Gazing at the night sky is a familiar experience for many elementary students. Depending on where children live, they can often look out a window and see the Moon and stars. Children may have seen the Moon and stars in television shows, movies, posters, or children's picture books. Regardless of whether they see the Moon and stars firsthand or…

The American Association for the Advancement of Science (AAAS 1993) states that by the end of fifth grade, students should understand that a model, such as those depicting the solar system, is a smaller version of the real product, making it easier to physically work with and therefore learn from. However, for students and even adults,…

If one asked some friends where on the horizon they should expect to see the sunrise, half of the answers would be in the east. Of course, something analogous would happen with the sunset and the west. However, sunrise and sunset virtually never occur at these cardinal points. In fact, those answers correctly describe observations only during the…

Visualization is the art of turning information--concepts, processes, events, structures, and trends--into images that support our understanding. Carter Emmart is a visualizer of science. He is the director of astrovisualization for the American Museum of Natural History (AMNH). In this interview, Emmart describes what it is like to be a…

Citizen science projects provide non-scientists with opportunities to take part in scientific research. While their contribution to scientific data collection has been well documented, there is limited research on how participation in citizen science projects may affect their scientific literacy. In this study, we investigated (1) how volunteers'…

The U.S. has experienced a sharp increase in the number of bachelor astronomy degrees awarded in recent years with about twice as many degrees now being awarded than a decade ago. There were 385 astronomy bachelor's degrees awarded in the 2011-12 academic year. The number of astronomy PhDs awarded in recent years is up about 50% from a decade…

Relationships between sixth grade students' moon journaling and students' spatial-scientific reasoning after implementation of an Earth/Space unit were examined. Teachers used the project-based Realistic Explorations in Astronomical Learning curriculum. We used a regression model to analyze the relationship between the students' Lunar Phases…

"Great Explorations in Math and Science[R] (GEMS[R]) Space Science" is an instructional sequence for grades 3-5 that covers fundamental concepts, including planetary sizes and distance, the Earth's shape and movement, gravity, and moon phases and eclipses. Part of the "GEMS"[R] core curriculum, "GEMS[R] Space Science"…

In the present study, students' ideas concerning some basic astronomy concepts are investigated. One hundred and sixty-two Turkish students at different grades (from primary and secondary school levels) participated in this study. Data of the study were gathered using a test, which required participants to present their answers by both writing and…

Spotting the Moon in the sky is like finding a treasure--unexpected and beautiful. When children look for the Moon in the sky, they don't know where to look. The Moon is far away and most easily observed at a time when most young children are sleeping. Because direct contact isn't possible, adults have to be creative in how they help children…

Network for Astronomy School Education, NASE, is a project that is organizing courses for teachers throughout the entire world. The main objective of the project is to prepare secondary and primary school teachers in astronomy. Students love to know more about astronomy and teachers have the opportunity to observe the sky that every school has…

The rotational speeds of stars in the disc of a spiral galaxy are virtually independent of the distances of the stars from the centre of the galaxy. In common parlance, the stellar speed versus distance plot known as a galactic rotation curve is by observation typically nearly flat. This observation provides strong evidence that most galactic…

Previous empirical studies using multiple-choice procedures have suggested that there are misconceptions about the scale of astronomical distances. The present study provides a quantitative estimate of the nature of this misconception among US university students by asking them, in an open-ended response format, to make estimates of the distances…

This article introduces a set of distance education astronomy laboratory exercises for use by college students and instructors and discusses first usage results. This General Astronomy Education Source exercise set contains eight two-week projects designed to guide students through both core content and mathematical applications of general…

Continuing our work from a previous study (Coble et al. 2013), we examine undergraduates' ideas on the composition of the Universe as they progress through a general education astronomy integrated lecture and laboratory course with a focus on active learning. The study was conducted over five semesters at an urban minority-serving institution. The…
