I have never heard of Personal Learning Networks before; but, upon my research I found out how easy they are to learn as well as how helpful they are. Personal learning networks are a quality list of set people and tools that you can call upon for help. It is those people, places, organizations, and activities which will enable you to learn. Watching the YouTube video Welcome to My PLE! was really cool and helped me to understand more about PLN's. PLN's are great because they are worldwide and are usually free. If not free most PLN are very cheap. PLN's are all over, you may be using one and not even realize it. Twitter, Facebook, and even YouTube are all considered PLN's. PLN's can help you with teaching, you can connect with others and see how they are teaching the lesson, or even watch videos on how they teach their lesson.
