The results of mathematics education studies will have a comprehensive and strategic impact on the development of science and society at large. Therefore, every manuscript that is submitted to POSTULAT's editorial staff must go through a “Peer Review” process before being declared accepted and published. In this case the reviewers have a very important role in maintaining the quality of the articles published.

At the first stage, The submitted manuscript is reviewed by an editor except for invited manuscript. It will be evaluated wether the manuscript suitable for journal template, focus and scope. The editor will run a plagiarism check using Plagiarism Checker for the submitted articles before sending it to the reviewers. We do not process any plagiarised contents. If an article has over 15% of plagiarism based on the result of the check, we will send back the article to the author to be revised for the plagiarised contents. The journal is carried out by using Mendeley as a Tool Reference Manager. The language used in this journal is English.

From the editor, the manuscript will be sent to at least two anonymous referees (double-blind review) for contribution, originality, relevance, and presentation. Reviewers' comments are then sent to the corresponding author for necessary actions and responses. The Editor shall inform you of the results of the review as soon as possible, hopefully in 30 to 60 days.

The accepted research articles will be available online (free download) following the journal peer-reviewing process. The final decision of articles acceptance will be made by Editors according to Reviewers' comments. The articles sent back to the authors for revision should be returned not more than 30 days. The revised article can be sent to the editorial through the Online Submission Interface. The revised article returned after 30 days will be considered as new submissions.

All articles published Open Access will be immediately and permanently free for everyone to read and download.
