Argumentative research paper:
The argumentative research paper consists of an introduction in which the writer clearly introduces the topic and informs his audience exactly which stance he intends to take; this stance is often identified as the thesis statement. An important goal of the argumentative research paper is persuasion, which means the topic chosen should be debatable or controversial. For example, it would be difficult for a student to successfully argue in favor of the following stance.
Perhaps 25 years ago this topic would have been debatable; however, today, it is assumed that smoking cigarettes is, indeed, harmful to one's health. A better thesis would be the following.
In this sentence, the writer is not challenging the current accepted stance that both firsthand and secondhand cigarette smoke is dangerous; rather, she is positing that the social acceptance of the latter over the former is indicative of a cultural double-standard of sorts. The student would support this thesis throughout her paper by means of both primary and secondary sources, with the intent to persuade her audience that her particular interpretation of the situation is viable.
