my wife is a teacher, and a common complaint by her and her colleagues is that teaching materials are virtually impossible to find online. there are sites which offer lesson plans and example work, however these are either lacking in content or paid-subscription. edubuntu provides an opportunity for addressing this issue - by providing a set of opensource tools for lesson planning, scheduling, grading, and classroom use edubuntu is has an opportunity to establish (or contribute to) a shared database of teaching resources. if teachers could elect to participate in such a database, edubuntu could transparently (or on a per-document basis) submit all lesson plans, class schedules, tests, activities, etc to a publicly available and searchable database. i'm not particularly familiar with the software included in edubuntu, but if there were a way of tagging documents with the relevant subject matter, age/grade level, topic, class name, etc - it would not take very long before a massive database of teaching materials was created. i'm thinking of something along the lines of wikipedia for teaching materials. it would allow teachers to spend less time re-inventing the wheel and more time building upon the work of others or investigating alternate approaches to teaching. many subjects are essentially standardized - it's an incredible waste of human resources for each teacher everywhere in the world to design a curriculum to teach the same thing - especially when the curricula produced are often almost identical. i don't know if this is something edubuntu would be interested in supporting - i had the idea talking to my wife a few days ago and thought i'd pass it along in case you guys were interested.
