Argument Medic: Guidelines for writing
You need an argument that is publicly accessible (preferably on the internet) and that commits a fallacy. Once you have located an argument that commits one of the fallacies, you will write a short article that analyzes the argument. Your article, which should be modeled on the posts at the Argument-Medic blog (www.argument-medic.com), will identify the fallacy that the argument commits and explains how it does so. You are writing an analysis of a single argument, so your post needs to focus very narrowly on that argument. You are not taking a position on the larger issue(s) that the argument is connected to; you are only taking a position on whether the argument is well-founded (with a particular focus on identifying fallacies). With that in mind, your post should be written with the following structure in mind:

I.Introduction You should include a very brief introductory paragraph in which you give the relevant background information that gives the context of the argument. This would include identifying the author of the argument and the venue in which the argument appears. In addition you will want to give a brief statement that connects the argument to the larger issue which it concerns. A good rule of thumb is to provide as little information as necessary in order for the reader to understand what is going on with the argument.
II.Link to the source material You should provide a link (preferably using hypertext) to the original article (or video/audio clip) in which the argument that you are analyzing appears.
III.Embed some relevant portion of the original material In addition to the link that you provided in part II, you may also want to embed some portion of the original in your post. If the argument appears in an article, you can quote the relevant portion of the article that contains the argument. If the argument appears in a video or audio clip, you can, if you have access to it, embed a portion of the transcript. (Part III is optional, but it is a very good idea to do it if you can.)
IV.Paraphrase You should paraphrase the argument you will be analyzing into premise/conclusion format (since you have already identified the premises and conclusion, this part should be fairly easy). Here you are telling your reader what you take the author to be saying and giving the argument a more formal presentation by identifying the premises and conclusion.
V.Analysis
This is the heart of your post. Here you will be identifying the fallacy/ies that is/are committed in the argument. You need to name the fallacy, explain what the fallacy is, and show that the argument in question does indeed commit this fallacy.
