Peer Review Process

Articles sent to Indomath will pass two stages of review, namely pre-review and substance review. Article pre-review was carried out by the editor to see the suitability of the article with the focus and scope of the journal as well as the style of confinement. An examination of the element of plagiarism is done through a search on Google Scholar, Plagiarism Checker-X Pro, Turnitin or Ithenticate. The duration of the pre-review is between 1-2 weeks. At least two reviewers conducted substance review in a single-blind manner. The duration of the review is between 4-5 weeks. If desired, the reviewer can request a review after the author has revised the article.

Decisions for publication, amendments or rejections are base on reviewers' reports or recommendations. There are four types of editor decisions based on reviewers' recommendations, namely:

  1. Accept Submission: Submissions will be accepted without revision.
  2. Revisions Required: Submissions will be accepted after a small change has been made. Articles sent back to the author for revisions must be returned to the editor without delay. Revised articles returned more than 20 days will be considered as new shipments. Revised articles can be sent to the editorial via the Online Submission Interface.
  3. Resubmit for Review: Submission must be reworked, but with significant changes, it can be accepted. Will need a second round review.
  4. Decline Submission: Submissions will not be published in the journal.

Publication Ethics and Malpractice Statement

Indomath: Indonesia Mathematics Education is a peer-reviewed electronic journal. This statement clarifies ethical behaviour of all parties involved in the act of publishing an article in this journal, including the author, the chief editor, the Editorial Board, the peer-reviewer and the publisher (Universitas Sarjanawiyata Tamansiswa). This statement is based on COPE's Best Practice Guidelines for Journal Editors.

Ethical Guideline for Journal Publication

The publication of an article in a peer-reviewed Indomath: Indonesia Mathematics Education is an essential building block in the development of a coherent and respected network of knowledge. It is a direct reflection of the quality of the work of the authors and the institutions that support them. Peer-reviewed articles support and embody the scientific method. It is therefore important to agree upon standards of expected ethical behavior for all parties involved in the act of publishing: the author, the journal editor, the peer reviewer, the publisher and the society.

Universitas Sarjanawiyata Tamansiswa as publisher of Indomath: Indonesia Mathematics Education takes its duties of guardianship over all stages of publishing extremely seriously and we recognize our ethical and other responsibilities. We are committed to ensuring that advertising, reprint or other commercial revenue has no impact or influence on editorial decisions. In addition, the Department of Mathematics Education of Universitas Sarjanawiyata Tamansiswa and Editorial Board will assist in communications with other journals and/or publishers where this is useful and necessary.

Publication decisions

The editor of the Indomath: Indonesia Mathematics Education is responsible for deciding which of the articles submitted to the journal should be published. The validation of the work in question and its importance to researchers and readers must always drive such decisions. The editors may be guided by the policies of the journal's editorial board and constrained by such legal requirements as shall then be in force regarding libel, copyright infringement and plagiarism.

Acknowledgement of Sources

Reviewers should identify relevant published work that has not been cited by the authors. Any statement that an observation, derivation, or argument had been previously reported should be accompanied by the relevant citation. A reviewer should also call to the editor's attention any substantial similarity or overlap between the manuscript under consideration and any other published paper of which they have personal knowledge.

Reviewers should not consider manuscripts in which they have conflicts of interest resulting from competitive, collaborative, or other relationships or connections with any of the authors, companies, or institutions connected to the papers.

Duties of Authors

Reporting standards

Authors of reports of original research should present an accurate account of the work performed as well as an objective discussion of its significance. Underlying data should be represented accurately in the paper. A paper should contain sufficient detail and references to permit others to replicate the work. Fraudulent or knowingly inaccurate statements constitute unethical behaviour and are unacceptable.

Data Access and Retention

Authors are asked to provide the raw data in connection with a paper for editorial review, and should be prepared to provide public access to such data (consistent with the ALPSP-STM Statement on Data and Databases), if practicable, and should in any event be prepared to retain such data for a reasonable time after publication.

Originality and Plagiarism

The authors should ensure that they have written entirely original works, and if the authors have used the work and/or words of others that this has been appropriately cited or quoted.

Multiple, Redundant or Concurrent Publication

An author should not in general publish manuscripts describing essentially the same research in more than one journal or primary publication. Submitting the same manuscript to more than one journal concurrently constitutes unethical publishing behaviour and is unacceptable.

Acknowledgement of Sources

Proper acknowledgment of the work of others must always be given. Authors should cite publications that have been influential in determining the nature of the reported work.

Authorship of the Paper

Authorship should be limited to those who have made a significant contribution to the conception, design, execution, or interpretation of the reported study. All those who have made significant contributions should be listed as co-authors. Where there are others who have participated in certain substantive aspects of the research project, they should be acknowledged or listed as contributors. The corresponding author should ensure that all appropriate co-authors and no inappropriate co-authors are included on the paper, and that all co-authors have seen and approved the final version of the paper and have agreed to its submission for publication.

Hazards and Human or Animal Subjects
