Trigonometric parallax is a powerful method to work out the distance of celestial bodies, and it was used in the past to measure the distance of the Moon, Venus, Mars and nearby stars. We set up an observation campaign for high school and undergraduate students with the purpose to measure both the Moon's and Mars' parallax. To have a large enough…

In this article, we briefly outline and discuss the legal and ethical ramifications of doing astronomy education research, with an emphasis on the practical issues that researchers have to keep in mind when engaging in, and publishing about, research that involves human subjects.

Students at Copiah-Lincoln Community College (Co-Lin) have been hesitant to take courses in the physical sciences, mostly because of a lack of exposure to them in K-12 or a bad experience in this area. The college is addressing this need by exposing students to the physical sciences early on in their education. The science division at Co-Lin has…

In earlier columns, the celestial coordinate system of hour circles of right ascension and degrees of declination was introduced along with the use of an equatorial star chart (see SFA Star Charts in Resources). This system shows the planets' motion relative to the ecliptic, the apparent path the Sun follows during the year. An alternate system,…

The "National Science Education Standards (NSES)" state that students in grades K-4 are expected to understand that astronomical objects in the sky, including the Sun, Moon, and stars--have properties, locations, and patterns of movement that can be observed and described. They further suggest using an inquiry-based approach to teach…

The research reported here documents scientists' changing practices and attitudes concerning college teaching. Graduate students and postdoctoral scientists participated in long-term, inquiry-based teaching professional development while maintaining an ongoing commitment to research science. Data analysis focused on digital recording and…

During the past few decades, researchers from a cognitive science tradition and a sociocultural perspective on learning have discussed how to understand students' conceptions of the earth. In this article, some of the questions discussed in this debate are elaborated in relation to meaning making in educational settings. The aim is to illustrate…

As an astronomy instructor, I am always looking for commonly observed Earthly experiences to help my students and me understand and appreciate similar occurrences elsewhere in the solar system. Recently I wrote a short TPT article on frost. This paper is on the related phenomena of precipitation. Precipitation, so common on most of the Earth's…

We adopt the Web 2.0 paradigm as a mechanism for preparing, editing, delivering and maintaining educational content, and for fostering ongoing innovation in the online education field. We report here on the migration of legacy course materials from "PowerPoint" slides on CD to a fully online delivery mode for use in the "Swinburne Astronomy…

The present article describes some activities performed with high-school students in the "Solar Physics" course developed in a Brazilian science centre. The topics of chemical composition, temperature and stellar evolution were taught in a room totally dedicated to study of the Sun, a solar room, designed with simple and inexpensive…

This article describes a paper-and-pencil construction to determine and graphically depict with reasonable accuracy the times and azimuths of sunrise and sunset on any day of the year at any location on Earth. The construction requires, as input, a date (or the sun's declination) and the latitude and longitude of the location in question, and one…

The realtionship between astrologers and their believing clients is probed. (CK)

A 2007 nationwide mixed-methods survey of high school astronomy teachers reports on its current characteristics and its changes over intervening decades that included the introduction of standards and the No Child Left Behind Act (NCLB). Some changes found include section enrollments trending downward even while the total number of courses offered…

The current article represents a methodological proposal. It seeks to address the question of how one might recognize a discovery as a discovery without knowing in advance what is available to be discovered. We propose a solution and demonstrate it using data from a study previously reported by J. Roschelle (1992). Roschelle investigated 2…

Educators can connect their students internationally in meaningful activities that address multiple teaching standards that are of concern to educators, parents, and the public worldwide. In this article, the authors describe a project wherein Australian Year 7 students made an "Edible Lunar Vehicle" (ELV) together with U.S. college…
