P/S my apologies for the late post.
For learning to occur there has to be a question to think about and content to interact with, and by content I mean credible online sources with which one can reference one’s thoughts or argument to build upon or challenge.
In Web 1.0, content created became very accessible. Then came Web 2.0 technology which allows for people to interact with contents shared; Brown and Adler described it as “a new kind of participatory medium that is ideal for supporting multiple modes of learning.” The affordances of Web 2.0 has made a great impact on social learning, which Brown and Adler described as “understanding of content [that] is socially constructed through conversations about that content and through grounded interactions, especially with others, around problems or actions.”
Prior to Web 2.0 there were some social learning in / outside traditional classrooms but with Web 2.0 more people can now interact in or contribute to a conversation. Web 2.0 has made possible for the community of learners to have access to more ideas and learning from peers whom you don’t normally hang on with. For example, in a online course I took in Fa’12 where three generations of pedagogy was discussed, I could not understand what connectivism is even after reading the article. For one thing I have never heard of it like I have the social-behavorial and socio-cognitive approach. The instructor gave his take on it but the concept/pracitce was still unclear to me until one student described and explained his reading and understanding of connectivism from another book. That was when I first felt the power of sharing in social learning. This affected me as an instructional designer as I embark on a project to develop an open course in iTunes U. I would push for an open platform to allow the community of learners to discuss and share their thoughts in the learning journey.
