The Comprehensive Dictionary of Educational Hashtags for Teachers at http://www.educatorstechnology.com/2013/09/the-comprehensive-dictionary-of.html
Most of my Twitter interaction includes hashtags. I use a wide variety of hashtags to follow and participate in discussions around a particular topic. I do have some specific hashtags that I use on every day basis such as #edtech, #education, #phdchat, #ipadded and a couple more but sometimes my selection goes way beyond that to include other hashtags depending on the type of search I am doing.

I personally view hashtags as the key to any professional development using Twitter and now that my Twitter use depends almost wholly on them I just can't imagine capitalizing on the educational potential of Twitter without the effective use of these symbols. In several instances, Educational Technology and Mobile Learning has posted lists of educational hashtags but none of these lists has been as comprehensive as the one below. Teachthought has made a great job in compiling this wide selection of education hashtags from different sources. I invite you to have a look and select the ones that relate the most to you.
