New Ranking Task Editor

As part of our transition from Flash to HTML we have made an online editor to create interactive ranking tasks. These HTML-based ranking tasks work on both PCs and mobile devices. Ranking tasks are created in the browser simply by importing images and filling out a few text fields.

The new editor is found on the Interactives page. This page also has links to example ranking tasks, as well as a video demonstrating how they were made.

Registration Opens for October 6th Workshop

All high school and college instructors of physics and astronomy are encouraged to attend the fall 2018 Astronomy Education Workshop (held jointly with the biannual meeting of the Nebraska Chapter of the American Association of Physics Teachers). Attendees can attend two large group presentations and choose four 30-minute breakout sessions (from among 16 choices) and a 90-minute hands-on session (from among 3 choices). The event is free and includes continental breakfast, lunch, a chance in a door-prize raffle, and UNL parking is covered.

Breakout Sessions are being scheduled for October 6th Workshop

Finalizing the schedule and promotion of the October 6th Workshop continues. This will be a joint Astronomy Education Workshop (the 17th) and biannual meeting of the Nebraska Chapter of the American Association of Physics Teachers. Educators who are interested in leading a breakout session for the meeting are encouraged to contact Kevin Lee at

Breakout sessions are 28 minutes in length. They can be about a particular content item, an issue surrounding our community, or a teaching technique, pedagogy, or instructional technology in either Astronomy or Physics (or related fields chemistry, geology, etc.). They must be interactive -- this is not a talk! Ideas may be gleaned from looking at the schedule from the last workshop.

New Videos Posted

Two new astronomy demonstration videos were posted recently:

  • Optics 1: Reflection -- which explores the applications and underlyig physics of corner-cube-reflectors.
  • The Tidal Heating of Io -- which explores how differential gravity and the elliptical orbit of Io give rise to volcanism
