern of the sun's location over the course of a year. Presents a year-long science activity and explains procedures for indoor and outdoor models. (YDS)

Explains a non-standard definition of an ellipse familiar to astronomers and workers in celestial mechanics but which is not usually given in undergraduate text books on mathematics. (MM)

While there is frequent talk of integrating science with mathematics, and more recently, science with literacy, the author has always felt that at the elementary level there is more overlap between social studies and science. Mathematics and literacy share essential skills with science (e. g., measurement and data collection, observation and…

This is another great month for evening observing as four planets continue to remain easily visible. Venus, Mars, and Saturn can be viewed over the western horizon, and Jupiter is shining high over the southeastern horizon. Opportunities will also exist for using binoculars or low-power telescopes to observe conjunctions between the planets, the…

While trying to explain to his seventh grade students why models are needed to study science, the author stumbled across this project idea. At the time, his class was just beginning to study geology and rocks and minerals. This unit starts by introducing the structure of the Earth so students had very little background knowledge. He wanted a quick…

Since 1995, astronomers have discovered over 100 known exoplanets--planets outside of the solar system--and determined their properties such as mass, orbital distance, size, and density. By using simple algebraic equations of physics, students can determine these properties as well. In this article, the author discusses an activity titled…

Foucault's pendulum exhibition in 1851 occurred in an era now known by development of the theorems of Coriolis and the formulation of dynamical meteorology by Ferrel. Yet today the behavior of the pendulum is often misunderstood. The existence of a horizontal component of Newtonian gravitation is essential for understanding the behavior with…

For a long time, the medieval university maintained relative consistency throughout Europe in teaching topics and methods. But between 1550 and 1650 this came to an end. The evolution concerned the content of the courses and, to a lesser extent, the way the field was taught. The impact of these changes varied greatly from place to place, and new…

Since 1998, I've been experimenting with the use of role-playing games to teach astronomy. Students play the role of competing teams of researchers, racing to solve some astrophysical mystery. In this article, I review what has been learned from using these games around the world over the last eight years. The most common problem encountered is a…

The effective evaluation of educational projects is becoming increasingly important to funding agencies and to the individuals and organizations involved in the projects. This brief "how-to" guide provides an introductory description of the purpose and basic ideas of project evaluation, and uses authentic examples from four different astronomy and…

As an instructor in courses for prospective teachers, I am interested in my students' ideas and ways in which they reconstruct their ideas in conversations about science. In the case study presented here, I reflect upon (a) ways in which I engaged prospective teachers in thinking together about their observations of a natural phenomenon, the…

In June of 1974 the author volunteered to lead a travel group--a mixed-aged group of 21 people--to Communist China. Back in her halcyon college days she stumbled upon a course "Group Dynamics." At the time, she could not know its impact on her in her future role as a leader of travel groups. "Group Dynamics" placed…

The SETI Academy Planet Project provides an exciting, informative, and creative series of activities for elementary students (grades 5-6) in these activities each student plays the role of a cadet at the SETI Academy, a fictitious institution. This unit examines the evolution of stars and planets which is an important aspect of the search for…
