I read a recently published review, Pedagogical Cultures in Transition (in Finnish), by Kari A. Hintikka, who holds that in education, social media is used as enabler, facilitator, or reformer. It can either just replace old tools or it can reform pedagogy. The key contribution of social media in education seems to be that it facilitates participation and co-operation. As an example, the review used a joint assignment divided into smaller pieces —microtasks. An individual can freely choose his role and the ways he participates in the project: he can generate ideas, gather information, write, comment, proofread, or simple vote for the solutions adopted. This sort of freeform collaboration combines knowledge in a new way, and the threshold for participation is low. Even a small contribution, however, will increase interest and commitment to the task. And thanks to social media, you can take part at any time, from anywhere, without needing any special IT skills.
