There are many great teachers who use Twitter to communicate questions, answers, and resources with other like-minded teachers. No teacher is an island with an effective Twitter stream. If you wisely choose those who you wish to follow, you can learn much from experience teachers who have already traveled down the road you may be starting.
My biggest tip is to find an educational leader that you respect and see who they follow. One can mostly avoid blind searching for professional leadership if you know that those you respect may have already vetted the authenticity or usefulness of those that they follow. Unfortunately, it also opens you up to certain education leaders who spend 80% of their time tweeting about where they ate BBQ or their latest golf score and 20% of their tweets are actually useful.
A recent article was published by Education Next giving a list of the top 25 Education Tweeters and policy makers. I was glad to know that I was already following a number of them, but found some new ones I may soon add. If you are wanting to pad your PLN, check out some of these names. (Good bets: Wesley Fryer, Steve Dembo, Ewan McIntosh, and Vicki Davis just as starters.)
There are a number of 'How To Twitter in Education' blogs out there, so I won't attempt to recreate the wheel. However, to make Twitter really work for you, keep a couple of things in mind. If you respond to and retweet the tweets that you find valuable, the originator will be more likely to start a dialog with you. Just lurking (reading only with no actual tweeting) will get you some good information, but getting answers from your posted question benefits from having people who recognize your Twitter name.
Also keep in mind that the many mobile Twitter apps out there are great for keeping your finger on the pulse of your feed and often aid in Twitterburn, that reaction to over-usage that Alka Seltzer can't fix. My Alka Seltzer for Twitterburn is a free iPad app called Flipboard. It puts your Twitter stream all together in a visually pleasing and easy to browse view. It's worth ten times what I paid for it. ;)
Happy Tweeting! Feel free to share your Twitter resources below! Maybe we'll bump into each other out there. @mrmartinsclass .
