I have an assessment task in which we have to do a 10 minute presentation on the social exclusion of a group in society.
Just adding to what's above.
1. Intro - exactly as k.herc said you could define social exclusion and all that and perhaps also introduce a key group or 2 you're going to focus on as a case study.
As the presentation goes for 10 minutes you could structure your paragraphs as so
2. What factors cause exclusions of groups. Perhaps give a general overview and then pinpoint it to your particular group. This could focus on how varying beliefs etc lead to exclusion and then give a history behind why your particular focus group/s faces exclusion.
3. How is social exclusion evident in society today. Go into the way it is seen and again bring into play your social group.
4. Discuss how social exclusion affects individuals and/or discuss how the group has been affected i.e. has social exclusion solidified them as a group/community or disbanded them.
5. Conclusion: bring this all together.
I didn't society and culture so I apologise if this is completely on the wrong track but I hope this helps a bit. Good luck
