21st Century Content, 21st Century Learner, and 21st Century Etiquette?

While media literacy, environmental, social and global issues, finance, geography, civic literacy, civic engagement are all key contents for the 21st century, but how about etiquettes? Common courtesy?

Today's students are such passive learners, most of them. Perhaps they are overwhelmed with all the curriculum and tests and competitions and pressures. Perhaps they are used to have information pushed to them via digital media. Perhaps they were not taught by human about the proper etiquette and courtesy when it comes to using the digital media and resources.

Many of my students are so short on time and overwhelmed with curriculum/homework that they use technology mostly for socializing and not for learning or producing/making meanings. So how do we, as professional teachers, guide them towards Web2.0?
