methodology:
Introduction:
( the intro of your research .. dont write everything just 4 or 5 lines )
Chapter One : ( here write the title of this chapter)
( then write two lines just to show what it will be covered )
Chapter Two : ( you may have one or two or three chapters .. its up to you but its also depends on your ideas ^^ )
Conclusion:
5 lines are enough
...
A proposal is just a plan for your research
=)
good luck
