Question

Offer constructive suggestions for own role in supporting planned learning activities

Answer 1

In constructive criticism, we provide valid and well-reasoned opinions in order to improve the outcome of the event/activity, not tear one's spirit apart. 

For example, lets say i'm a leader of a study group.

My own constructive criticism would be :
As a leader, i should have paid more attention to the member's progress in the study group. I could've done it by checking their understanding from the topics that have been discussed during the session.

Answer 2

If you would like to offer a constructive suggestion for your own role in supporting a planned and or learned activity, you would essentially be trying to give something constructive back to your group in which you've worked.
An example would be, if you're in a newly formed group and you want for the group to work optimally. YOu would provide th egroup leader with info on how he could improve in the future.
