tor The Educator's Guide to Hashtags By careertechtesting.blogspot.com Published On :: Wed, 13 Jan 2016 18:26:00 +0000 Follow us on Twitter! @CareerTechTest Whether you're a social media novice or not, hashtags may seem confusing and inessential. These short links (hashtags) preceded by the pound sign (#) are integral to the way we communicate online and it's important to know how to use them. Can hashtags be fun? Absolutely! On Twitter, the pound sign (or hash) turns any word or group of words into a searchable link. This allows you to organize content and track discussion topics based on those keywords. So, if you want to post about the NFL Super Bowl, you would include #SuperBowl in your tweet to join the conversation (or simply search for the hashtag to follow the discussion). Clicking on a hashtag will allow you to see all the posts that mention the subject in real time. I also recommend using a social media management platform, such as HooteSuite, TweetDeck, etc., where you can create columns with hashtag topics. I like the ability to monitor several discussions, i.e. #edchat, #lrnchat, #careerteched, at once and all on the same screen. I've created a list of popular educational hashtags and tried to categorize them for you (see below). It definitely isn't all inclusive, but it's a good starting point and I hope you will share any new educational hashtags you find interesting and helpful! (Also, hashtags are now a staple to social media and their use has been extended to other social media platforms.)
