Understanding the Literature Review

What is a Literature Review?

The purpose of a literature review goes beyond summarizing existing research. It involves critically analyzing the current understanding of a specific topic. Ultimately, the review should present a narrative that not only summarizes existing knowledge but also uncovers any gaps, trends, and the significance of previous studies to one's own research.

Why is it Important?

Consider the literature review to be the cornerstone of your Dissertation. It demonstrates your grasp of the field and lays the groundwork for your research. A carefully constructed review has the potential to greatly enhance your Dissertation by placing your research questions within the framework of existing knowledge. When gathering data or literature, it is important to rely on trustworthy sources to uphold credibility. Relying on unreliable sources like blogs and untrustworthy websites could undermine the integrity of your literature.

 

Steps to Writing a Literature Review

1. Define Your Research Question

Prior to beginning your literature review, it's important to have a well-defined research question. This question will drive your search for pertinent literature and keep you on track. A clear question serves as a guide, shaping your review and ensuring it stays connected to your Dissertation.

Conduct a Comprehensive Literature Search

It's important to conduct a comprehensive search. Make sure to make use of academic databases like JSTOR, Google Scholar, and PubMed. When you're conducting your search, be sure to use precise keywords and phrases that relate to your topic. Avoid relying solely on the initial sources you come across; it's important to explore different databases in order to gather a wide variety of materials.

Using Academic Database

Various databases provide access to varying types of resources. JSTOR, for example, offers access to journals, whereas Google Scholar encompasses a wider range of academic literature. Adjust your search strategy based on the databases you are using.

Searching for Relevant Sources

Consider looking beyond the most apparent sources. This includes incorporating peer-reviewed articles, books, and trustworthy reports. Make sure to gather varied perspectives to enhance your review.

Evaluate and Select Sources

Evaluate the credibility and relevance of each source because not all sources are equal.

Assessing Credibility

Ensure that you verify the author's credentials and consider the reputation of the publication. Generally, information from peer-reviewed journals is more dependable compared to non-reviewed sources.

Relevance to Your Topic

Make sure that every source is directly connected to your research question. Sources that are not relevant can lower the quality of your review.

Organize the Literature

Once you’ve selected your sources, organize them effectively.

Thematic Organization

Group studies by themes or topics. This approach allows you to discuss different aspects of the literature systematically.

Chronological Organization

Alternatively, organize sources chronologically to show the evolution of the research over time.

Write the Literature Review

Now it’s time to write. Your review should summarize, synthesize, and critique the sources you’ve gathered.

Summarize and Synthesize

Present the main findings of each study and integrate them to highlight trends or gaps in the literature.

Analyze and Critique

Don’t just summarize. Analyze the strengths and weaknesses of each study and critique the methodologies and findings.

Common Pitfalls to Avoid

Overloading with Information

It’s tempting to include everything you’ve read, but be selective. Too much information can overwhelm your readers and obscure your main points.

Tone and Voice

Tailor your tone to suit your audience and the purpose of your writing. When writing academic essays, keep a formal and objective tone. On the other hand, consider using a more conversational voice for a personal narrative. Ensure that your tone remains consistent throughout the entire essay.

Ignoring Key Studies

Be mindful not to overlook significant studies. Missing key research can undermine the credibility of your review.

 

 

Final Tips for a Strong Literature Review

Maintain a Clear Focus

Stay on topic. Every section of your review should relate back to your research question.

Ensure Coherence and Flow

Your review should read like a cohesive narrative. Use transitions to connect sections and maintain a logical flow.

 

Conclusion

Creating a comprehensive literature review goes beyond simply recapping previous studies. It entails conducting a thorough analysis, thoughtfully choosing relevant sources, and establishing a coherent structure. Adhering to these guidelines will enable you to build a strong groundwork for your Dissertation, showcasing your grasp of the subject matter and laying the groundwork for your own research advancements.

 

FAQs

The length varies based on your Dissertation requirements and the complexity of your topic, but typically, it should be around 15-30% of your Dissertation length.

While academic sources are preferred, relevant non-academic sources can be included if they contribute valuable perspectives.

Check the author’s credentials, the publication’s reputation, and whether the source has been peer-reviewed.

Summarizing presents the main points of a study, while synthesizing integrates findings from various studies to show trends and gaps.

Update your review periodically to include recent research, especially if there’s a significant gap between your initial review and your final Dissertation.
