In-Text Citations

In APA style, in-text citations are used to acknowledge the source of a quote, idea, or piece of information within the text. The citation typically includes the author’s last name and the year of publication, separated by a comma. For example, (Smith, 2020) or (Johnson et al., 2019). If the source has no author, the title is used in the in-text citation, and the year of publication is included if available.
Citing Books
When citing books in APA style, the reference list entry typically includes the author’s last name, first initial, publication year, title of the book, and publisher. For example:
| Reference List Entry | Example |
|---|---|
| Book with one author | Smith, J. (2020). The psychology of learning. New York, NY: Routledge. |
| Book with multiple authors | Johnson, K., Williams, P., & Davis, J. (2019). Education and society. Thousand Oaks, CA: Sage Publications. |

Citing Articles
For articles, the reference list entry includes the author’s last name, first initial, publication year, title of the article, title of the journal, volume number, issue number, and page numbers. For example:
| Reference List Entry | Example |

| Journal article with one author | Smith, J. (2020). The impact of technology on education. Journal of Educational Psychology, 112(3), 456-463. |
| Journal article with multiple authors | Johnson, K., Williams, P., & Davis, J. (2019). Teacher perceptions of classroom technology. Journal of Teacher Education, 70(2), 147-155. |
Reference List Entries

A reference list is a list of all the sources cited in the paper, formatted according to APA style guidelines. Each reference list entry includes the author’s last name, first initial, publication year, title of the source, and publication information. The reference list is typically arranged alphabetically by author’s last name.
Citing Websites
When citing websites in APA style, the reference list entry typically includes the author’s last name, first initial, publication year, title of the webpage, title of the website, and the URL. For example:
| Reference List Entry | Example |

| Website with one author | Smith, J. (2020). The future of education. Retrieved from https://www.example.com |
| Website with no author | The impact of technology on education. (2020). Retrieved from https://www.example.com |
Formatting Guidelines
APA style has specific guidelines for formatting papers, including font, margins, and spacing. The recommended font is 12-point Times New Roman, with one-inch margins on all sides and double spacing throughout the paper. The title page includes the title of the paper, the author’s name, and the institutional affiliation.
