Astronomy Interactives

This site provides ranking tasks for teaching introductory astronomy. Pencil-and-paper versions as well as computer-based versions are available grouped by topic. New materials will be added as the computer-based versions are completed. It is anticipated that the pencil-and-paper versions will be photocopied for students and either used in the classroom or assigned as homework. The computer-based versions are intended as formative assessment tools to be used by students outside of class and have considerable utility in distance education courses.
