Post-Publication Corrections

After an article is published, situations may arise that require adjustments, clarifications, or specific editorial actions. In these cases, the editorial team of Educação Matemática Debate will carefully analyze the request, ensuring that any changes are conducted in accordance with SciELO guidelines and the ethical principles established by the Committee on Publication Ethics (COPE).

Except for minor and strictly formal corrections, any modification made after publication will be accompanied by a post-publication notice, permanently linked to the article. These notices may take the form of an addendum, erratum, expression of concern, retraction, or removal.

The purpose of linking post-publication notices to the article is to ensure editorial transparency, preserve the integrity of the academic record, and ensure the reliability of the scientific production published in Educação Matemática Debate. All post-publication notices will be made available in open access from the date of their publication.

Authors, researchers, readers, or representatives of research institutions or research funding agencies must notify the editorial board as soon as possible of the identification of errors, inconsistencies, or any problems in already published articles, especially those that may compromise the interpretation of the data, the validity of the analyses, or the reliability of the information presented.

It is the responsibility of the corresponding author to ensure consensus among all co-authors before requesting any type of correction or editorial expression.

The procedures relating to addenda, errata, expressions of concern, retraction, and removal will follow the SciELO Registration and Publication Guidelines, using the CrossMark tool.

If, after reading the policies below, any editorial action is necessary, the editorial team of Educação Matemática Debate should be contacted by email at revista.emd@unimontes.br, informing the type of correction to which the expression refers.

In strictly exceptional cases, an addendum will be published when there is a need to add relevant information to an already published article, without correcting the text, data, or digital assets. The addendum does not contradict the original content nor is it intended to correct errors, being used exclusively when the inclusion of the additional information significantly contributes to the understanding of the scientific contribution presented.

The publication of addenda may be subject to peer review, as determined by the editorial board of Educação Matemática Debate. All addenda will be linked to the article to which they refer, without the added information being directly incorporated into the original document. This procedure aims to preserve the original record of the publication while informing the academic community about relevant additions.

When the additional information impacts metadata, DOI, indexing, or bibliometric indicators, the publication of an addendum will not be permitted. In these cases, the information will be incorporated into the original article through the publication of an erratum.

Erratum will be published when necessary to correct errors or omissions that may influence the interpretation of the article, without compromising its overall academic integrity or invalidating the results or conclusions of the research or essay.

Whenever possible, the correction text will be prepared and approved by all authors of the article. In exceptional situations, when the error arises from the editorial process, the editors may publish the erratum without the direct participation of the authors, undertaking, however, to notify them beforehand.

Erratum requests may be subject to in-depth editorial review, and the editors may request additional information from the authors before approving the correction.

Educação Matemática Debate distinguishes between serious and minor errors. Serious errors are those that affect the interpretation of the article, even if they do not compromise its scientific integrity. Minor errors are those that do not interfere with the understanding, reliability, or interpretation of the text.

Serious errors will always be accompanied by the publication of a formal errata notice, which must:

• provide a clear description of the identified error and the changes made;
• be electronically linked to the corrected version of the article;
• be published as an independent document with its own pagination;
• be openly accessible to the public;
• be indicated on the title page of the corrected article via an electronic link.

Errata will not be published in the following cases:

• layout errors that do not imply the suppression of information;
• adjustments to typographic formatting — italics, bold, etc.;
• spelling errors that do not alter the meaning of the text, except for bibliographic data;
• corrections to authorship metadata.

There are three types of errata:

Information correction — used to correct texts, tables, figures, or other elements inserted incorrectly, honestly, without legal implications and without impact on the scientific validity of the research or essay.

Exclusion of information — refers to the removal of sections, tables, or figures due to an honest error, without compromising the results or scientific integrity.

Inclusion of information — when the additional information does not require direct modification of the original article, it should be published as an addendum.

A expression of concern may be published when there is significant evidence of serious problems related to the integrity of the research or publication, especially when the investigation is ongoing, inconclusive, or cannot be completed within a reasonable timeframe due to institutional or procedural circumstances.

The expression of concern is informative and preventative in nature, used to alert the academic community while the necessary investigations are underway.

This type of notice will be considered, among other situations, when:

• there is inconclusive evidence of possible misconduct;
• there are well-founded doubts about the reliability of the conclusions;
• institutional cooperation for research is limited;
• the research is ongoing with no expected completion date;
• the nature of the concerns justifies immediate communication to the academic community.

The expression of concern will remain linked to the published article and will permanently form part of the publication record, even after any correction or retraction is issued.

A retraction will be published when serious errors or evidence of scientific misconduct compromise the validity, reliability, or integrity of the article's conclusions.

The decision to retract will be made by the editors of Educação Matemática Debate after a detailed investigation. Authors, researchers, readers, or institutions may request a retraction, provided they present well-founded justifications.

The purpose of a retraction is to correct the academic record and should not be interpreted as a punitive sanction. Two types of retraction are foreseen:

• Total retraction — invalidates the entire content of the article;
• Partial retraction — invalidates a specific part of the published content.

Retraction may be applied, among other situations, when there is:

• fabrication, falsification, or manipulation of data;
• plagiarism, self-plagiarism, or redundant publication;
• compromised peer review;
• violation of ethical principles;
• relevant undeclared conflicts of interest;
• misuse of copyrighted materials;
• refusal by the authors to correct proven errors.

In cases of retraction, the editorial team will proceed to:

• publish a formal expression entitled Retraction: [article title];
• keep the article available with a watermark indicating Retracted;
• make the retraction available with its own pagination in the online edition.

The removal of an article is an exceptional measure and will only be adopted when the identified problems cannot be resolved through an erratum or retraction.

The editorial team of Educação Matemática Debate may remove an article when:

• there is a significant risk of harm arising from the content;
• there is a serious violation of privacy;
• there is a threat to the safety of people involved;
• there is defamatory or illegal content;
• there is a court order.

In cases of removal, the article's metadata will be preserved, and the full text will be replaced by a formal notice informing the legal reasons for the removal.
