The presentation will show the types of online writing tasks that can be integrated in online courses, online discussion forums, blogs, wikis…etc as a supplement to in-class writing instruction. The types of online writing tasks include the following: Tasks that focus on specific writing skills; tasks that provide free writing activities; tasks that provide extension activities; tasks that require students' comments; pre and post-writing instruction assessment tasks; error correction tasks; remedial tasks; self-improvement and study skills tasks; electronic searching tasks; tasks that require reflective thinking and others. Online writing tasks can be performed individually, in pairs or in small groups. They can be performed synchronously or asynchronously; independently, interactively or collaboratively. Examples will be given to illustrate the task types and task phases, i.e. pre-task phase, task cycle, post-task phase, and assessment.
