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. |
