 The International Journal of Didactic Mathematics in Distance Education (IJDMDE) is a fully open-access, peer-reviewed academic journal. The journal is committed to the widest possible dissemination of scholarly knowledge in the field of mathematics education in distance and blended learning environments. To fulfil this commitment, IJDMDE operates under a clear and transparent copyright and licensing framework that protects the rights of authors while ensuring that published research remains freely accessible to readers, researchers, educators, and institutions worldwide.

This policy sets out the rights and obligations of authors, the journal, and users of published content, and is designed to be fully compliant with the requirements of Scopus, the Directory of Open Access Journals (DOAJ), the Budapest Open Access Initiative (BOAI), and the Creative Commons licensing framework.

1. Open Access Statement

IJDMDE is published as a fully open-access journal. This means that all articles are freely available online immediately upon publication, without any subscription fee, paywall, or embargo period. Readers are permitted to read, download, copy, distribute, print, search, and link to the full text of all articles without requiring prior permission from the publisher or author, provided that the original work is properly attributed.

 IJDMDE's open-access model is consistent with the principles of the Budapest Open Access Initiative (BOAI, 2002) and the Berlin Declaration on Open Access to Knowledge in the Sciences and Humanities (2003). The journal does not charge readers or their institutions for access to any published content.

Open Access Definition (BOAI): "By 'open access' to this literature, we mean its free availability on the public internet, permitting any users to read, download, copy, distribute, print, search, or link to the full texts of these articles, crawl them for indexing, pass them as data to software, or use them for any other lawful purpose, without financial, legal, or technical barriers other than those inseparable from gaining access to the internet itself." — Budapest Open Access Initiative, 2002

2. Copyright Ownership and Retention

IJDMDE respects and upholds the intellectual property rights of authors. The journal's copyright policy is structured to balance the journal's need to publish and disseminate work with the authors' legitimate interest in retaining ownership of their creative and intellectual output.

 2.1 Authors Retain Copyright

Authors who publish in IJDMDE retain the copyright to their work. Upon submission and acceptance of a manuscript for publication, authors are not required to transfer copyright ownership to the journal or the publisher. Instead, authors grant IJDMDE a non-exclusive licence to publish the work, as described in Section 3 below.

This author-retentive copyright model means that:

  • The author(s) remain(s) the legal copyright holder(s) of the published article at all times
  • Authors may reuse their own work freely, including in subsequent publications, books, theses, or presentations, provided that the original publication in IJDMDE is properly acknowledged
  • Authors do not need to seek permission from the journal to reuse or reproduce their own published work
  • Copyright is held jointly by all listed authors in the case of multi-author manuscripts, unless otherwise agreed in writing among the authors

 2.2 Copyright Notice

All articles published in IJDMDE carry the following copyright notice, which must be preserved in any reproduction or distribution of the work:

 

Standard Copyright Notice: © [Year of Publication] [Author Name(s)]. Published by the International Journal of Didactic Mathematics in Distance Education (IJDMDE). This is an open-access article distributed under the terms of the Creative Commons Attribution-ShareAlike 4.0 International License (CC BY-SA 4.0), which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited and any derivative works are distributed under the same license.

 2.3 Licence Grant to the Journal

By submitting a manuscript to IJDMDE and agreeing to these terms upon acceptance, author(s) grant the journal a perpetual, worldwide, non-exclusive, royalty-free licence to:

  • Publish, reproduce, and distribute the article in print and electronic formats
  • Archive and preserve the article in digital repositories
  • Translate and adapt the article for purposes of accessibility and indexing
  • Sublicense the article to indexing services, repositories, and aggregators (including Scopus, Google Scholar, DOAJ, and others) under the terms of the CC BY-SA 4.0 licence

This licence grant does not affect the author's ownership of copyright, which is retained in full.

 2.4 First Publication Rights

Authors grant IJDMDE first publication rights, meaning that IJDMDE has the right to be acknowledged as the venue of first publication of the work. When authors subsequently republish or redistribute their work in any other form or venue, they are required to include a clear acknowledgment that the work was originally published in IJDMDE, with a full citation and a link to the original article (e.g., via DOI).

 3. Creative Commons CC BY-SA 4.0 Licence

All content published in IJDMDE is licensed under the Creative Commons Attribution-ShareAlike 4.0 International License (CC BY-SA 4.0). This licence is one of the most widely used and recognised open-content licences internationally and is accepted by major indexing databases, funding bodies, and academic institutions worldwide.

