New in 2019: Online Interactives Editor

As part of our Flash to HTML transition we have made an online editor for ranking tasks.

Launch the Interactives Editor in a New Window

The editor is still in the early stages of development. We are sharing it now in the hopes that some will find it useful. The demonstration video below shows how to use the editor to create ranking tasks.

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.

The materials above are collectively the work of David Hudgins (Rockhurst University), Kevin Lee (University of Nebraska), and Edward Prather (University of Arizona). They may be used freely for any non-profit educational purpose – other uses require permission. Contributions to the programming were made by Renee Augustyn, Andy Frederick, Keith Nickum, and Chris Siedell. The work is supported by an NSF grants nos. 0737376 and 0715517, a CCLI Phase III Grant for the Collaboration of Astronomy Teaching Scholars. (CATS).
