HowTos for teaching and learning
All the Debian packages on this page can be installed by running either aptitude install <package> or apt-get install <package> (as root).
Moodle is a free, Open Source course management system - software designed using sound pedagogical principles to help educators create effective online learning communities. You can download and use it on any computer you have handy (including webhosts), yet it can scale from a single-teacher site to a University with 200,000 students. Some schools in France use Moodle to keep track of students' facilities and credit points.
There are moodle sites all over the world, mostly concentrated in Europe and North America. Check the site of an institution near you to get an idea about it. More information is available at the moodle project page, including documentation and support.
SWI-Prolog is an open source implementation of the programming language Prolog, commonly used for teaching and semantic web applications.
Warning: make sure you know the status of the laws about monitoring and restricting computer users' activities in your jurisdiction.

HowTos from wiki.debian.org
The HowTos from http://wiki.debian.org/DebianEdu/HowTo/ are either user- or developer-specific. Let's move the user-specific HowTos over here (and delete them over there)! (But first ask the authors if they are happy with moving them and putting them under the GPL - see the page histories to find them.)
