A written presentation is a text that is prepared to convey information or knowledge about a specific topic. At school, the purpose of an exhibition is to disseminate knowledge to the rest of the class and for the student to show mastery of the subject to the teacher.
The written presentation generally supports the oral presentation and is often supported by audiovisual material (billboards, maps, digital slides).
The presentation is generally made with the intention of explaining or presenting a topic, so it must be done using clear and precise language, thinking about the oral presentation.
The language of the exhibition must be clear and precise, so that it can be understood by readers and listeners, without any frills or unnecessary adjectives.
The information must be presented clearly, depending on the subject, place places and dates if they are important, and rely on audiovisual material if possible. Exhibitions in educational centers generally deal with historical, social and scientific topics.
The topic or content must be well structured to be understandable, with introduction, development and conclusion.
The structure may vary according to the theme. For example, if it is a biography or a historical event, it is convenient to use chronologies or timelines; if the topic is developmental biology, we must talk about organs and functions.
As it is support material, it is convenient to put short sentences, which remind or indicate the topic that will be developed orally. When possible, it is also advisable to use drawings, illustrations, etc., that help to understand the subject.
Written expositions are present in didactic texts, journalistic articles, encyclopedic articles and academic and scientific journals.
There are at least three types of exposition according to the way in which the information is to be presented: narrative, descriptive and argumentative.
It is one that is used when narrating historical events, the lives of characters or romantic stories. For example, when the subject is: "Life and Work of Don Miguel de Cervantes, soldier and writer (1547-1616)".
It is used when the subject belongs to a scientific discipline, such as biology, physics or chemistry. They are exhibitions that address a topic or object in a general way and then describe it in parts. An example: "The digestive system: organs and functions".
The argumentative exposition is suitable when dealing with social or philosophical issues, where concepts and opinions should be exposed, or reasoning developed.
Argumentative expositions are those that deal with topics such as democracy, materialism versus idealism, pros and cons of sex education, abortion, etc..
Once the topic has been selected, the steps to prepare a written presentation are as follows: Research and documentation, and writing of the exhibition (title, exhibitor data, introduction, development, conclusion and bibliographic sources)
Once the topic has been chosen, it is time to find the information and support material. Currently the information on the internet on any subject is overwhelming, but not always reliable.
To guarantee reliable information, use recognized links according to the subject, such as Cervantes Library, Real Academia Española, BBC, National Geographic, Nature, etc. You can also rely on traditional publications, such as newspapers, magazines and books.
If you are going to use pages like Wikipedia, it is always recommended that you contrast or confirm the information with another recognized trajectory page.
It is important to take care of the spelling, if you have doubts you can go to a traditional dictionary, or consult the ones found on the internet. You should also take care of the presentation (without smudges or erasures).
Exposures are usually made on large sheets of paper, if you do them manually. If you do them on a computer, you can opt for a slide show, like PowerPoint.
Generally, the title of the exhibition is chosen by the teacher. In this case we use as an example "Our cousin the chimpanzee".
You must put your full name and that of your colleagues, if it is a team; date and name of the school; grade or section in which you study.
In the introduction the topic is presented in a general way, indicating what the exhibition is about and what it intends to cover.
Being the subject the chimpanzee, you can mention its scientific name (Pan troglodytes), places where you live and what is your relationship with us. You can start the presentation with a question:
"Did you know that the chimpanzee shares 98% of the genetic code with us, and that is why some biologists call the human being the 'third chimpanzee'?".
Write the presentation using your own words, and when copying verbatim use quotation marks.
It is the bulk of the exhibition, in which the main information structured in main and secondary ideas is presented. This section presents the main information, accompanied by descriptions and arguments, when necessary..
The data to be highlighted are placed; in the case of the chimpanzee, its physical appearance, social behavior, abilities that resemble humans, etc. Information should be provided in short, clear sentences, in short paragraphs.
The text must be coherent, that can be understood by any reader, and have cohesion, with phrases and sentences properly linked, for which you can rely on connectors, that is, expressions that serve to connect sentences.
If you are going to copy verbatim from one of the sources, you must use quotation marks, and indicate its origin. For example:
"The males weigh about 80 kg in captivity and measure up to 1.7 m. It is characterized by its advanced intelligence, often compared to that of human beings ”(Wikipedia).
Ideas are taken from the introduction (the relationship of the chimpanzee with humans), and we can talk about the current situation of this species (in danger of extinction).
When placing the sources used, first mention the author by his surname, then the year of publication, followed by the title of the article or work (which can go first if there is no author); and then data from the publisher or the website.
Following the example of the chimpanzee exhibition, these would be the sources used:
