You present a persuasive argument for the abandonment of the 5-paragraph essay and suggest a new format for presenting an argument... However, you did not provide much information on what is expected to go in between your introduction and conclusion? You suggested this format opens the essay to compare/contrast, cause/effect, analysis, etc... but how do you suggest students structure an essay with these approaches in practice? Any piece of writing needs some structure and main ideas that are then supported with various pieces of evidence (whether you are writing a historical thesis or a persuasive essay)... If you are abandoning a "main idea followed by supporting evidence" format, what do you propose should take its place? Or perhaps my understanding of the 5-paragraph essay you are speaking of is incorrect?
A teacher is called builder of the nation. The profession of teaching needs men and women with qualities of head and heart. There are many teachers in our school and a large number of teachers among them are highly qualified. I have great respect for all of them. Yet I have a special liking for Miss Y. Miss Y is a woman of great principles. She is jewel among all the teachers. Almost all the students respect her. She teaches us English. She is quite at home in this subject. She takes keen interest in teaching students. Simple living and high thinking is her motto. She is a woman of sweet temper and is always ready to help in difficulties. She treats us like her own brothers and sisters. She is an ideal teacher. It is these qualities of head and heart that have endeared Miss Y to the students and teachers alike. She is an ideal teacher in real sense of the word. She is the real model to emulate. May she live as long as there is sweet fragrance in the flowers?
