I have been teaching English to young Japanese students. A Japanese junior high school student explained to me the difference between an introduction and conclusion using this hamburger drawing.
The challenging for Japanese students is that we do not repeat thesis statements in both introductions & conclusions in Japanese essays. It is one of the differences between English and Japanese essays.
She explained English essays as:
The top bun is an introduction. The sesame seads are important ideas for the essay, (thesis statements).
The bottom bun has the flavors soaked. The most important discussion is the meat, and then tomato, lettuce... But in the conclusion, all flavors are contained, which is a reminder of the introduction & additional flavors for the conclusion.
My other Japanese students (around 10 years old) also have been studying English composition.
The main challenge for Japanese students is that the main thesis is at the end of Japanese essays, but English essays have the thesis in the introduction. It took me forever to understand this concept.
In the last class, each student presentated their thoughts on the English composition style.
One student said,
"English composition is like a snake. The most important thing is located on the face & introduction. The body has stripes, which represent paragraphs. And each paragraph has one color, which means one topic."
Again, they are so genius.
English Composition is a Snake!
