The introduction is the broad beginning of the paper that answers three important questions:
Rationale - this comprises an overview of the background knowledge in the field (and was expanded on in the Literature Review that was written after the Introduction). Make sure all variables are explained in detail here (dependent, independent and controlled).
You should provide a thesis early in your essay -- in the introduction, or in longer essays in the second paragraph -- in order to establish your position and give your reader a sense of direction.
Section I - Thesis Introduction
It is true that the first impression—whether it’s a first meeting with a person or the first sentence of a paper—sets the stage for a lasting impression. The introductory paragraph of any paper, long or short, should start with a sentence that peaks the interest of readers. In a typical essay, that first sentence leads into two or three other statements that provide details about the writer's subject or process. All of these sentences build up to the essay's thesis statement. New mandatory EEC - European Union (EU) directives regarding public participation in environmental impact assessment, and new national laws regulating city master plans, gave this and related cases a high profile as a test for all entities involved: Portuguese national government, local governments of Lisbon and Loures, the EU, private developers, and citizen's NGOs. Given the sensitivity of such kind of decisions, and also the strong reactions from citizens on the occasion of a previous process of siting a hazardous waste incinerator, both government agencies and environmental NGO's were strongly motivated to shift the focus of the debate from political and short-term considerations to a more technical and long-term reasoning. This created both a favorable condition for the introduction of new IT into the process, and the challenge of well defined expectations for the effect of these new IT. 7. Start with a definition of the term or the issue, then move on to your thesis. For example: The 1983 edition of The American Heritage Dictionary defines the word introduction as a noun derived from the verb introduce, which means "to preface." Knowing this certainly makes it easier to understand why introductions are such an important part of an essay. They give the readers a preview of the author's thoughts, and give them the background to understand what is to follow. A thesis statement is generally located near the end of the introduction. Sometimes in a long paper, the thesis will be expressed in several sentences or an entire paragraph.
