An in-depth understanding of the background of the research is necessary to conduct research. With poor knowledge, you cannot do research or write anything related to research. To gain more information, you need to read articles, journals, books, etc on a constant basis. Engage in discussions related to your research field may enhance your knowledge as well. Later, this knowledge would be useful for writing a good introduction to a science paper.
The first section needs to be written is the general statement of research. This question always pop-up in our mind when we begin writing, “What should I write in the first paragraph?”. If you are a college student and not use to writing, it could take days just to write a single sentence. So, where to start!
Identify keywords or keyphrases for the general statement
The research title should be the starting point to get the idea for writing a general statement for the introduction. Identify the keywords or keyphrases in the title and use it as a guide. For example, let’s say we have the following research title;
“Kinetic Study of enzyme-catalyzed reaction in the deep eutectic solvents”
The key phrase you should use is very obvious which is “Kinetic Study”, “Enzyme-Catalyzed Reaction” and “Deep Eutectic Solvents”. The sentences in the general should originate from these key phrases.
Constructive general statement
The general statement should be written in a constructive manner. This sub-section is actually a part of the introduction of your research. Before we proceed, please read how to write a good introduction for general tips on writing a good introduction.
For a research journal, the introduction is very short compared to the thesis. Hence, the general statement should be brief and comprehensive. It should have the following elements; opening statement, supporting statement and concluding remark.
The opening statement is the first sentence of your general statement. The sentence could be the definition, past history, origin, or fact related to the main key phrase or the keyword. Earlier, we have chosen 3 phrases. Set one of them as the main key phrases and then start writing your first sentence. For example;
“Deep eutectic solvents is a new class of solvent made of quaternary ammonium salts and hydrogen bond donor” – Definition
“Recently, enzyme-catalyzed hydrolysis of ester was successfully carried out in a deep eutectic solvent” – Past history
“Deep eutectic solvents is a biodegradable, safe and green solvent for chemical processes” – Simple fact
One sentence is sufficient. More than one could be used if the subsequent sentence is the continuity of the first sentence of the opening statement.
Afterward, you have to reinforce the opening statement with supporting statements. For example, the following supporting statement could be added to reinforce the first example of the opening statement;
“This solvent is formed by mixing each component with added heat. At a specific ratio, the melting point of the mixture is depressed and then forms a liquid at a lower temperature. The molar composition of the mixture which results in the lowest melting point is known as a eutectic point.”
The supporting statement should be more than one sentence. Obviously, Keep the sentences closely related to the key phrases in the opening sentence. Thus, the paragraph shall be fluid when being read.
Once you are done with the supporting statements, we need a concluding sentence at the end of the paragraph. “Conclude” here means how to end your paragraph and not making any conclusion.
There are two ways to make a concluding sentence depending on the cases. First is to link the paragraph with the subsequent paragraph, so the overall section is coherent. Secondly, the sentence is acting as a concluding remark for the overall section which normally applied to the last paragraph of a section (i.e., General statement of research).
Since, we only at the first paragraph, hence we should continue to develop the content for our general statement by adding more paragraphs. To be coherent, we should use the first concluding remark to end our first paragraph as follows for example;
“Deep eutectic solvent poses low vapor pressure and non-volatile, thus its application as a solvent for the enzyme-catalyzed reaction is encouraging”
As per the example, the concluding sentence above is intended to develop a new paragraph based on the second key phrase which is “enzyme-catalyzed reaction”. This way, it gives more opportunity for you to add more content while retaining the cohesiveness of the section. If you notice, a simple fact regarding deep eutectic solvent was used as a part of the concluding remark (“Deep eutectic solvent poses low vapor pressure and non-volatile”). Please keep in mind that definition, history, origin, and fact could be used anywhere in the general statement as long as its places correctly.
