Thanks for your words of support. Putting distance between it and my feelings now is making me feel less angry about it. There are many teachers online who use their own names to further the field of pedagogy. Those who back up open work on developing teaching practice with information on the Internet. This type of forum is a different matter. But why should we be afraid to put our names to our beliefs of how best to teach our students. This has made up my mind to carry on tweeting. And while you might say protect your tweets, it defeats the object of reaching out to other teachers and you also won't be able to take part in discussions. I will smile sweetly and tell them I am only prepared to discuss progress at parents' evenings.
