A SCO consists of instructional content on chemistry lab safety and questions to check the learners' understanding. Under a normal mode, the SCO is built to present all of the instructional content and assessment questions. Both the instructional content and assessment questions should be presented to the learners for completion. The SCO is also built to communicate the learners' progress to the learning management system (LMS).
This is only an example of how Mode could be used by a SCO.
