Instructors may configure Labster simulations through Sakai Assignments or Sakai Lessons (adding Labster via Lessons is highly recommended). Follow these instructions to access a Labster simulation through Lessons.
Select Lessons.

In the target Sakai site, select Lessons.
Note: The course instructor may have renamed the Lessons tool, or there may be multiple Lessons tools in the course.
Select a simulation.

Select the title of the Labster simulation.
Simulation loads.
The Labster simulation will open in a new browser tab. Allow the simulation several minutes to load, and do not navigate away from the tab while the simulation loads.
Select Start.
