2. First you need to know what a PLN is Personal learning network is connecting with others who share the same interest as you. Like looking at Twitter4Teachers. On this site there are over 40 categories of educators, each with a list of people, their location and their Twitter name. So I picked a few from each category, some close by, others in different parts of the world, added my name and almost instantly my Personal Learning Network began to grow.
