I would like to know how to write a scientific introduction paper. Since I should write four to five introduction for my thesis dissertation. How could I write unique introduction for each paper?
If I may, after having written many articles and having consequently been myself counselled on this issue by many examiners, I could offer the following suggestions
The introductory abstract should not be too long and should summarize the object of thesis.
The introduction section should go into more details. For example present a historical overview of the formal research on which the development that you will be proposing is grounded, and that you will also refer to later. A summary of the new development that you will be explaining in the main section, and the general order in which the various steps of the development to come will be presented. This way, the examiner will have a clear general preview and understanding of the development to come, increasing his/her interest.
The main body of the thesis goes into full detail of each step presented in the introduction, which now serves as a guide as to what must be described.
The conclusion summarizes the new contribution that this new development brings to the established body of research presented in the intro, possibly highlighting also the most important aspect of this new contribution.
During the process, you can expect to have to hugely modify numerous times each previously written section as your description progresses, due to some aspect becoming clearer and clearer as you go.
Typically, researchers write the introduction last, despite it being the first chapter, because a comprehensive understanding of what's being introduced is needed. This approach allows for a better perspective on the research project as a whole, including initial questions, methodology, results, and conclusions. The introduction serves to provide readers with an overview of the research, setting expectations for subsequent chapters without requiring in-depth details, which will be explored later.
Repetition and redundancy can pose challenges, affecting both the overall paper and individual sentences. Nevertheless, it's important to note that repetition can serve a useful purpose when employed effectively to aid the reader's comprehension. At its core, it's advisable to refrain from duplicating entire sentences or paragraphs across various sections of the paper, as such redundancy is generally not well-received by readers.
Avoid restating previously covered points.
Ensure that you do not use the same heading more than once.
Evaluate the relevance of all sections with respect to the paper's primary objective.
