How could I plan a peice of persuasive writing?

In English Language exams you may be asked to write persuasively in favour of some viewpoint (e.g. 'Britain should continue to have a royal family') 

MATERIAL

Firstly, you may like to begin planning your answer with a rough list of arguments for the viewpoint and possible arguments against. Whilst gathering your material you should think about:

1) Which of the arguments in favour of the viewpoint are the strongest, clearest and most simple to make? Often these will be the first arguments you think of in response to the statement. It much better to communicate a simple argument well than try to express more complex points in an unclear way! Don't make things harder than they need to be!

2) Which of the arguments against the viewpoint can you think of a response to? Although we are not writing to argue (and so don't need to include opposing opinions) including these arguments in your essay, and then effectively opposing them with a response will make your writing extremely persuasive. 

STRUCTURE

After you have gathered all of your material, it is time to order it into a structure. You might find that different peices of writing work best with different structures. Here are a couple to consider:

Structure 1: [Introduction] [Strongest pro argument] [Next strongest pro arguments] [Strongest against argument and your reply] [Next strongest against arguments and your replies] [Conclusion]

Structure 2: [Introduction] [Strongest pro argument] [Strongest against argument and your reply] [Next strongest pro argument and your reply] [Next strongest against argument and your reply] [Conclusion]

INTRODUCTION AND CONCLUSION

Now that you have your material and your structure, you can begin writing! 

Your Introduction: Should very briefly outline the viewpiont and why you think it is true. Hint at some of the points you are going to make to back it up. 

Your conclusion: Should summarise the points you have made and re-iterate your viewpoint!
