A <\/span>research rationale<\/span> can be defined as an overall explanation for why you are conducting your research. This reasoning sets the context for your readers and includes the existing scenario and any identified gaps in your chosen field, which you are proposing to address through your research findings. In other words, a <\/span>research rationale<\/span> answers the \u201cwhy\u201d regarding your research. A good <\/span>research rationale<\/span> should be concise, persuasive, and clear and should sufficiently communicate your arguments for conducting the research.\u00a0<\/span>\u00a0<\/span><\/p>\n

A well-written <\/span>research rationale<\/span> can provide a justification to your readers about the novelty and relevance of your research. The <\/span>research rationale<\/span> should be able to convince your readers about the reasons for which you undertook the study and the methods you have undertaken. In addition, a persuasive rationale also indicates to readers your expertise and understanding of the specific subject and lends credibility to your study. This would in turn help other researchers in the future who may want to refer to your findings for further research.<\/span>\u00a0<\/span><\/p>\n

This article discusses the importance of drafting a clear and convincing <\/span>research rationale<\/span> to help readers understand the significance of your study and the reasons for which you have conducted or propose to conduct the study.<\/span>\u00a0<\/span><\/p>\n

What is a Research Rationale<\/span><\/b>?<\/span><\/b>\u00a0<\/span><\/h2>\n

A persuasive <\/span>research rationale[<\/span>1,2]<\/span> is essential for communicating the novelty and importance of your research with readers. In a research paper, the rationale is usually included as a part of the introduction where the existing research and gaps are discussed. This section provides a background and sets the context for the readers. While a <\/span>research rationale<\/span> is also referred to as the research justification, it differs significantly from a problem statement, as shown in the table below.<\/span>1<\/span>\u00a0<\/span><\/p>\n

Research rationale<\/span>s are typically included in various academic literature, including research proposals, journal articles, dissertations, grant applications, and conference papers. A well-structured <\/span>research rationale<\/span> should be clear, concise, comprehensive, and relevant. Its length can vary depending on the type of academic text where it is included and the publisher guidelines. The rationale is usually positioned at the end of the introduction section or in the background section. The following table lists the typical length as a percentage of the total word count.[<\/span>1]<\/span>\u00a0<\/span><\/p>\n
