Writing styles are a matter of culture and language. They often vary among people. I have some experience with this, and I wrote about my challenge in Languages & Life Lessons.
This variety in style and organization of content often becomes more obvious in people who have learned writing in one country and then move to a country with a different style of writing.
I felt confused and frustrated when I moved to Iran after spending my school years in a French education system. I didn't understand why my teacher in Iran didn't like my compositions, which I now know were written in a European writing style, and why I failed to get good grades despite my efforts.
Students who have learned writing, or academic writing, in other countries have likely learned to organize their contents in a specific order and may have trouble following the organization in the American writing style. The same way, an American may have trouble following the flow of ideas in a text written by an English learner because it is not just the style of the writing that varies but also the style of the organization.
For me, not knowing about the contrast among writing styles made the writing experience quite dreadful during my school years. Once I understood that writing styles varied in different countries, my frustration went away. I then practiced and learned to write effectively in each style.
