<P ALIGN=CENTER><B>Number of Peer Assessors</B></P>
|
||
|
|
|
||
|
|
<P>A peer graded assignment will normally have around 3 to 8 peer
|
||
|
|
assessors. That is, in the peer grading phase, each student will be
|
||
|
|
asked to grade this number of pieces of work from the other students
|
||
|
|
in the class. The larger the assignment is, in terms of content, the
|
||
|
|
smaller this number should be, else the grading burden on the
|
||
|
|
students becomes onerous. However, each student should see sufficient
|
||
|
|
examples to gain an insight into what constitutes a good piece of work
|
||
|
|
and a poor piece of work. Further for the grading performance of a
|
||
|
|
student to be assessed meaningfully the greater the number of peer
|
||
|
|
gradings the better. This performance is unlikely to be valid if only three
|
||
|
|
or four gradings are done by each student.
|
||
|
|
|
||
|
|
<P>Provided there is enough pieces of work submitted (actually 10 or
|
||
|
|
more), the system will allocate each student at least one "good" and
|
||
|
|
at least one "poor" piece of work. However, this can only be done if the
|
||
|
|
teacher has graded the pieces of work BEORE the allocation of (peer) grading
|
||
|
|
work is done. The teacher does NOT, however, have to grade all the
|
||
|
|
pieces of work, a sample is sufficient. Further, the teacher's gradings need
|
||
|
|
NOT be the final gradings, a preliminary grading is good enough. Note,
|
||
|
|
however, that if the option to show teacher's gradings is turned on,
|
||
|
|
these gradings will be shown to the students at the end of the submission
|
||
|
|
phase.
|
||
|
|
|
||
|
|
<P>The number of peer assesors can be zero. In which case the assignment
|
||
|
|
becomes either a self-graded assignment if that option is turned on, or
|
||
|
|
a normal teacher-graded assignment.
