Level
3- Highly Addressed, Level 2-Moderately Addressed, Level 1-Low Addressed. Method
is to relate
the level of PO with
the number of hours devoted to the COs
which address the
given PO. If >40% of
classroom sessions addressing a particular PO,
it is considered that PO is
addressed at Level
3 If
25 to 40%
of classroom sessions addressing a particular PO, it is
considered that PO
is addressed at
Level 2 If 5 to 25%
of classroom sessions addressing a particular PO, it is
considered that PO
is addressed at
Level 1 If < 5% of
classroom sessions addressing a particular PO, it is considered that PO is
considered not-addressed. |
