P-dog's blog: boring but important

Astronomy and physics education research and comments, field-tested think-pair-share (peer instruction) clicker questions, flashcard questions, in-class activities (lecture-tutorials), current events questions, backwards faded scaffolding laboratories, Hake gains, field-tested multiple-choice and essay exam questions, indices of discrimination, presentation slides, photos, ephemerae, astronomy in the marketplace, unrelated random sketches and minutiae.

GIF animation: distant star versus nearby star parallax

Distant star, smaller parallax angle.

Nearby star, larger parallax angle.

GIF animation screen captures from "Parallax/Solar System Modeler" http://www.astro.washington.edu/labs/parallax/solar.html (original link, defunct) http://www.uwlax.edu/faculty/sallmen/phy160/labs/lab3_files/uwash_files/solar.html (Astronomy Department, University of Washington)
