The document discusses strategies for building an online learning community in large university classes. It recommends using social media and communication tools to increase interactions between professors and students and among students. This helps keep students engaged with the class material before, during and after class sessions. The document argues that a connected community of learners can enhance the learning experience over individual learning by answering each other's questions, providing peer support, and allowing knowledge and projects to develop collaboratively. It provides examples of how online communities have helped facilitate events like a Skype session with a Nobel Prize winner. Overall, the strategies aim to create an extended network of lifelong learners that continues beyond a single class.
