IMRaD (Introduction, Methods, Results, and Discussion) seems to be the standard structure of scholarly journal papers.
Are there also alternative standardized paper formats that are known to obtain widespread acceptance among scholarly journals?
(Not counting minor IMRaD-modifications, such as the addition of a "concluding" section after the usual IMRAD-structure.)
The background to my question is the following: I teach academic writing to students from a variety of disciplines, mostly from chemistry, computer science, physics, engineering, but also social scientists and even a few from the humanities. It is quite a mix. I use IMRaD, and while most students quickly embrace that structure, some students express their concern that IMRaD is not apt to their purposes; usually, by the end of the semester, they do acknowledge, however, that IMRaD eventually helped them. I am nevertheless wondering whether I can accomodate to such students in the future by allowing them to use a paper structure other than IMRaD, but the format should still be one that finds conventional use in the system of science.
