Some of the content types in the LabXchange library, such as Simulations and Pathways, include Questions related to the content. These questions are also available individually and as part of Questions Sets in the library, although please note that you will need to log in to LabXchange to view Questions Sets.
As a student, the questions provided on LabXchange will help you to get an idea of how well you understand the topics at hand. Any questions in the public library will allow you to select new answers until you get them right, and will generally provide some information or clarification when incorrect answers are selected. If the number of attempts has been limited, this will be noted next to the Submit button.
As an Educator, you can add existing questions to your own Pathways etc., or create your own. Strategically placed Question Sets can be helpful in highlighting important points in a lesson, or they can be used for grading by limiting the number of attempts and setting point allocations. This is often useful when creating content to be used in a Class.
