There is a "Title IX Research Starter" on enotes. Because I am not certain that is what you are referring to, I will list that as a link, just in case. An essay format, of course, is a different matter entirely. What I am going to cover is possible areas that you could address in an essay on Title IX, as well as essay format, which, I should note, is the same format you would use for any other academic writing.
First, as I brainstorm a bit on Title IX, several topics occur to me. First is that you could cover the history of Title IX, and how it came to be part of the Civil Rights Act. A second topic that you might write about is whether or not Title IX has been at all successful promoting equality for women in college sports. A third topic could be whether or not Title IX has made a difference in a kind of trickling up effect, for women in professional sports. Fourth, you might analyze the effects of the statute from a financial perspective, looking at how college sports are funded to begin with and how the additional requirement of sports opportunities for women has affected colleges and universities financially. Finally, you could examine the case law that has interpreted Title IX, discussing its legal principles and applications. This is by no means an exclusive list of possible topics, but enough, I hope, to get you started thinking about topics.
An essay that you write in school must have a structure that is the same as the structure for any essay in academic writing, including an introduction, body paragraphs, and a conclusion. Let's look at these in more detail.
The introduction should gain your reader's attention, draw your reader in to the "world" of the essay, provide enough background and context for your reader to understand the content, and to state your thesis and supporting points, which is what we call the thesis statement. The thesis statement states your main idea and acts as a kind of outline for all your content as you write it, as well as acting as a kind of table of contents for your reader. It is best placed at the very end of your introduction. So, for example, while I do not know that I would take this particular stance or that my supporting points would even be true, here is a thesis statement for an essay on Title IX:
Title IX has been a failure in its goal of creating sports equality for women because a backlash has created prejudice against females, because schools have chosen to cut back on male sports, rather than to include more female sports, and because the representation of females in the professional world of sports has not changed one iota.
My thesis would be that the statute is a failure, and I would have three supporting points for that thesis. Every introduction needs the elements I have described above and should end with a thesis statement.
Body paragraphs are meant to provide evidence of your supporting points, one paragraph at a time, in the order in which those supporting points are listed in the thesis statement. Thus my first body paragraph would be about the backlash, my second would be about the cutback in male sports, and my third would be about the representation of females in professional sports. For each body paragraph, you should begin with a topic sentence, one that explains the point of the paragraph and how it connects with the thesis. For example, my first body paragraph could begin with this:
One reason Title IX has not been a success is the backlash it has created against female athletes.
Now the reader knows exactly what my paragraph is going to be about.
How does one develop the body paragraph? You are expected to provide evidence. This can take many forms. It can be anecdotal, it can be "expert" evidence, it can be statistics, or it can be logic-based. In academic writing, though, you are always expected to provide evidence, not simply statement after statement of your own opinions. You are also expected to stay on point, not discussing more than one point or idea per paragraph and not discussing the topic of another paragraph.
A conclusion is meant to wrap it all up in a neat little package for the reader. You need to remind the reader what your thesis is and review for the reader the points you have made to support that thesis. No new points should ever be mentioned in the conclusion, since they have not been developed in any way in the body paragraph. Sometime a conclusion projects forward into the future, for example, suggesting future implications or improvements.
Your paper need not necessarily be one in which you make three supporting points and have three body paragraphs. Many papers have fewer or more. This is meant to be an example of the structure of the academic essay, though, and that basic structure should be the same, whether you have two body paragraphs or twenty body paragraphs.
Think about the topic you wish to pursue concerning Title IX, and do some research on that topic. Then you will have some ideas about what your thesis statement is going to be. You can then begin to develop body paragraphs that are about the points of support. Quite often, introductions and conclusions are not written until after the body paragraphs are written, and many students find it easier to begin that way than to try to begin with an introduction. I am certain you will find a good area of discussion about Title IX. Good luck!
