How to document the developed work using an agile methodology? In the final report of their internship, the students of our school must have one chapter where they "document" the developed work. When using the “waterfall” methodology, they usually have one sub-section for each stage: 


requirements
detailed design
implementation
tests
...


What if an agile methodology like XP or SCRUM is used? Every year we have the same problem, as some teachers say it should be done one way, while others say the exact opposite. 

Any ideas?
In SCRUM, during the end of each sprint, there is a Sprint Retrospective and Spring Review. Important artifacts from the two should be extracted into this report, as it reflects the "developed work".

I'm not sure the scope of what you require from your students for documenting the work, is it for the whole internship, or just one cycle? In any case, because Agile is done incrementally, they can just write one template per sprint they've completed.

Notes from sprint review
Notes from sprint retrospective
