Writing is one basic and important skill one should have in order to communicate, whether it be for the humanities, sciences or business. Under these various disciplines or fields where writing is required, we need to determine which writing pattern is best to use. The Humanities may involve writing literature reviews, book reports, literary analyses, essays, critical reviews, and argumentative papers. The Sciences have natural, social, formal and applied science. Writing for this discipline calls for precise use of terms, simple and direct language, objectivity and clarity. As for Business, we have memos, claim letters, economic research papers, résumés, school application essays, scholarship application letters, and business proposals. There are things you may want to write first before speaking since writing will give you more time to think of what you want to say. As a student, you may have already encountered different writing tasks. By this time, you may have also developed your own way of expressing your thoughts through writing. Composing paragraphs, essays or short answers for your homework are some of the instances when you have to write. When you write, you need to know your reason. Why do you need to write? What are you writing for? This sounds a little difficult in the beginning. That is why it is necessary that you organize your ideas first. How do you organize your ideas? Arranging your thoughts will depend on the purpose you have for writing, hence, there are patterns of written texts across disciplines. The different patterns of development of these written texts across disciplines will help you find the direction of the thoughts and ideas you write. Some of the patterns may have similarities and differences that distinguish one from the others. To help you tell apart a specific pattern, look into the distinctive characteristics it has.
