The past several years have presented the astronomy education research community with a host of foundational research dissertations in the teaching and learning of astronomy. These PhD candidates have been studying the impact of instructional innovations on student learning and systematically validating astronomy learning assessment instruments,…

Electronic classroom response systems (CRSs) have been in use in large college lectures for over three decades. Such systems are designed to provide instructors and students with immediate statistical analyses of student electronic responses to multiple-choice questions posed to the class by the instructor. The technique known as peer instruction…

This article reports the findings of a study examining independent variables that contributed to the science, technology, engineering, and mathematics (STEM) achievement of students with reading difficulties who participated in a technology-enhanced astronomy curriculum.

The phenomenon of tides has a faraway source. This rise and fall of the water level over a period of several hours is a result of the gravitational pull of the Moon and the Sun on Earth's oceans. Tides exhibit predictable cycles on daily, monthly, and yearly scales. The magnitude of the tides is dependent on the position of the Earth and Moon in…

On 8 June 2004 Venus will pass in front of the Sun as seen from the Earth. Many people will watch the small dark dot cross the solar disk, but will they stop to think about Venus as a real place? In this article we discuss what we know about Venus, what it looks like from orbit, what you might see if you were on the surface and future plans for…

Teaching Romer's discovery alongside the Doppler effect can reveal a satisfying linkage between the two and give students a better understanding of both than they get from studying either alone.
