Turning around student achievement through structured writing

Several years ago, a high school principal investigated why so many of her students were failing.  After staff-wide research, the reason became clear:  bad writing, an inability to turn thoughts into sentences, paragraphs and essays.  A rigorous program of writing in every subject except math ensued, and within two years, final statewide exam scores rose 10 to 20 points.

Teachers began this new program by teaching a simple skill:  how to turn ideas into simple sentences.  When students could do that, they learned how put ideas into compound and complex sentences.

Students learned how to identify the main idea in a paragraph next, and then how to write a paragraph with a main idea.  Once paragraphs were mastered, it was on to essays, learning how to develop an introduction and controlling idea (thesis) and how to write body paragraphs to back up that controlling idea.  Students learned how to incorporate details into their writing, especially examples.

What students were taught was to think critically through structured writing—a point of view with facts to back it up.  To do it well takes planning and organizing ideas.  It is the kind of writing which the Common Core State Standards expects all high school students to master.

To find out more about this amazing success story at New Dorp High School in Staten Island, go to Peg Tyre’s article in The Atlantic.  Though it was published five years ago, the story–and the method to improve thinking through structured writing–is just as relevant today.  https://www.theatlantic.com/magazine/archive/2012/10/the-writing-revolution/309090/

What is a weak thesis?

Many students don’t know the difference between a weak thesis and a strong thesis.  Here are some clues that show that an essay’s thesis is weak:

A thesis is weak if it is already known to be true, so there is nothing new to be explored.  For example,

  • Smoking is bad for human health.
  • Benjamin Franklin was an 18th century inventor.
  • The New England Patriots are a great football team.

A thesis is weak if it is a personal belief, not something to be investigated.  For example,

  • Summer is the best season.
  • Middle school is harder than elementary school.
  • Abraham Lincoln ranks number one among US Presidents.

The thesis is weak if it is too broad to be thoroughly investigated.

  • Hurricanes are dangerous storms.
  • Nancy drew books appeal to girls.
  • Romeo and Juliet is a tragedy.

The thesis is weak if it does not make a claim needing to be proven.  For example,

  • Dr. Seuss wrote popular children’s books.
  • Being a police officer is both good and bad.
  • In chess, each piece moves in particular ways.

The thesis is weak if it is not controversial, not a statement over which people can disagree.

  • Barak Obama was the 44th President of the US.
  • No human being has lived for 130 years.
  • Alex Fleming’s discovery of penicillin mold was one the greatest medical discoveries of the 20th century.