 3.1 What the CC BY-SA 4.0 Licence Permits

Under the CC BY-SA 4.0 licence, any person — whether an individual researcher, educator, institution, or commercial entity — is permitted to:

Right Description Condition
Share Copy and redistribute the article in any medium or format, including print, digital, audio, and visual formats Must give appropriate attribution (see Section 3.2)
Adapt Remix, transform, and build upon the article for any purpose, including commercially Derivative works must carry the same CC BY-SA 4.0 licence
Commercial Use Use the article and any adaptations for commercial purposes without seeking additional permission Attribution and ShareAlike conditions must be met
Translate Translate the article into other languages and distribute the translation Attribution required; translated version must carry CC BY-SA 4.0
Incorporate Incorporate the article, in whole or in part, into other works, datasets, or teaching materials The resulting work must be distributed under CC BY-SA 4.0

 3.2 Attribution Requirements (BY)

The Attribution (BY) component of the licence requires that anyone who uses, shares, or adapts content published in IJDMDE must provide attribution that is appropriate to the medium, means, and context. Specifically, users must:

  1. Identify the original author(s) by name as they appear on the published article
  2. Provide the full title of the article as published
  3. Identify IJDMDE as the journal of publication
  4. Provide the year of publication
  5. Include the DOI (Digital Object Identifier) or the URL of the original article wherever technically possible
  6. Include a link to or a statement of the CC BY-SA 4.0 licence
  7. Indicate if any changes were made to the original work (e.g., translation, adaptation, abridgement)

Attribution does not imply that the original authors endorse the user's work, use, or the institution producing the derivative work.

 

Recommended Citation Format: Author Surname, Initial(s). (Year). Title of article. International Journal of Didactic Mathematics in Distance Education, Volume(Issue), Page range. https://doi.org/[DOI] Example: Rahmawati, S., & Putra, A. (2024). Scaffolding strategies in online mathematics learning: A systematic review. International Journal of Didactic Mathematics in Distance Education, 3(1), 1–18. https://doi.org/10.xxxxx/ijdmde.xxxxx

 3.3 ShareAlike Requirements (SA)

The ShareAlike (SA) component is a fundamental condition of the CC BY-SA 4.0 licence and serves to ensure that the culture of open access and free sharing is preserved across derivative works. This condition requires that:

  • Any work that is derived from, adapted from, or built upon an article published in IJDMDE — including translations, abridgements, compilations, or remixed works — must be distributed under the same CC BY-SA 4.0 licence, or a licence that is compatible with CC BY-SA 4.0 as defined by Creative Commons
  • The ShareAlike condition applies regardless of the medium, format, or platform through which the derivative work is distributed
  • Licensees may not apply additional legal restrictions or technological measures (such as digital rights management) to derivative works that would prevent others from exercising the rights granted by the CC BY-SA 4.0 licence
  • Derivative works must carry a clear and conspicuous notice that they are distributed under CC BY-SA 4.0, and must include or link to the full licence text.

The ShareAlike condition does not require that original, independently created works that merely reference or cite IJDMDE articles be distributed under CC BY-SA 4.0. The condition applies only to works that incorporate or adapt substantial portions of IJDMDE content.

 3.4 What the CC BY-SA 4.0 Licence Does NOT Permit

The CC BY-SA 4.0 licence does not override all rights. The following uses remain restricted and may require separate permission:

  • Misrepresenting the author(s) of the original work or implying endorsement by the original author(s)
  • Removing or obscuring the copyright notice, attribution information, or licence statement from the original article
  • Applying technological restrictions to the original article that prevent others from exercising rights granted by the CC BY-SA 4.0 licence
  • Using the content in a manner that violates applicable laws, including data protection, privacy, or defamation law
  • Using an author's name, likeness, or endorsement in a misleading or deceptive manner

 3.5 Licence Compatibility

The CC BY-SA 4.0 licence is compatible with several other open content licences, enabling content from IJDMDE to be combined with content from other open-access sources. The following table summarises compatibility:

