Submissions

Author Guidelines

We strongly recommend exploring this relevant content that should be taken into consideration:

The Journal accepts publication of:

1. Research Articles: original and unpublished works resulting from research efforts, with scientific or technical merit.
2. Review Articles: comprehensive bibliographic review, meta-analysis on a specific topic within the journal's fields of interest.

The journal only accepts articles in the Spanish language.

Manuscript submission is open on an ongoing basis.

Manuscripts must be original and exclusively submitted to Revista de Investigación Educativa Niveles for consideration during the evaluation process. Authors must register on the Open Journal System (OJS) platform of the journal and then submit their article following the corresponding links. In case of issues with manuscript submission, it can be sent to the email address revistaniveles@esprint.tech.

It is essential to consider and evaluate the received material by attaching the submission file in Microsoft Word format with the .docx extension (MS-Word Manuscript Template), along with the authors' information, databases, analyses, high-resolution article images (400 dpi) in a compressed folder (.rar or .zip), and any other material supporting the research conducted. This should be attached in the corresponding option that will appear in step 2 ("2. Upload Submission") during the article submission process.

Manuscript Format and Preparation

Citations and References must conform to Investigación Educativa Niveles guidelines (APA 7th Edition). Do not include references in the header or footer. We recommend referring to previous articles on our website and the following APA information available here.

Page, Font, and Text Size

Page size should be A4, with 2.5 cm margins on all sides, Times New Roman font, Size: 12 points, justified text, and 1.5 line spacing. Documents should have page numbers and be between 10 and 20 pages in length. It is suggested to use this MS-Word Manuscript Template.

Additional Guidelines

The title, abstract, and keywords must be presented in English. Author names should be listed below the title with the first name and last name, separated by commas, sequentially numbered in superscript to their affiliation. The sections "Conflict of Interest," "Acknowledgments," and "References" are not numbered.

Figures and Tables

Figure and table titles should follow the format "Figure #: description of the figure, Table #: description of the table" respectively. They should appear in the body of the text with sequential numbers according to their order of appearance. For tables, use only the bottom border to separate the titles and in the last row.

Equations, Symbols, and Units

Equations can be written in two ways: inline with the text or displayed equations:

1. Inline Equations:
   When equations are short and simple, such as x = [(7+y)/z)]½, they can be written in the same line as the text. It's important to note that equations written inline should stay strictly in line. Otherwise, the guidelines for displayed equations should be followed.
   
   The forward slash (/) is recommended to represent division when writing equations inline. Parentheses, brackets, and braces should be used in this order to avoid ambiguity: first ( ), then [ ], and finally { }.
2. Displayed Equations:
   Displayed equations should be used when an equation is difficult to understand in inline format or when it needs to be referenced later without rewriting it. In this case, equations should be consecutively numbered, with the equation number in parentheses near the right margin of the page.

Appendices

• An appendix is appropriate for relatively short materials that are easily presented in printed format.
• If a document has an appendix, label it as "Appendix";
• If a document has more than one appendix, label each appendix with an uppercase letter (e.g., "Appendix A," "Appendix B") in the order mentioned in the text.
• Start each appendix on a separate page after the References, Endnotes, Tables, and Figures.
• An appendix can consist of text, tables, figures, or a combination of these.

Manuscript Organization:

Revista de Investigación Educativa Niveles recommends the following article structure, which can be slightly modified if justified. Authors should provide comments to the editor regarding any changes to this structure.

