SUGGESTED LIST OF EXERCISES/PRACTICAL
The practical/exercises should be properly designed and implemented with an attempt to
develop different types of skills (outcomes in psychomotor and affective domain) so that
students are able to acquire the competencies/course outcomes. Following is the list of
practical exercises for guidance.
Note: outcomes in psychomotor domain are listed here as practical/exercises. However, if
these practical/exercises are completed appropriately, they would also lead to
development of certain outcomes in affective domain which would in turn lead to
development of Course Outcomes related to affective domain. Thus over all development of
Programme Outcomes (as given in a common list at the beginning of curriculum document
for this programme) would be assured.
Faculty members should refer to that common list and should ensure that students also
acquire outcomes in affective domain which are required for overall achievement of
Programme Outcomes/Course Outcomes.
