Analytical writing is usually the most common category chosen. Since the writer is faced with the task of breaking down and thoroughly explaining a topic, this type of thesis is very easy to construct.
In order to do this, students should focus on "how" and "why" the topic and idea work. Students should keep in mind that the goal is to provide a specific claim, as well as demonstrate a deeper understanding and knowledge of this statement.
An argumentative thesis requires a little more work, since the point of the writing is to convince the reader and urge him to do something. Although it requires a similar approach to the analytical process, in terms of defining a problem and finding a reason or evaluation for this, this type of thesis requires a thoroughly examined paper with counter-arguments.
To complete this sort of statement, students need to make a specific claim and support it with strong evidence. It means taking a well-founded position, whether it's an opinion, proposal or interpretation, and defending it to the end with solid facts and figures.
When it comes to the expository thesis, the goal is to explain an idea or topic to the audience. It is the most organized of the three structures and types, since it is listed with a specific outline for the audience to follow.
Although it sounds simple enough, students should keep in mind what they're trying to explain and how to best organize their explanation accordingly. Also, the order of how the idea should be presented is important with related categories and sections. Along with this, as usual, the student needs to have strong facts and research to support her claim.
