The Classroom Astronomer is a full color, quarterly, print, PDF and Apple Newsstand publication designed as a practitioner journal for classroom teachers of astronomy. While centered at the high school level, it also provides tips, techniques and informative how-to articles for teachers of grades K-8 and undergraduate college "Astro 101" courses. Our mission is to increase the amount of astronomy in the school systems and improve the skills of teachers.
