After writing my Teacher Challenge guest post on using Twitter to build your PLN, I was asked by a number of people about hashtags.
I know when I first started using Twitter, it took me a little while to get my head around what the # symbol meant. This is a handy feature of Twitter that is worth learning about.
What is a hashtag?
The # symbol + a word/acronym in a tweet is called a hashtag. It is used to categorise a tweet into a topic or keyword. Hashtags are not created by Twitter but by Twitter users.

Why use hashtags?
There are so many tweets flying around at any one time that they can get lost in the crowd.
If you click on a hashtagged word in any tweet, you can find a list of other tweets with that hashtag. Whether or not you’re friends with someone, you can find their hashtagged tweet (as long as their profile is public). If you add a hashtag to a tweet, your tweet can potentially reach a larger audience.
Hashtags can help you connect with people who have similar interests. For example, you might be doing the Daily 5 literacy program in your classroom but you might not know any other people on Twitter who are also using that program. You could go to the Twitter website and put #daily5 into the search box to find a list of tweets from people tweeting about this subject.

If you use a desktop application like TweetDeck, you can add a column with all the tweets on #daily5 so you don’t miss anything.
In TweetDeck just click on the + sign at the top of your screen and then put #daily5 (or your favourite hashtag) into the search box. Alternatively, you can click on a hashtag in any tweet in TweetDeck and a column with all the tweets with that hashtag will be added.
Hashtag etiquette
Most Twitter guides suggest one, two or three hashtags is a good amount to use. Any more than three hashtags can take away from the content of your tweet.
Where do you put hashtags?
Hashtags can replace a word in a tweet or be tacked on to the end of a tweet. Sometimes people put a hashtag at the start of their tweet to preface their message with the subject.

Who makes up hashtags?
Hashtags are community driven. You can create any hashtag you like as long as members of your community or professional learning network (PLN) know about it and agree to use that hashtag.
To avoid using a hashtag that is already being used, it is advisable to search for that hashtag first. Things can get confusing if your hashtag is being used by another group! http://hashtags.org/ is a useful website to find out about hashtags being used.
The lighter side of hashtags
More and more people seem to use one-off random hashtags to add a humourous element to their tweet. You definitely don’t want to overdo this but they can add a little fun to your interactions with others.

Conference backchannelling
Most conferences these days have a hashtag. This will generally be advertised prior to the event and allows people to connect their tweets about the conference before, during and after the event.
A hashtag can be used for a conference backchannel. Backchannelling allows conference participants to engage in an online discussion about what they are seeing, hearing and learning. It allows passive audience members to become active. Sometimes, people who can’t make a conference will also get involved in a backchannel by following the hashtag.
If you’re on Twitter you might have seen many tweets flying around with the #ISTE11 hashtag recently. This hashtag allowed participants at the ISTE conference in Philadelphia to connect while also giving a running commentary to non-participants.
Tweet chats
Usually, conversations on Twitter are interspersed with gaps of time while people come online and offline. Some people plan times when everyone is online to engage in a live chat about a certain topic. These are often called “tweet chats” and are defined with a hashtag.
One of the most well known tweet chats in the ed tech world is #edchat. Each week there is a different topic and up to 2000 people from around the world get together and have a focussed conversation.
You can use a client like TweetChat to converse in real time or you can simply add a column with the hashtag search to TweetDeck or whatever Twitter application you prefer.
Anyone can organise their own live tweet chat. Just come up with a hashtag, a time and a topic, and get your PLN on board!
Archiving conversations
If you want to keep an archive of hashtagged conversations from a conference or tweet chats, there are some websites that make it easy to do this. Try Keepstream or Twapper Keeper.
Trending topics
You may be aware that Twitter is often the first place to break news as it happens. Twitter has an algorithm to work out which topics or hashtags are the hottest topics or trends right now.
If you go to the Twitter homepage, you can see a list of trending topics or trends. There might be hashtags there that you want to follow! These aren’t all hashtags but if you click on any of the trends, it will take you to search results of tweets about the topic.
These trends can change by the minute.

