Letting Students Resubmit Work

After viewing the Redos, Do-Overs.... video (see Web Links) I changed my mind about students submitting work after a due date. I often give zeros or a severely reduced mark for late work. I would still do this but the change I would like to make is to develop a policy of 'If the student is not happy with their result they can redo the task' and receive a new result counting towards their final grade. There would need to be guidelines around this and advertised to the class so they were aware they could redo learning tasks. If a student wants to put the effort in to improve their learning while keeping up with their other work I would be all for this. I'm not sure how many students would take this up but those that do will have improved their learning and get a real sense of achievement from redoing a task.
