As a start, there is:
- writing something in a shared space
- reading something someone else wrote
- replying to something
- rating something (selecting a score from a list of options to express your opinion of value)
- building and maintaining a network (and all that goes with it - i.e. needs unpacking),
- sharing a link via social bookmarking
Of course, implicit in this some of the items in this list is an ethic that values sharing and an in-built commitment to and awareness of the network(s) in chosing what move to make while engaging in learning activity. If we are to see students becoming networked learners, they will not only have to perform the items in the list with sufficient elan, they will also have to become 'network aware'. Is this too much to hope for? Or is it possible to so design curricula and constituent activities that require networked learning activity for long enough for students to become wired to 'think the network'?
