Classification and Division Essays

During their studies, students are frequently asked to divide and classify various objects or items and present their findings in essay form. Regardless of whether the task is to classify and divide some type of clothing in a job situation or for an essay, or categorize one’s living expenses in spreadsheet form for budgetary or tax return purposes, it is essential to know how to classify and then divide things properly.   

The Purpose of a Classification and Division Essay

The primary purpose of an essay of this type is to teach students how to think in a critical manner about how various things or categories of things relate to each other. Writing a classification and division essay is similar to other essays in many respects. It can help if the student looks at classification as the allocation of separate and unrelated items into distinctive categories or as individual parts of a whole entity. In a similar manner, division involves separating entire groups of things into different parts. These tasks are often so alike that it is not unusual for the terms to be interchanged by tutors and professors.    

Selecting a Suitable Topic and Preparing an Essay Plan

The writer needs to think about the purpose of their essay in order to plan it effectively. One starting point is to consider the essay’s tone. If a tutor requests a serious-minded topic that requires external research, it can help to start by considering categories within your discipline or field of study. For example, someone studying biology might consider categorizing dinosaur types into modern-day groupings.

For instant, the categories may include:

  • Those with characteristics that are bird-like
  • Those with reptile-type characteristics
  • Those with characteristics similar to warm-blooded mammals.  

Alternatively, if a tutor specifies a humorous or informal topic, the writer might consider things they observe in daily life. They may, for instance, consider the clothes stores at their local mall and categorize them according to type e.g. those that sell:

  • Children’s clothes
  • Adult clothes
  • Hipster clothes.   

From there, the writer could illustrate their various points using examples and/or their own observations.

Developing an essay plan means working out your classification and division criteria. If, for instance, the topic concerns arty styles in modern-day art, one could make a note of the main features of each artistic style, and from there, select the most renowned artists of modern times from each movement or style.

Introductory Paragraph and Thesis Statement

Your introductory paragraph should set out the topic and say why it is important to understand the various categories. The topic and the divisions or classifications should be explained in the thesis statement. 

Main Body (Supporting) Paragraphs

Each individual body paragraph should cover a category described in the thesis statement. If you were to take the earlier example of the dinosaurs, then one paragraph could talk about how some dinosaur species started to develop and display certain bird-like features such as feathers and other characteristics. These ideas should be supported with the use of external sources unless a tutor or professor permits the use of hypothetical or personally remembered examples. 

The Concluding Paragraph

Your concluding paragraph should reunite the categories or divisions, and their importance should be reiterated or explained again. For instance, it is important to understand how distinctive categories of dinosaurs evolved because it helps us understand the development of many modern animal species.

In order to make an integral assessment of people, places, or things, it is first important to have a complete vision of all of the elements that make it up. In understanding what the main types or kinds of a specific set, it is necessary to undertake a process of classification. Classification is a method of sorting “a group of things into categories or classes” (Duncan 1). For example, when analyzing the different ways of living that people have (namely urban, suburban, and/or rural), one incurs in a process of classification. Through classification it is possible for people to have a better understanding of the world that surrounds them. Classification consists of separating and organizing elements in order to be able to analyze and evaluate them (both separately and as whole). In principle it might not seem that classification is significant, but considering that everything that exists in the world is comprised of different elements, it becomes clear that such a kind of analysis, interpretation, and evaluation, is important.

Having introduced the concept of classification and stated its importance, it is important to discuss how classification is performed. In other words, what is the technique, or the steps, employed when incurring in a process of classification? First of all, it is important to select that which you intend to study and identify all of its constituting elements. Once this has been done, decisions have to be made regarding the way in which such elements will be organized, or grouped (into classes). When deciding what the grouping criteria will be, it is important to remember that there must be a common principle of selection between all of the aforementioned elements (a scheme that unites them) (Duncan 2). Once this has been done satisfactorily, it is important to go over the classification that was performed in order to make sure that no classes have been left out. For example, if a classification of the world’s religions is being done, the process would not be completely or correctly done if one religion were left out. 

Another prevision that must be taken into account when classifying is that the categories that the elements will be grouped under do not overlap. Each element should belong in one category exclusively. If at any moment one element can be assigned to more than one category there is an overlap and the process will end up being carried out incorrectly. Each category must be unique from the rest. Therefore, each one should be described in full, pointing out how it is that each one is different from the others and how each fits in the general scheme of the classification. In doing this, including an example when describing each category is always helpful. Finally, once the classification has been finalized it is advisable to evaluate each class/category, and if applicable, compare each one with the other classes/categories that make up the overall classification structure. This way, it will be possible to gain a better understanding of how each constituting element of the whole fits into the complete unit.

Classification is a process that helps in gaining a full understanding, a complete vision, of all of the elements that make up or characterize a group of people, a place, or a thing. In truth, everything that exists in the world is made up of a series of different constituting elements. Through classification one manages to visualize those differences, since classification basically breaks down the whole into its different parts. It is important, however, to be mindful that classification is not something that can be done arbitrarily. There are certain steps, or techniques, that are necessitated in order to render a good classification. Otherwise, the process will end up defeating the purpose of what classification truly is.
