Scenario Based Instruction

I am thinking about the importance of including scenario-based instruction in eLearning content. 

I read on the CITT site, they suggest using "scenario-based practice every 3-6 screens." 

Scenario-based instructions gives the student the change to apply the information in a meaningful way. For example, the content is about medical procedures to employ based on a patient's condition. A scenario can be presented to the learner about a patient with particular symptoms. The learner can choose the best option in which to employ, then based off their selection, feedback is provided. 

Scenario-based instructions are excellent options to provide learner-centered, active and authentic content. A main challenge is of course, coming up with the scenario and utilizing the right kind of authoring tools to develop the scenario.
