I have quickly become a twitter-a-holic checking the stream several times a day, finding articles of interest, adding them to pocket or flipboard and referring to them for my blog posts, my staff trainings as well as my personal training. I have learned so much from the PLN and others who are out there joining in the chats. The professional development I have gained exceeds what I have paid for. I attend a lot of conferences and PD. Our school has a weekly PD where we cover various topics necessary for our classrooms. While it is a good way to learn from our co-workers, I think learning from others in other places is also a great help. It shows us we are not alone. I am the only French teacher in my school. Often, I don't have someone with whom I can collaborate and share ideas. My French PLN is like PD everyday. I am also the only librarian in my school and while I have a lot of local librarian colleagues, chatting via twitter with others is a great learning experience. I have met so many wonderful people dealing with similar situations as me.
Twitter as a PD is a tool everyone in education should try. I recommended to some of my colleagues to join twitter just to learn from others. I told them they don't have to tweet, they can just follow. A few have started and have reported back the cool things they are learning. I have managed to learn about content, commom core, web 2.0 tools, authors, books, library science, my library software, screencasting, flipping a class, just to name a few. It doesn't take much time. Just a few minutes a day can provide anyone with a plethora of information that can benefit the educational environment.
I LOVE twitter and if we could convince every educator, administrator and school board member to take a peek, I think our educational world would be a very different place.
