To explore whether the IMRaD structure is commonly used in our community, I examined the 100 papers published in JM3 in 2013. I found that 78% of them employed some variation of the standard IMRaD organization. About half of these separated out theory from the methods section, which was the most common variant. Other variants included separating out the motivation from the introduction, separating future work from conclusions, separating results from discussion, and breaking up a long section (such as theory or discussion) into separate parts. Only one paper did not have an Introduction section, and only one (different) paper did not have a Conclusion section. The 22% that did not employ the IMRaD structure generally employed a structure that was more specific to that work, using descriptive headings that did not fall into the “methods” or “results and discussion” categories. One interesting structure created two parallel sets of sections, one for experiment and one for modeling.
