I have recently been encouraged to engage with twitter in a professional capacity to better support my teaching.
The first thing I suggest you do is open a second account on twitter. To do so, follow the link instructions here.
Then from there you can sign in and follow the following links:
- The 60 Best Teachers to Follow on Twitter
- A colossal collection of Educational #Hashtags
- The Weekly Twitter Chat Schedule
- How to Search Twitter for Educational Content
They provide an excellent starting point for further exploration of education through the chatter available on twitter.
