These days we write nearly exclusively on computers and smartphones, most often by email. For this reason, I request computers for course participants, as well as a computer with PowerPoint and a projector for myself. I also ask for a flipchart to show examples and highlight points not appearing in the PowerPoint or manual.
Having an internet connection in the facility also proves beneficial so that participants can email their writing assignment to me, and we can then project it to the entire class for review. I also browse helpful websites for writers during the course. Interestingly, those who might at first find such a critique of their work nerve-wracking later say how helpful the experience was.
