Transcript of Technical Writing
• A genus is a class; a species is a sub-division within a class. If chemistry is the genus, organic chemistry and bio-chemistry are the species.
•The initial step in classification brings together related items; it forms groups from individual items. Definition The foregoing discussion has suggested why classification is a useful technique of exposition: When is Classification a useful expository technique? -it permits a clear, systematic presentation of facts. When to use this technique depends on whether a writer is dealing with classifiable subject matter and whether his or her writing can be made more effective by means of the technique. Classification, then, is useful when you have a number of like things to discuss, among which there are points of similarity and difference which is important for the reader to understand. Obviously, however, the relationship among the things classified must be a significant one. Suggestions to follow in presenting a classification in using classification as an effective way of presenting related facts, it is helpful to follow a number of “rules,” all of which are simply commonsense suggestions for clarity and meaningfulness. For example, in classifying roses, color may be the significant guiding principle for the classification. According to effectiveness, mines may be classified as contact mine, magnetic mine, acoustic mine, and pressure mine. Engines may be classified according to make, use, speed, number of cylinders; but only one of these at a time should be used. Failure to limit oneself to one basis at a time results in a mixed classification. Rules in Classification Here are some rules to follow in classification. 1.Make clear what is being classified. This principle requires a definition of the subject which may not be familiar with the reader. For example, "renewable" and "non-renewable" resources have to be defined before such matters as cotton, tress, rubber, and animals can be classified under the former and iron, gold, copper, lead, zinc and mercury under the latter. 2. Choose and state a single, useful basis or guiding principle for the classification and stick to it. This principle requires a definition, description, or illustration of species be given. Characteristics peculiar to that one sub-classification alone should be discussed fully. Rules in Classification 3. Name all species according to a given basis. 4. Make sure that each species is separate and distinct; that there is no overlapping. Classifying teachers according to their academic rack - instructor, assistant professor, associate professor, and full professor is separate and distinct but adding to this another species , like proficient teacher, will result in overlapping. 5. Help the reader understand the distinction between species. You don’t need to be urged to break down a subject for purposes of discussion. You would do it anyway, since it is a natural, almost inevitable, method of procedure. After all, a writer is forced into subdividing subject matter for discussion because of the impossibility of discussing a number of things simultaneously. What is emphasized is that logical and effective principles in carrying out such divisions should be followed. A Note on Partition Earlier we defined the term “partition”; now we will comment briefly on the use of partition in exposition. Classification, as we have seen, is a method of analysis ( and exposition) that deals with plural subjects. You can classify houses, for instance, by considering them from the point of view of architectural style, principal material of construction, number of rooms, and so on. But you cannot classify a house except in the sense of putting it into its proper place in a classification that deals with houses. You can analyze a particular house, however, by naming and discussing its parts: foundation, floors, walls, and so on. This analytical treatment of a single thing (idea, mechanism, situation, substance, function) is called “partition,” or simply “analysis.” As you know, it is a familiar and useful way of dealing with a subject. Those classification rules that were discussed also apply to partitioning. A Note on Partition A complete classification based on one principle requires the listing of every known species. In classifying dogs, for instance, all commonly known breed should be included. Classification:
According to fuel consumption, cars can be categorized into two types, hybrid cars and regular cars.
-This is an example of classification because it divides a group of items (cars) into a smaller number of group which is hybrid and regular cars
There are four major features of a hybrid car: a small fuel-efficient an electronic motor and automatically rechargeable batteries.
-This is an example of Partition because it breaks down a unit (hybrid cars) into its component parts Examples Elements of a Classification/Partition Sentence The subject is the item/thing that we want to classify or partition In partition, they are the parts, steps of a process, features, or characteristics of the subject. Sometimes with classification, the basis of classification is given. It is usually introduced by the phrases “according to,” “depending on,” or “on the basis of.” The items: In classification, they are the classes, types, categories, or groups of the subject.

2. Four forces act on an airplane. They are weight, lift, drag, and thrust.
3. To specify the state of a gaseous substance completely, we must cite the values of four variables: volume, amount, temperature, and pressure.
4. Computer systems are typically classified as microcomputers, minicomputers, and mainframes on the basis of their computing power.
5. In nature, water goes through a number of steps. They are water on Earth, vapor rising into the atmosphere, cooled vapor, and water coming back to Earth as rain. http://www.onlineacademicwriting.com/documents/Classification%20and%20Partition_%20sentences_%20Abdurahman.pdf
