Understanding the Purpose of a Literature Review
A literature review is more than just a summary of existing research; it is a critical evaluation and synthesis of the available literature on your topic. It helps you:
- Identify the key theories, concepts, and research methodologies in your field.
- Discover gaps in the existing research that your study can address.
- Provide a context for your research question or hypothesis.
- Establish the relevance and importance of your study.
- Demonstrate your understanding of the scholarly conversation surrounding your topic.
Selecting and Evaluating Sources
The literature review process involves a careful selection and evaluation of sources. Here’s how to approach this:
Start Broad, Narrow Down: Begin by searching for general keywords related to your topic. As you read through abstracts and summaries, you’ll start to identify specific concepts, theories, and authors that are relevant to your research question.
Use Academic Databases: Academic databases like PsycINFO, JSTOR, and Google Scholar are invaluable for finding peer-reviewed articles and books. These sources offer a more reliable foundation for your literature review compared to general web searches.
Evaluate Source Quality: Not all sources are created equal. When selecting articles and books, consider the following:
- Relevance: Does the source directly address your research question or topic?
- Authority: Is the author an expert in the field? Are they affiliated with a reputable institution?
- Currency: For topics that evolve rapidly, more recent sources are often more valuable.
- Scope: Does the source provide a comprehensive or narrow perspective on the topic?
Diversify Your Sources: Aim for a mix of primary research articles, review articles, and books. This diversity will provide a more holistic view of the topic.
Organizing Your Literature Review
Once you’ve gathered a substantial collection of sources, it’s time to organize them into a coherent review. Here are some strategies:
Chronological Order: Arrange your sources in chronological order, especially if you’re tracing the evolution of a concept or theory. This approach can highlight how ideas have developed over time.
Thematic Organization: Group sources based on common themes, theories, or methodologies. This method is particularly useful when you want to compare and contrast different approaches or perspectives on a topic.
Critical Synthesis: Go beyond mere summarization by integrating your critical analysis. Discuss the strengths and limitations of each source, identify commonalities and discrepancies, and provide your own insights.
Writing Your Literature Review
The literature review section of your APA paper should be structured as follows:
Introduction: Begin with a brief overview of your topic and its significance. Introduce your research question and provide a roadmap for your review.
Body: This is where you present and analyze your sources. Use clear headings or subheadings to guide readers through the different themes or aspects of your review. Ensure each paragraph focuses on a specific point, backed up by evidence from your sources.
Conclusion: Summarize the key findings of your literature review. Highlight the gaps in existing research that your study aims to address, and conclude with a statement that transitions smoothly into the methodology section of your paper.
APA Formatting and Citation Guidelines
APA style provides specific guidelines for formatting and citing sources. Here are some key points to keep in mind:
Margins and Spacing: Use 1-inch margins on all sides and double-space your text.
Font and Size: Use a legible font like Times New Roman or Arial, and set the font size to 12 points.
Running Head and Page Numbers: Include a running head (a shortened version of your paper’s title) in the header of every page, flush left. Page numbers should be flush right.
Citations: APA uses the author-date citation style. In-text citations should include the author’s last name and the year of publication. For example: “(Smith, 2023)”.
Reference List: All sources cited in your literature review should be included in the reference list at the end of your paper. This list should be formatted alphabetically by the author’s last name.
Tips for Effective Literature Reviews
Stay Organized: Keep detailed notes on each source, including the key points, arguments, and evidence presented. This will make it easier to integrate sources into your review.
Avoid Plagiarism: Always use quotation marks for direct quotes and provide proper citations. Paraphrasing should also be done carefully to avoid unintentional plagiarism.
Engage with the Literature: Don’t simply summarize sources; critically engage with them. Discuss the implications of the research, its limitations, and how it contributes to your understanding of the topic.
Be Selective: Not every source you find will be equally valuable. Focus on the most relevant and influential works, and use them to build a comprehensive understanding of your topic.
Use Quotations Sparingly: Quotations should be used judiciously and only when the original wording is particularly powerful or unique. Overusing quotations can disrupt the flow of your review.
Future Implications and Conclusion
The literature review is an essential foundation for your research, helping you contextualize your study within the broader academic conversation. By understanding the existing literature, you can contribute to the scholarly discourse in a meaningful way.
As you continue your academic journey, remember that the literature review is a dynamic process. As you delve deeper into your topic, you may discover new sources, theories, and perspectives that enrich your understanding and shape your research direction.
