The science teacher showed me a number of his posts, and they would not have jumped out at me as being five-paragraph essays. In fact, he wrote posts that were four, six, and eight paragraphs also. Apparently, the teacher likes five-paragraph thinking as much as he likes the five-paragraph essay. In short, he just likes to make points and provide proof that his points are valid. He considers the five-paragraph essay to be the backbone of his writing. He says that people take his comments and opinions seriously, and that he is even a trusted authority in some places he posts. It seems that his readers focus on the points he makes and not the fact that he is using five-paragraph thinking.
