Much has been written about this subject. I do suggest you go over Steve Wheeler’s Blog… it’s one of the best blogs discussing Education, I have come across. Do have a good look at it and check out what Professor Wheeler blogs about… his blog archives are one for the most extensive in Educational Technology.
So basically some of the reasons are highlighted in Steve Wheeler’s blog, but I think that the most important thing is the “glue” which blogs can provide to the outside world. Blogs give you a voice, and that voice is easily published across the really Wide Web in one click. Your voice can be heard and you can hear other people’s voice. It’s not just you and your colleagues in your immediate staffroom… when you go in to the staffroom and you share something with your colleagues, whether it’s a joke or a complaint, or a thought or something which you have done and which you are excited about… you simply share it with a maximum number of maybe 10-20 people…but when you blog about it… suddenly you share it with so many more people. Blogs are a way to help you build your network, and blogs like everything else, will not reap the fruit of your efforts overnight. You need to nurture them with your thoughts constantly. It’s like writing a diary, and once you start then it becomes a part of who you are.
Therefore Blogging for Educators, is for me, a very important form of expression because it removes that sense of isolation which is sometimes built around the perception of a teacher (you know… the teacher is alone in his/her domain in the classroom) and paints a whole new image of the teacher, with multidimension, as the teacher or Educator’s experience grows and evolves with each passing day.
If you still haven’t started off blogging, you will find many tools which can help you. My personal suggestion is to use either Blogger (which uses your google account) or else WordPress (such as this blog you are using). Both are free for you to use.
