How to Write the Introduction for an Assignment? Some would say introduction is a guidebook, some would characterize it as the context list of a magazine and some would define it as a map of the assignment. Whatever you call it, the function of the introduction remains the same. It must reflect the purpose of writing the assignment, consist of the important terms and signify the findings of the assignment. It requires too many criteria to make it perfect. This is why students start to feel annoyed while composing an assignment introduction. You may have countered the same situation, gaping at a computer screen and nothing worth coming out of your mind.
