A personal learning network is a collection of people one engages with online to exchange information, usually for professional development purposes. As a teacher, personal learning networks can be used to locate classroom resources, get lesson plan ideas, learn about new technologies, and find solutions through collaboration. Various online tools that can enable personal learning networks include blogs, Nings, TED Talks, microblogging, and social bookmarking. These technologies allow access to experts, specialists, and communities for teachers to continue developing their knowledge and skills.
