We live in a great time for self-directed, on-line CS education; students should find programs they like and become a part of those communities.
(If the links below don’t work for you, do a Google search on the program name.)
If you’re interested in developing mobile apps, take a look at Android AppInventor at http://appinventor.mit.edu/ ;
if you want to make some simple games and animations, take a look at Scratch at http://scratch.mit.edu/ ;
and for a good starting point, visit http://www.code.org/ .
If you don’t have access to a good computer and internet connection at home or with a relative, check out your local library or other community resources. Many of these courses and programs don’t require software installation.
