TASK: How to create an enviroment where students want to write...

I am not a good writer - so before I start teaching how to write, I have to improve my very own writing skills.
This is the first step a teacher could take to create an enviroment where students want to write. Teachers are role-models, so how can we expect students to write when the teacher does not seem to enjoy writing himself?
In my opinion another factor is to give students positive feedback. Of course the teachers should help the students to get better writing skills. Instead of telling the students what they did wrong I prefer to give feedback about the things they did well. Additionally the students have to get tips about how to improve this productive skill.
A third point that comes into my mind when I think about a good writing enviroment is "learning by doing". Students need practice to get a feeling for writing texts. So I am of the opinion that we should offer to write something whenever it is possible - even in maths lessons! Student could also reflect their own learning progress in a learning log or write about hobbies or family activities.
This brings me to a forth point: Students should have to change to write about topics they are intested in, in a way they like to write. For me it is much easier to communicate about topics that I am familiar with. The others in the peer mentor group agreed with me. So I thing we should give students the possibility to express their thoughts about things they like to talk about. The focus should be on expressing what they want to express instead of sticking to a genre or specific type of text.
Of course, there are more factors which help to create an enviroment where students want to write. If we combine the four suggestions I just mentioned a first step into the right direction is done. Now I am exited to read about the ideas the others had...
