State your main idea explicitly in nonfiction

My friend handed me a book of nonfiction her uncle had written and asked me for my opinion.  I scanned through the first few pages and handed it back.  “He doesn’t say what the book is about.  I have no way to evaluate the book without knowing what his point is.”

If you are writing a nonfiction book, essay, chapter or news story, you should alert the reader to your purpose.  You can do that several ways.

One way is to write a headline or title which encompasses the main idea.  “Twenty dead in tornado” and “Biden wins Pennsylvania’s electoral college votes” clearly state the main details of the article to follow.

Another way is to state in the first paragraph (or rarely, in the last, if you are leading up to your main point) the thesis of your writing.  A classic example is the following:  “Oppressed people deal with their oppression in three characteristic ways.” –The first sentence from “The Ways of Meeting Oppression” by Martin Luther King, Jr.  The rest of his essay identifies those three ways and explains why one is best.

If you are writing a book, use your introduction to explain to your readers what the purpose of your book is and what they should learn.  “You’re reading this book because you want your business to grow. I’m going to show you a proven system for making all this happen.  –The Snowball System by Mo Bunnell

If your readers need to infer the main idea, they might stop reading.  Too much work.  So make sure you state early on what your point is.

Ten ways to know if a “thesis” is really a thesis?

A thesis is a declarative sentence, never a question.  “Who was the best US President?” is not a thesis because it is a question.  “Washington was the best US President” is a thesis providing the word “best” is precisely defined.  If “best” is not precisely defined, then this is not a thesis because “best” is vague.

A thesis is not a statement of facts which can be verified.  “Washington is the only President to be elected unanimously” is not a thesis because research shows this is a factual statement.

A thesis is not an opinion of personal taste.  “I need to attend college” is not a thesis.  It cannot be researched scientifically.

A thesis is stated positively, not negatively.  “Washington was not the best US President” is not a thesis.

A thesis does not use biased or untruthful language.  “Dangerous hand guns should not be sold” is not a thesis.  “Dangerous” is a biased word.

A thesis uses precise language.  “Some amphibians should be put on the endangered species list” is not a thesis.  “Some” is not precise.

A thesis is about one idea, but that one idea can be subdivided.  “The US Civil War had two causes:  slavery and states’ rights” is a thesis.  This thesis is about the causes of the Civil War (one idea).  “Roses are easier to grow than irises but harder to grow than day lilies” is not a thesis.  It contains two separate ideas.

A thesis is researchable using scientific evidence or the scientific method. “Nothing escapes black holes” is not a thesis.  Scientific research has proven this statement to be false.  “More two-year-olds today are fat than in Boston in 1776” is not a thesis because it is impossible to research how many two-year-olds were fat in Boston in 1776.

A thesis deals with real, not conditional or hypothetical information. “If Elvis were alive today he would be a billionaire” is not a thesis because Elvis is not alive today.

Where should a student start an essay?

If you are teaching children essay writing, at which point do you tell students to begin their writing?  With the hook?  With the introduction?  With the thesis?  Somewhere else?

Lately when my students start to write essays, I tell them to skip over the introduction completely for now except for its last sentence, the thesis.  That is where I tell them to begin.

Then I tell them to write the topic sentences of the body paragraphs.  After that, I tell them to fill in the body paragraphs with detailed sentences.  Then, after the student knows the contents of the body, I tell students to write their introductions at the top of one page and their conclusions at the bottom of that page, so the students can see them both together.

The first draft of an essay is put together something like this (after the student writes an organizer):

  • The thesis is written at the top of the notebook paper or computer document.
  • Under it is written the first body paragraph topic sentence. About 2/3 of the way down the notebook paper is written the second body paragraph topic sentence.  On the back top is written the third body paragraph topic sentence.  Half way down is written the fourth, if there is a fourth.  If the student is using a computer, these sentences can be written one beneath the other since inserting more material is easy.
  • At this point, I ask the students to check to see if each topic sentence supports the thesis. If not, this is the time to make it work.
  • Next, the students fill in the body paragraphs with details from their prewriting organizer, making sure that each detail supports the paragraph topic sentence.
  • Finally, on a separate notebook paper (or at the top of the essay), students compose the introduction with or without a hook.  Below it, the student composes the conclusion, trying as much as possible, to pick up some thread mentioned in the introduction.  If the student is using a computer, the student can move the conclusion to the end once he or she has compared it to the introduction.

At this point students can type a rough draft if they have worked on notebook paper, assembling the paragraphs in the correct order.  Once the essay is on computer, they can revise.

Students tell me that at school they are told to start writing essays with the hook.  I tell my students to skip right over that.  Why?  What I am looking for is not creativity but logic, the logic of topic sentences which support a thesis and paragraph details which support the topic sentences.  That is the meat of an essay, and that is what I see missing in students’ essays these days.  When that logic is established, the student can work on a creative (or not) introduction and a conclusion which dovetails with that introduction.
