Found through the S.O.S. for Information Literacy database, the Cornell University Library offers one web example of an evaluation for a one-shot workshop session. It has ten questions that include scale multiple-choice questions and short answer comment boxes. The S.O.S. database recommends providing this to participants at the end of the session.
What’s effective about this questionnaire is that it first assures the user that it will only take 4-5 minutes to complete. Questions follow similar formats (a range between strongly agree and strongly disagree). On the librarian side, web surveys are efficient in that data is aggregated in one place and can be viewed in multiple formats and shared with multiple library administrators easily. Google Forms is another good tool to create feedback forms.
Since feedback is anonymous, users can provide honest criticism and praise for the usefulness and relevance of the session.