15 Blogging Tips for Students and Teachers
This post was originally published last year as 10 Blogging Tips for Students and Teachers.
As I regularly help students and other teachers set up their blogs, I find myself giving lots of little tips that I have picked up on my own blogging journey.
My list of tips keeps expanding and I thought it was timely to republish an updated version of this post.
Many of these ideas have originally come from some of my blogging “mentors” such as Linda Yollis and Sue Waters.
Here are 10 15 Blogging Tips for Students and Teachers
1. Post frequency: Find a balance. Don’t post too often (ie. daily) otherwise you will not be able to generate much conversation through commenting and readers won’t be able to keep up. Post too infrequently (ie. monthly) and your readers might start to forget about you.
I advise my students to post no more than once or twice a week, while three times a week works well for my class blog. Decide what works for you.
2. Reply to comments: I am often disappointed by student and adult bloggers who do not reply to their comments on their own blog. I feel that it is basic blogging etiquette to reply. Acknowledge your readers’ comments, interact with them and they will be encouraged to comment again.
3. Have an “About” page: The first thing I do when I visit a new blog is look at the About page. I am always disappointed when there isn’t one! Don’t keep your readers in the dark about who you are and what you’re blogging about.
4. Theme changes: Students love playing around with different themes when they first start blogging. I encourage them to explore for a week or so but then advice them to find a good theme and stick with it. Readers may be able to identify less with your blog if it looks different every time they visit it.
5. Fun widgets: Young bloggers love widgets! In my opinion, it is advisable to limit “fun” or “novelty” widgets. Too many widgets take away from the actual content of the blog posts and can slow down loading time! I suggest my students have no more than three “fun widgets” such as virtual pets, Christmas countdowns, jokes, tips, music clips etc.
6. Add a search box: Early on in the year, I teach my students how to use the search box on blogs to find content. I find it frustrating when blogs don’t have the search box. This simple tool allows readers to find what they’re looking for and means when your posts are no longer on the front page, they won’t be lost.
7. Subscribe via email: While I also use Google Reader and Twitter to keep track of blogs I like, I love having the ability to subscribe via email to my favourite blogs. Adding this feature could bring more regular visitors to your blog.
8. Add links to blog posts and comments: Links help your visitors gain a deeper understanding of what they’re reading. Links in blog posts can also be used to acknowledge or compliment others’ work. Links in blog comments can add extra information to a conversation. If you don’t know how to add a link to a blog comment, check out Linda Yollis’ excellent blog post and quick video.
9. Visit other blogs: You can’t expect many people to read and comment on your blog if you don’t read and comment on others’ blogs. You have to be part of the blogging community to get the most out of blogging.
10. End with a question: On my class blog and this blog I like to end with a question to stimulate and direct conversation in the comment section. My Grade Two bloggers are learning how to ask “broader” questions that will appeal to more readers (eg. if a child writes a post about a holiday to Noosa, instead of simply asking “have you ever been to Noosa?” they could ask readers to leave a comment and describe a holiday they have been on etc).
11. Don’t lose your comment: All my students now know how to select all (Control A) and copy (Control C) their comment before they hit “submit”. This allows them to paste (Control V) the comment if something goes wrong when they hit the “submit” button. This happens fairly frequently with young students due to the wrong spam word being entered etc. Read My grade two student Millie’s post about this tip here.
12. Left align your writing: I used to be guilty of centering all of my text until I realised this is not easy on the eye and not what professional writers do (always good to look to the professionals for guidance when in doubt). Style guides usually suggest that centered text is best for invitations, posters, headings etc.
13. Use paragraphs and sub-headings: As a writer, you need to do as much as you can to make your post easy to read. I am likely to stop reading something that doesn’t have any paragraph breaks. The more your writing is spaced out the better. Having key words or sub heading in bold/colour can also make your post easier on the eye.
14. Don’t copy and paste from MS Word: If you’ve been blogging for a while you may have experienced the dreaded consequence of copying and pasting text from Microsoft Word into a blog post. It is a big no no! Doing this can give you bad code which can ruin the layout of your blog.
If you do want to copy and paste from Word you either need to paste the text into the HTML section of your editor or paste the text into Notepad (or the Mac equivalent) and then copy and paste that text into your post editor. If you want to read more about this, check out Sue Waters’ post here.
15. Stick with it: One of the biggest mistakes bloggers make is to give up too easily. Stick with it and reap the rewards!
