What are the mean and standard deviation to curve grades that you customarily use for the peer-evaluated writing assignments?
For the mean, I would pick the mean final class grade the last time you gave this class, unless you have some belief about why the writing grades should be higher or lower than the grades generated from the other activities. That way you are not radically changing the grades associated with the course as a result of using SWoRD. For the standard deviation, I usually pick 10%, which means that about two thirds of the students’ SWoRD grades will be roughly the mean letter grades (a B and C in my classes).
