A well-structured article helps readers find the information it communicates and to easily follow the authors’ methodologies and arguments. To help do this, most articles follow a common pattern and structure called IMRaD. In this section, we’ll discuss what this means, how to do it, and how it will help your manuscript.
Overview of IMRaD structure
IMRaD refers to the standard structure of the body of research manuscripts (after the Title and Abstract). This consists of:
- Introduction
- Materials and Methods
- Results
- Discussion and Conclusions
Not all journals use these section titles in this order, but most published articles have a structure similar to IMRaD. This standard structure:
- Gives a logical flow to the content
- Makes journal manuscripts consistent and easy to read
- Provides a “map” so that readers can quickly find content of interest in any manuscript
- Reminds authors what content should be included in an article
- Provides all content needed for the work to be replicated and reproduced
Although the sections of the journal manuscript are published in the order: Title, Abstract, Introduction, Materials and Methods, Results, Discussion, and Conclusion, this is not the best order for writing the sections of a manuscript. One recommended strategy is to write your manuscript in the following order:
- Materials and Methods
- Results
- You can write these first, as you are doing your experiments and collecting the results.
- Introduction
- Discussion
- Conclusion
- Write these sections next, once you have had a chance to analyse your results, have a sense of their impact and have decided on the journal you think best suits the work.
- Title
- Abstract
Write your Title and Abstract last as these are based on all the other sections. Following this order will help you write a logical and consistent manuscript. Use the different sections of a manuscript to ‘tell a story’ about your research and its implications.