Licence Compatible with CC BY-SA 4.0? Notes
CC BY 4.0 Yes (one direction) CC BY content can be incorporated into CC BY-SA works; not the reverse
CC BY-SA 4.0 Yes (fully) Fully compatible; same licence
CC BY-NC-SA 4.0 No Non-commercial restriction is incompatible with CC BY-SA
CC BY-ND 4.0 No No-derivatives restriction is incompatible with CC BY-SA
CC0 (Public Domain) Yes CC0 content can be incorporated freely into CC BY-SA works
All Rights Reserved No Proprietary content cannot be combined with CC BY-SA works

 4. Author Rights and Permitted Uses

In addition to retaining copyright, authors of articles published in IJDMDE retain the following specific rights and freedoms:

4.1 Preprint Posting

Authors are permitted and encouraged to post preprint versions of their manuscript (i.e., the author's original manuscript before peer review) on personal websites, institutional repositories, preprint servers (such as arXiv, SSRN, OSF Preprints, or EduArXiv), or collaborative platforms at any time before, during, or after the submission process. Posting preprints does not constitute prior publication and will not disqualify a manuscript from consideration in IJDMDE.

When posting a preprint, authors are encouraged — but not required — to include a statement indicating that the manuscript has been submitted to IJDMDE.

 4.2 Accepted Manuscript (Postprint) Posting

Following acceptance of the manuscript, authors may post the accepted version of the manuscript (the postprint — i.e., the peer-reviewed version before copyediting and typesetting) to:

  • Their personal or institutional website
  • Their institutional or subject-specific repository
  • Preprint servers or collaborative platforms

 When posting an accepted manuscript or postprint, the author must include the following statement and citation to ensure proper attribution to the journal of record:

Required Postprint Attribution Statement: "This is the accepted manuscript version of an article published in the International Journal of Didactic Mathematics in Distance Education (IJDMDE). The final published version is available at: [DOI or URL of the published article]. Published under CC BY-SA 4.0."

4.3 Published Version (Version of Record) Posting

Authors may also deposit, post, or share the final published version of record (the PDF or HTML as published on the IJDMDE website) in any repository, platform, or medium, since the CC BY-SA 4.0 licence grants this right to all users including the authors themselves. When doing so, the published DOI link must be included.

 4.4 Reuse in Teaching and Educational Materials

Authors may freely incorporate their published IJDMDE articles, in whole or in part, into:

  • Course syllabi, lecture slides, and teaching notes
  • Textbooks or edited book chapters (subject to the CC BY-SA 4.0 ShareAlike condition)
  • Student theses or dissertations
  • Grant applications and research reports
  • Conference presentations and proceedings

 In all such cases, a citation to the original IJDMDE article must be included. When articles or substantial portions are incorporated into other published works, the CC BY-SA 4.0 licence conditions (attribution and ShareAlike) must be observed.

 4.5 Translation Rights

Authors may arrange for the translation of their published IJDMDE articles into other languages and distribute the translated version, provided that the translated version carries the CC BY-SA 4.0 licence and a clear attribution statement linking back to the original English-language article in IJDMDE. Authors are encouraged to notify the Editorial Board when a translation is published, so that a link to the translation can be added to the article record where possible.

 5. User Rights and Permitted Uses

Any person or entity — including individual readers, researchers, educators, librarians, journalists, data scientists, commercial publishers, and non-profit organisations — is permitted to use content published in IJDMDE under the terms of the CC BY-SA 4.0 licence without seeking prior permission from the authors or the journal. The following table summarises the key permitted uses:

 6. Copyright Infringement and Complaint Procedure

IJDMDE is committed to protecting the intellectual property rights of all parties and to addressing copyright concerns promptly and in accordance with applicable law and COPE ethical guidelines.

 6.1 Grounds for a Copyright Complaint

A copyright complaint may be raised when a person believes that content published in IJDMDE:

  • Was taken from another source without proper attribution or permission (plagiarism)
  • Reproduces a substantial portion of a previously published copyrighted work without authorisation and without fair use or open-licence justification
  • Misattributes authorship or ownership of the work
  • Violates the ShareAlike condition of the CC BY-SA 4.0 licence by distributing a derivative work under incompatible terms

 6.2 How to Submit a Copyright Complaint

Any person who believes that content published in IJDMDE infringes their copyright, or the copyright of someone they are authorised to represent, must submit a formal written complaint to the Editorial Board. The complaint must include the following information:

