There are dozens and dozens of free online genealogy classes now available at FamilySearch.org - covering topics ranging from beginning genealogy research in several different countries, to reading handwritten records (multiple languages to choose from) and research principles and tools. These new classes are self-paced and entirely free to everyone. Most include a video lesson. Some also include a course outline or handout. There's also the opportunity to provide feedback on each class.
If you're a beginning researcher there are plenty of basic options here to get you started, from "Beginning" courses in U.S., German, Russian, Italian and Polish genealogy, to overviews on sites such as GenealogyBank.com. There's even a great course sponsored by the Midwest Genealogy Center titled "Tips and Tactics from 50 Years of Research."
There are many options for those of us who have been doing this for a while as well - from the wonderful "Inferential Genealogy" class from Thomas W. Jones, PhD, CG, CGL, FASG, FUGA, FNGS to "Polish Displaced Persons" by Ceil Wendt Jensen MA, CG. I'm also looking forward to delving into some of the great classes in the "Reading Handwritten Records Series."
