A good thesis statement will let your reader know what your essay is about and what your position is on that topic. Sometimes we also include in a thesis statement a bit of a "preview" of how we will support our opinon.
Let's look at an example:
Suppose I were writing an essay on President Obama's effort to reform healthcare. I would have to let the reader know that was what my paper was about. I would also need to let the reader know my position. In the thesis statement, I can also let the reader know what points I am going to make to suppport my position. Here is one possible thesis statement I could create:
President Obama's efforts to reform healthcare should be supported because people should not have to make choices between eating and seeking medical attention, because unhealthy people harm the economy, and because no other civilized country fails to provide healthcare to its citizens.
Do you see how, in just one sentence, I have told the reader I am going to be talking about President Obama's healthcare plans, my position on those plans, and the reasons I have taken this position?
You can use the same strategy to create a thesis statement about your position on sex education in school. Good luck!
You must first identify what type of argument you would like to make. According to Aristotle there are three different types of arguments to which you can formulate your thesis. They are: Emotional appeal ( appeal with your heart), Ethical appeals ( support moral character and credibility), and Logical appeals ( deal with facts, research and experimentation). Once you decide which one is closer to what you would like to present, then you can create a thesis statement that will or will not support your topic.
The topic of sex education for public schools is sort of a broad topic. There are several ways that you can develop your hypothesis/question. These are some that I thought of: using data and statistics from teenage pregnancy, heated debates in the political arena or the positive outcome of teaching it and how it will later have an effect on society.
My suggestion would be to look at some articles and some of the research that has been presented and then formulate your own ideas on what you think would be a great issue to study.
A thesis statement in a thesis is generally a proposition or statement, which is examined in detail in the thesis, and the truth or otherwise of the statement is ascertained. Therefore, although a thesis statement may support sex education in public school, the conclusion of the completed thesis may not. Here it should be noted that the thseis involves some amount of investigation and research, and the thesis statement is finalized before start of the investigation and research. Thesis statement intended to give a direction to the research rather than indicate results of the research. Therfore the validiy or otherwise of thesis statement cannot be confirmed at the time of formulating it.
Coming to suggesting a specific thesis statement, i suggest the following:
"Sex education in public schools will lead to healthier sex behavior among the students in their later lives."
An alternative thesis statement could be:
"Sex education in public school leads to greater incidence of pre-marital sex."
While writing an essay, rather than a thesis, it will be more appropriate to talk of the subject of the essay. one suggestion on what this could be is:
"Benefits of Sex Education in Public Schools"
