Gabriel Marquez outlines the key components of their personal learning network (PLN). The PLN utilizes social networks like Facebook and Twitter to stay connected with peers and professionals, informative websites to increase knowledge on topics related to teaching, and sites that allow sharing of information like tutorials, papers, and presentations. E-mail is also used to exchange documents and information that require review before being shared more publicly. Overall, the PLN is unique and personalized for the individual to enhance their professional development and growth through curating and expanding the resources in their network.
