There are currently numerous style manuals that contain rules and recommendations for the preparation and presentation of scientific documents. Among the most widespread standards we can quote: the Council of Science Editors (CSE) style and the Harvard System of Referencing, widely used in biology, physics and chemistry; The Chicago Manual Style, widely used in history and law; the IEEE Standards Style Manual, used in engineering, computer science and technology; the MLA Handbook for Writers of Research Papers, common in literature, arts and humanities publications; the Publication Manual of the American Psychological Association (APA), frequently used in the social and behavioral sciences; and the Uniform Requirements for Manuscripts Submited to Biomedical Journals (URM) or Vancouver format, applied by the main biomedical journal publishers. Each of these manuals offer specific guidelines that logically conform to the conventions of the different scientific fields. Among other issues, they tend to address aspects such as the structure and organization of the manuscript, indications for presenting tables and figures, the format of citations and bibliographic references, and even offer ethical, legal and deontological recommendations. Among scientific journals of educational research, the adoption of the APA publication manual is widespread. Proof of this is that the 10 Spanish educational journals with an international impact factor in the 2021 edition of the Journal Citation Reports (categories of Education & Educational Research, Education, Scientific Disciplines, Education, Special and Psychology, Educational) refer in their guidelines for the submission of manuscripts to the indications contained in this manual. In the specific case of Education XXI, it is expressly indicated that, in the preparation of the manuscript, authors should follow the APA publication guidelines in its 7th edition.