  1. The complainant's full name, institutional affiliation (if applicable), and contact information
  2. A precise identification of the copyrighted work that is alleged to have been infringed (e.g., title, publication venue, DOI, year)
  3. A precise identification of the IJDMDE article alleged to contain the infringing content, including the title, authors, volume, issue, page numbers, and DOI
  4. A specific description of the material within the IJDMDE article that is alleged to be infringing, with page numbers or section references
  5. A statement of the basis for the complaint, including the complainant's rights in the allegedly infringed work
  6. A declaration that the information in the complaint is accurate and that the complainant is the copyright holder or is authorised to act on behalf of the copyright holder

 6.3 Complaint Processing

Upon receipt of a copyright complaint, the Editorial Board will:

  1. Acknowledge receipt of the complaint within five (5) business days
  2. Conduct a preliminary assessment of the complaint to determine whether it falls within the scope of this policy
  3. Forward the complaint to the corresponding author(s) of the article in question for their response
  4. Evaluate the complaint and the author's response in accordance with COPE guidelines on publication ethics
  5. Take appropriate corrective action if the complaint is upheld (see Section 8.4)
  6. Inform both the complainant and the author(s) of the outcome within a reasonable timeframe

6.4 Corrective Actions

If a copyright infringement complaint is upheld following investigation, IJDMDE may take one or more of the following corrective actions, proportionate to the nature and severity of the infringement:

  • Publishing a Correction (Erratum) notice if the infringement is minor and the article can be revised
  • Publishing an Expression of Concern if the investigation is ongoing or inconclusive
  • Publishing a formal Retraction notice if the infringement is substantial and the integrity of the article is fundamentally compromised
  • Adding a persistent notice to the online article record describing the copyright concern and its resolution
  • Notifying the author's affiliated institution in cases of deliberate or egregious infringement

 All corrective notices will be published as separate, citable documents permanently linked to the original article in accordance with COPE Retraction Guidelines.

 7. Moral Rights

Irrespective of the copyright and licensing framework described in this policy, authors of articles published in IJDMDE retain their moral rights in the work as recognised under applicable national and international law. These moral rights include, but are not limited to:

  • The right of attribution (paternity): the right to be identified as the author of the work
  • The right of integrity: the right to object to derogatory treatment of the work that would damage the author's honour or reputation
  • The right of disclosure: the right to decide when and how the work is first made available to the public (exercised upon submission and acceptance)

IJDMDE will not take any action that would infringe the moral rights of authors. Users of published content are similarly required to respect the moral rights of authors, including by ensuring that attribution is accurate and that any adaptation does not misrepresent the original authors' views or damage their reputation.

8. Warranties and Author Representations

By submitting a manuscript to IJDMDE and agreeing to these terms, each author individually and jointly represents and warrants to the journal that:

The submitted work is original and has not been published previously in any journal, book, or other publication, and is not under consideration for publication elsewhere at the time of submission

  1. The author(s) is/are the sole creator(s) of the work and possess(es) the full right and authority to grant the licences described in this policy
  2. The work does not infringe any existing copyright, trademark, patent, trade secret, or other intellectual property right of any third party
  3. Where the work incorporates text, data, images, or other content from third-party sources, appropriate permission has been obtained and attribution has been given
  4. All co-authors have been identified and have agreed to the submission, the authorship order, and the licensing terms of this policy
  5. All required ethical approvals, participant consents, and institutional permissions relevant to the research have been obtained
  6. The work complies with all applicable laws and regulations, including data protection and privacy law

 9. Third-Party Content and Permissions

Authors are responsible for obtaining all necessary permissions for the inclusion in their manuscripts of any third-party content — including text extracts, figures, tables, images, data, computer code, or other materials — that is protected by copyright and that is reproduced beyond the scope of fair use or fair dealing.

Where third-party content is included under permission, the nature of the permission and any associated licence conditions must be clearly stated in the article (typically in the figure caption, table note, or acknowledgments section). Any conditions imposed by the rights holder of the third-party content must be observed by all subsequent users of the IJDMDE article.

 

Authors should note that the CC BY-SA 4.0 licence that applies to IJDMDE articles applies only to the author's own original contribution; it does not override the copyright status of third-party content included within the article. If third-party content is included under a licence that is incompatible with CC BY-SA 4.0, this must be clearly indicated.

10. Compliance with Scopus and Indexing Requirements

IJDMDE's copyright and licensing policy is designed to meet and exceed the content integrity and open-access requirements of Scopus and other major indexing databases. The following elements of the policy are specifically relevant to Scopus compliance:
