Helping Students Understand Grades

The concept of validity means the degree to which a measurement instrument accurately reflects whatever quality it is supposed to measure. [...]to be valid, your grading system must be tied to the course goals. An example is shown in table 2. [...]you can hand out a written description along with the assignment before the students begin. [...]descriptions provide a record for you, as well. To overcome these problems, you can impose a "time-out" for thinking by making it a policy not to discuss the grading of a specific piece of work until after some set time has elapsed. [...]many teachers will consider only grade challenges that are submitted in writing.
