Lots of it! Writing independently, assessing, and giving them targets for the next piece of writing. I tend to get them to write 20 minutes of independent writing in each english lesson.Some only write a couple of sentences the first time they do it, but they get the idea after a while with constant assessment and targets.I also get them to write the date and the learning objective before I start teaching, so that when they start the independent writing, they can just write. Another idea I tried was to get them to write 5 sentences about a given subject before I started the lesson. It could be something like 'What did you do last night?' I would sometimes limit them with something like: You must write 2 simple sentences, 2 compound and one complex. Other times, I would just let them write. I would always give them a target when I marked this writing.
