Jurnal Didactical Mathematics is committed to maintaining high standards of publication ethics and academic integrity throughout the publication process. This publication ethics statement defines the responsibilities and ethical conduct expected of authors, editors, editorial board members, reviewers, and the publisher. The policy is based on established principles of responsible scholarly publishing and the Committee on Publication Ethics (COPE) guidelines.

General Principles

The publication of research in Jurnal Didactical Mathematics is intended to contribute to the advancement of knowledge in mathematics education. All parties involved in the publication process are expected to act with honesty, fairness, transparency, academic independence, confidentiality, and respect for the integrity of scholarly work.

Editorial decisions are based on scholarly considerations and are independent of commercial, institutional, personal, or other inappropriate influences. The journal does not tolerate fabrication, falsification, plagiarism, manipulation of citations, duplicate publication, or other forms of research and publication misconduct.

Editorial Responsibilities

Publication Decisions

The Editor-in-Chief and editors are responsible for making publication decisions based on the scholarly quality, originality, methodological rigor, relevance, and contribution of the manuscript. Editorial decisions are informed by peer review and journal policies and are not determined by commercial considerations, authors' institutional affiliation, nationality, gender, or other irrelevant characteristics.

Fair and Independent Evaluation

Editors must evaluate manuscripts fairly and consistently and must ensure that manuscripts are processed according to the journal's established editorial and peer review procedures.

Confidentiality

Editors and editorial staff must maintain the confidentiality of submitted manuscripts, reviewer identities, reviewer reports, author responses, and related editorial communications. Manuscript information must not be disclosed to unauthorized parties.

Conflicts of Interest

Editors must not participate in editorial decisions concerning manuscripts in which they have a personal, professional, financial, institutional, or other conflict of interest. Where appropriate, the manuscript must be assigned to another qualified editor.

Duties of Reviewers

Contribution to Editorial Decisions

Peer review assists editors in making informed editorial decisions and provides authors with constructive feedback that may improve the quality, clarity, and scholarly contribution of their work.

Expertise and Promptness

Reviewers should accept assignments only when they have appropriate expertise and sufficient time to conduct a careful and objective evaluation. Reviewers who cannot complete a review within the expected period should promptly inform the editor and decline the assignment when necessary.

Objectivity

Reviews must be objective, evidence-based, and professionally expressed. Personal criticism of authors is inappropriate, and comments should focus on the manuscript and its scholarly quality.

Confidentiality and Conflicts of Interest

Reviewers must treat all manuscripts as confidential documents and must not use unpublished information for personal or professional advantage. Reviewers must disclose any actual or potential conflict of interest and decline the assignment when such a conflict could compromise impartial evaluation.

Duties of Authors

Originality and Exclusive Submission

Authors must submit original work that has not been published previously and is not simultaneously under consideration by another journal. Authors must appropriately acknowledge and cite all sources used in the manuscript.

Accuracy and Research Integrity

Authors are responsible for the accuracy and integrity of the reported research. Data must not be fabricated, falsified, selectively manipulated, or intentionally misrepresented. Research methods, analytical procedures, and findings should be reported sufficiently to support scholarly evaluation.

Authorship

Authorship should be limited to individuals who have made substantial intellectual or scholarly contributions to the work. All listed authors must approve the final manuscript and agree to its submission and publication. Individuals who do not meet authorship criteria should be appropriately acknowledged rather than listed as authors.

Conflicts of Interest

Authors must disclose any financial, institutional, personal, or professional relationships that could reasonably be perceived as influencing the research or its interpretation.

Correction of Errors

Authors are expected to promptly notify the journal if they discover a significant error or inaccuracy in their published work and to cooperate with the editorial team in issuing a correction or other appropriate post-publication action.

Research Integrity and Ethical Approval

Research involving human participants, identifiable personal information, or other ethically sensitive materials must comply with applicable ethical standards and institutional requirements. Where ethical approval is required, authors should provide appropriate information regarding the approval and responsible institution. Authors are also responsible for protecting participant confidentiality and reporting research procedures honestly.

Plagiarism and Publication Misconduct

The journal does not tolerate plagiarism, substantial text recycling, duplicate or redundant publication, citation manipulation, fabricated or falsified data, authorship misconduct, or other forms of publication malpractice. Submitted manuscripts may be screened using plagiarism-detection software and may be subject to further editorial investigation when concerns arise.

Responsible Use of Artificial Intelligence

Authors remain fully responsible for the originality, accuracy, integrity, and scholarly content of their manuscripts when using artificial intelligence or other technology-assisted tools. Such tools must not be used to fabricate data, generate misleading references, manipulate results, or replace the authors' scholarly judgment. Reviewers must not upload confidential manuscript content to generative AI systems or use AI to replace their independent peer review. Any material use of AI-assisted tools should comply with the journal's applicable AI policy.

Corrections and Retractions

The journal may publish corrections, expressions of concern, retractions, or other appropriate notices when significant errors, ethical concerns, or publication misconduct are identified. Such actions are undertaken to preserve the integrity of the scholarly record.

Appeals and Complaints

Authors may appeal an editorial decision when they can provide substantive reasons that the decision resulted from a significant procedural or evaluative error. Appeals and complaints are considered by the editorial team in accordance with the journal's policies and principles of fairness, confidentiality, and editorial independence.

Publisher Responsibilities

The publisher and Editorial Board are committed to maintaining the integrity and independence of the publication process. Commercial activities, publication fees, advertising, or institutional interests must not influence editorial decisions. The journal will take reasonable steps to investigate suspected ethical violations and to correct the scholarly record when necessary.
