The Introduction consists of four fundamental parts, i.e., a short review of the main subject of the study, the shortcomings of previous studies, the aim of the study and the scope of the study.
The short review
The introduction must start with a short review that outlines the core of the subject. The review should be concise, interesting and informative. Long historical reviews are dull. The review varies in length from one sentence to several paragraphs, and it should be supported by the major and more recent references. Nevertheless, do not use too many references, as these are more suitable for the later discussion.
Shortcomings of the existing studies
The author should convince the reader of the importance of the study by giving reasons for investigating this particular subject. This could be achieved by addressing the problems, limitations and shortcomings of previous studies.
The aim of the study
The study should answer a timely and important question, the rationale of the study must be strong and very clear, and the results should be an addition to the existing knowledge.
Scope of the study
At the end of the introduction there must be a short paragraph setting out the scope of the study, providing a quick overview of the organization of the study that follows.
