Tutorials: for those with no experience with variable stars and very little astronomical experience. They walk you through the basics of variable star science and provide challenges to apply the concepts.

Why observe variable stars (and yes, you can do it too!) AAVSO board member Bill Stein and the Astronomical League presents why variable star observing is such an important facet of astronomy. Stein also touches base on how observing with the AAVSO communicates important data to professional astronomers. Starting at 22:29 in the video,