1. Title. Should clearly identify the topic, written in bold, centered, with the first letter in uppercase. It should not exceed 18 words.
2. Author(s). Should be centered, in bold, and separated by commas. To avoid confusion in databases and citation loss, use full first name (without initials) and one last name for each author. If an author has two last names, use only the first one or use a hyphen. E.g., Juan Romero, María López-Romero.
3. Affiliations. Should follow the authors, indicating the institution (without abbreviations), Institution Name, Faculty (optional), Department (optional), City, Country, postal code. The corresponding author should be marked with an asterisk (*) and an email address. Do not modify author(s) and/or affiliations once the manuscript is registered in the Online System.
4. Abstract. Should be a single paragraph, not exceeding 250 words, containing five parts: (1) an introductory sentence indicating the topic's importance or problem, (2) the main objective of the manuscript, (3) a general description of the methods, treatments, or evaluations, (4) the main results expressed with values and statistical significance (P-value), and (5) the conclusion of the evaluation or analysis of experimental results. Do not cite figures, tables, or references; avoid equations.
5. Keywords. Write 5 keywords, separated by commas and in alphabetical order, obtained from the UNESCO Thesaurus. Some of them should also appear in the title and should be generalized descriptors of the study topic.
6. Introduction. Should contain specific background and justification of the topic, presented clearly and orderly, supported by appropriate and recent references (5 years or less, except for classic citations). The objective and hypothesis should be at the end of this section.
7. Methodology. Should provide enough information for the experiment to be reproducible, clearly defining the experimental design with specific descriptions or references for biological, analytical, and statistical procedures. Field experiments sensitive to interactions and where the cultivation environment cannot be rigorously controlled, such as production trials or yield components, must be repeated over time and/or space to ensure representative results.
8. Results. Should be clear and concise, supported by tables, figures (at the end of the article), and statistical analysis. Results should be discussed in the text without repeating values from tables and figures. Data should be presented including a measure of variability and/or statistical significance for the reader to interpret experimental results.
9. Discussion. Should interpret and compare results with similar studies, highlighting advantages and contributions. Analyze novel aspects while avoiding overpraising. Discuss each result separately and in order. State if the results are novel. Should answer: What is the significance of the obtained results and what do my findings mean? Start and finish with the main finding. (Optional section)

   Note: Major findings can also be discussed in the Results section if the author deems it appropriate.

10. Conclusions. Should address the objectives, start with a clear statement based on the results, supporting or rejecting the study's hypothesis. If the results have no implications, that should also be mentioned. Conclusions should be based on objective data and not on author speculations, should not go beyond the obtained results, and should not suggest further research. Do not use abbreviations, acronyms, or references.
11. Conflict of Interest. In this section, authors must declare that there are no conflicts of interest of any nature, or alternatively, declare the type of conflict of interest that the author(s) may have with this research.
12. Funding Source. Specify the funding source for the research; if the authors fully funded the research, also specify that.
13. Authorship Contribution Based on CRediT (adapted to the language of the journal). To ensure proper recognition of each author's contributions to the manuscript, a detailed breakdown of authorship contributions according to the CRediT (Contributor Role Taxonomy) must be provided. Please ensure to identify each author's contributions in the following CRediT categories:
    • Conceptualization: Ideas, formulation, or evolution of the general objectives and goals of the research.
    • Methodology: Development or design of the methodology; creation of models.
    • Software: Programming and software development; computer program design; implementation of support code and algorithms; testing of existing components. The advanced use of tools, such as customization, automation, or extension of functions in specialized software (e.g., reference management or data analysis tools), can also be considered under this category.
    • Validation: Verification, either as part of the activity or separately, of the overall replication/reproducibility of results/experiments and other research outcomes.
    • Formal Analysis: Application of statistical, mathematical, computational, or other formal techniques to analyze or synthesize study data.
    • Investigation: Conducting a research process, specifically performing experiments or collecting data/evidence.
    • Data Curation: Management activities to annotate (produce metadata), clean, and maintain research data (including software code, where necessary to interpret the data) for initial use and subsequent reuse.
    • Visualization: Preparation, creation, and/or presentation of the published work, specifically the visualization/presentation of data.
    • Writing - Original Draft Preparation: Preparation, creation, and/or presentation of the published work, specifically the writing of the initial draft (including substantive translation).
    • Writing - Review & Editing: Preparation, creation, and/or presentation of the published work by the original research group, specifically critical review, commentary, or revision, including pre- or post-publication stages.
    • Funding Acquisition: Securing financial support for the project leading to this publication. This category also includes cases where the author themselves covered their project costs.
    • Project Administration: Management and coordination responsibility for the planning and execution of the research activity.
    • Resources: Provision of study materials, reagents, materials, patients, laboratory samples, animals, instruments, computational resources, or other analysis tools.
    • Supervision: Responsibility for supervision and leadership in the planning and execution of the research activity, including mentorship external to the core team.
14. Acknowledgments. (Optional section).
15. References. Include recently published articles (less than 5 years), except for classic citations. Whenever possible, add a permanent link or DOI to the reference. The list of references should have 1.5 line spacing and hanging indentation. The list should be organized in alphabetical order by authors' last names.
16. Figures. Titles should be clear and self-explanatory.
