Context Scenario

I have began studying Interaction Design in University this year. We have been asked to answer the following questions:

Discuss how context scenarios are developed, & their use in the design process.

I've tried googling this, but the only results I found were regarding "Scenarios" in general.

I couldn't find anything in great detail specific to Context Scenarios

For example, one article gave a general overview of "Scenarios", and mentioned briefly different types such as Context, Keypath, etc. but again, nothing in great detail.

Can you guys please help me out, and perhaps point me to some useful resources that could help me answer the above question?

Thanks a lot for any help.
