Guideline for Author

Preparing Your Paper

Please refer to these quick style guidelines when preparing your paper, rather than any published articles or a sample copy.

1. Article title

  • Bold font. Only the first word in the article title is capitalized with size 16 left-align unless the word usually is capitalized; article title should be no longer than 20 words (exception condition).
  • The Journal welcomes the article submissions which attract the interest of a wide scholarly readership, convey clear and accurate information, and highlight novel issues or perspectives in academic research.
  • Refrain from the use of abbreviations and question words in the article title.


  • Problematising “student choice” in classrooms
  • Students’ historical contextualization and the cold war

2. Author names

  • Author names begin with “by” (italic), followed by the author’s name (italic - bold), and the author’s agency name enclosed in parentheses (italic).
  • Given name appears first, family and middle name appears last.
  • Articles with multiple authors must be in order showing their contributions (not based on academic title, degree, or position). The name of major contributors is placed first, followed by the name of less prominant contributors. A comma is placed to separate author names.

3. Abstract

  • There is an “ABSTRACT” heading (italic, note it is capitalized).
  • Abstract should be 150-250 words for both structured and unstructured forms.
  • A structured or unstructured abstract should be in order: background, methods, results, and conclusion.
  • The author must not use abbreviations in the article title.

4. Keywords

  • Note “Keywords:” as a heading (left-align note there is a terminal colon).
  • Keywords are in alphabetical order and separated by commas.
  • Up to 5 keywords are allowed.
  • There is no period after the last keyword.
  • Keywords are in lower case only (unless it is a proper noun, species name).

5. Main text

1) Section headings

  • Articles generally use these Level I headings in bold (exception condition) (Introduction, Literature Reviews, Methods, Results, Discussion, Acknowledgements, and References).
  • Depending on the article, there may be Level II headings (italic).
  • Depending on the articles, there may be Level III headings (italic) whereas Level II (bold italic).


Literature Reviews

Participants I
Participants II


  • Level I headings: bold font, with 1 line of space before it.
  • Level II headings and Level III headings: there is 0 line of space before them.

2) Paragraphs

  • First paragraph under any level of section heading is indented 1cm.
  • Subsequent paragraphs in the articles are indented 1cm.

3) Abbreviations

  • If a term/definition is continually mentioned, it is written in full when it first appears, followed by the subsequent abbreviation in parentheses (even if it was previously defined in the abstract); after that, the abbreviation is used.
  • Make sure that an abbreviation so defined does actually appear later in the text (excluding in tables/figures).
  • Please refer to the abbreviated conventions relating to the major in the article.

4) Terminology

  • Terminology of the paper should be used, except for some commercial terms, the common name of the issue directly related to the discussion.
  • The international scientific terminology should be adhered to.

5) Numbers

  • Numbers beginning a sentence or those < 10 (i.e one to nine) are shown in words.
  • Laboratory parameters, time, temperature, length, area, mass, and volume are represented in digits.
  • Centuries and decades are written out using digits, e.g. the 1990s or 20th century
  • Numbers within parentheses are expressed in digits even if < 10
  • A dot is used as a thousand separator, e.g. 1.980, or 6.470.880.

6) Statistics

  • Statistic APA style is used.
  • Use readable spacing, placing a space after commas, variables and mathematical symbols. For example:
    • r(55) = .49, p < .001 (correct)
    • r(55)=.49,p<.001. (incorrect)
  • Don’t state formulas for common statistics (e.g. variance, z-score).
  • Don’t use references for statistics unless they are uncommon or the focus of your study.
  • Don’t use a zero before a decimal point when the statistic cannot be greater than 1 (e.g. p = .015)
  • Place a zero before the decimal point if the statistic can be greater than 1 (e.g. 0.29 1b)
  • Symbols should be italicized: t, F, z (exception condition)
  • Place percentages in parentheses, e.g. Most of my students (90.5%) passed the final exam

7) Units

  • SI units should be used throughout unless it is common practice in the field to use other units.
  • Metric system is used for the expression of length, area, mass, and volume.
  • Take care to use the correct case for the units, e.g. write 20 km and not 20 Km
  • The journal uses “l” rather than “L” as the symbol for liters, e.g. 100ml
  • Temperatures are given in degree Celsius, e.g. 150C (no space between number and degree symbol).
  • Virgule (/) is used, e.g. 3 times/per day

8) Miscellaneous style points

  • There are two ways using “vs”: When within parentheses, use “vs.” (italic with end period), e.g. (boys vs. girls); when not in parentheses, spell it out (not italic), e.g. boy versus girls
  • When within parentheses, use “%”, e.g. (100% and 20%); when not within parentheses, spell it out, e.g. 100 percent, 20 percent
  • Italicize all foreign-language term, e.g. ad nauseam, bon voyage, bona fide, en masse, pro bono, ect.
  • Italicize species names, e.g. You would find spice mixes like gram masala, chole masala, rajma masala, nihari masala, 5-spice panch phoran spice mix etc.
  • “st”, “nd”, “rd”, “th” are not superscripted after numbers, e.g. 21st, 22nd, 23 rd (not 23rd, 1st )
  • Use en dashes () without space for number ranging, e.g. 2(1),12–24
  • Contraction do not have end period, e.g. Prof Châu, Ms Hoa (not Prof. or Ms.)
  • Quotes: double quotes are used; single quotes used for quotes within a quote
  • For equipment, software, chemical reagents, etc. should be provided in details, e.g. APA 6th edition, MLA 8th edition
  • Or if name of products is within parentheses: (APA 6th edition, MLA 8th edition)

9) Tables

  • Be consistent in the formatting and vocabulary of all tables when writing a paper
