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.

the topic

Collect much information; but very limited relate

to the topic

Collects some basic information; most refer to

the topic

Collects a great deal of information; all refer to

the topic

Ex: 4

Fulfill team’s roles & duties

Does not perform any duties assigned to the team role

Performs very little duties but unreliable.

 

Performs very little duties

Performs nearly all duties

Performs all duties of assigned team roles

Shares work equally

 

Always relies on others to do the work

Rarely does the assigned work; often needs reminding

Usually does the assigned work; rarely needs reminding

 

Normally does the assigned work

Always does the assigned work without having to be reminded.

 

 

3

 

Listen to other Team mates

 

Is always talking; never allows anyone else to speak

Usually does most of the talking; rarely allows others to speak

Talks good; but never show interest in listening others

 

Listens, but sometimes talk too much

 

Listens and speaks a fair amount
