Pools are collections and groups of questions that you can include in tests and surveys. For example, you might have a set of 10 or 20 related questions you want to reuse in several tests or surveys, or even across multiple courses. The advantage of using a pool is you do not have to remember all those questions and manually add them to each test or survey.
The Pool Canvas for a question pool presents an inventory of all the questions that you can manage and search. You can edit the pool names and instructions, create or edit questions, and upload questions. Use the check boxes to select individual questions or all questions, and then delete them or change the point values.
When you select pool questions for a test, links are created between the test and the pool questions. Changes to linked questions produce a warning message that the changes take effect everywhere the question appears.
A warning appears if you edit a question where students are in the process of taking a test or have already taken a test that includes questions from that pool. Certain areas of the questions will not be available for modification if the test has already been taken by students.
After students start taking a test, you should not make changes to pool questions deployed in the test. If you edit a pool question after a student has submitted a test it was included in, the student will view the new modified question when they view their grade and feedback. They will not view the original question.
When you create pool questions that are intended for use in surveys (which are not graded), correct answers must be added during question creation. This enables the questions to be used in tests as well as surveys. These answers will be ignored after the question is added to a survey.
Linked questions are indicated by a globe icon. Changes to linked questions produce a warning message that the changes take effect everywhere the question appears.
If the question has attempts, changing it will require any submitted attempts to be regraded and may affect test scores. If this happens, affected instructors and students are notified.
