A Student's Guide to Finding and Evaluating Credible Sources
The basis of effective academic writing lies in thorough and credible research. The vast sea of online information makes it challenging to navigate the research process and locate credible sources. A systematic approach is necessary in finding and evaluating credible sources to gather reliable, accurate, and relevant information.
Developing a research question
The first step relevant to finding credible sources is to develop a strong research question. The question helps to:
- zero in on specific topics and keywords,
- avoid overly broad or irrelevant sources,
- identify relevant journals, publications, and databases with pertinent information.
A well-defined research question helps assess whether a source will contribute to answering the question. The researcher determines:
- whether the source has evidence or data supporting or challenging the study thesis, or
- if the concepts in the question are directly related to the source
The research question also informs you of the kind of sources applicable. For instance:
- Theoretical questions require scholarly articles.
- Policy-related questions require government or NGO reports.
- Historical analysis requires primary sources.
An effective research question is open-ended, specific, and significant to the field oof study.
Finding Credible Sources
Finding reliable sources is integral to producing informed and trustworthy research. The secret lies in discerning between credible and dubious sources. The strategies to consider when finding sources include:
- Understand types and hierarchy of sources. Differentiate between primary, secondary, and tertiary sources.
- Leverage library databases. Academic libraries have curated databases with scholarly books, peer-reviewed journals, and conference papers. Some of the digital platforms include PubMed, JSTOR, and IEEE Xplore.
- Explore institutional repositories. Repositories of theses, dissertations, and academic publications can offer valuable insights and perspectives.
- Cross-reference and mine citations. Examining references can help find additional reliable sources and uncover related research.
- Conduct expert interviews and surveys. These add depth to the research.
Evaluating Research Sources
Before you use a source, you should determine whether it has credible information. Not all sources that you find online are useful or accurate. Evaluating the sources is a critical step in your research process.
In the evaluation stage, you need to know how to recognize credible content, where to look, and how to cross-check what you get. Developing evaluation skills matters in your course as well as in your life.
Where to start in evaluating sources
The key factor when evaluating sources is to know the genre of your needed research. Follow the following criteria when evaluating sources to ease the location of what you need and to determine its credibility.
Criterion 1: Popular vs. Scholarly Sources
Sources are likely to be either popular or scholarly. Popular sources target a general audience. They are not peer-reviewed and do not include references.
Scholarly sources follow a strict publication process in which highly qualified researchers author them, and peer-reviewing follows. They include in-text citations and references at the end of the text. Scholarly sources include academic journals and books targeting specific audiences. Their authors mainly target other experts in their respective fields of study.
In this stage, these questions guide you to determine the source you are reading:
- Do the author/s include their credentials?
- Is the source peer-reviewed?
- What is the intended audience?
- Is there a reference list, bibliography, or works cited page?
The source is likely to be scholarly if fitting the above criteria.
The choice of sources depends on the topic. For instance, popular sources would suit when examining how different media outlets and social media sites portrayed a trade war. However, scholarly sources would feature when researching the effect of a particular therapy on diabetic patients.
Primary vs. Secondary Sources
A primary source provides a firsthand account of information. Autobiographies, government documents, diary entries, letters, works of art, statistics, data, and literature works are primary sources/. Newspaper articles by reporters from the source and social media posts also qualify as primary sources because they are firsthand accounts.
A secondary source is written after the event or seeks to interpret something after occurrence. For instance, biographies, data interpretation, and any content analyzing something or past events are examples of secondary sources.
Your research topic determines the number of primary or secondary sources to use. For instance, primary sources such as historical documents would be better when studying the history of the fishing business in the Gulf of America. However, secondary sources interpreting data and statistics suit when examining how advances in boating have altered fishing practices.
General Guidelines when Evaluating Sources
Once you identify whether a source is scholarly or popular and then determine if it is primary or secondary, you can proceed with evaluating a promising citation. The additional factors to consider when determining credibility are as follows:
- Find information about the author: Check the author’s background and area of expertise to determine whether they have experience on the topic.
- Read the abstract, introduction, and table of contents: Read these to know the purpose and depth of the source and to determine its relevance to your topic.
- Determine the targeted audience: Assess whether the vocabulary, tone, level of information, and authors’ assumptions about the reader are appropriate for your study.
- Establish whether it contains facts, opinions, or propaganda. This CRAAP criterion can help assess the nature and value of information. The relevant questions to consider here include:
- Currency – Is the source timely?
- Relevance – Does the source fit your needs?
- Authority – Who wrote the source?
- Accuracy – How reliable or correct is the source?
- Purpose – What is the purpose of the information?
- Establish if it uses objective or emotional language: Fact-based sources mainly include objective language. Propaganda and opinion-based sources are more likely to use emotional language.
- Evaluate the listed evidence: Evidence helps back up opinions.
- Cross-check the information: The credibility of a source increases if you can find listed facts or dates somewhere else.
- Examine the listed references: If the listed references can lead you to related material, this is a sign that the source is thorough and well-researched.
- Recheck the timeliness of the source. In some topics, sources are dated when new research becomes available. However, old sources would still be relevant if covering historical events. In assessing a source for timeliness, consider the following:
- When was it posted or published?
- Has the information been revised?
- Does the research topic require current information?
Going through all this can appear tedious and unnecessary, but the steps are helpful when seeking sources for your study report. Not following them can negatively impact your report and your credibility as a professional.
Ultimately, critical thinking should be at the heart of finding and evaluating sources. You should aim to be as rigorous as possible.
The authority, content, and purpose of a source should be clear before using it. Once you use a source in your paper, it either bolsters or undermines the credibility of your work.
Conclusion
Finding and evaluating credible sources is critical to the success of any research effort. Any credible research begins with a clear and focused research question that guides source selection.
It is necessary to understand different types of sources—primary vs. secondary, popular vs. scholarly— for credibility. Familiarity with academic databases, institutional repositories, and citation mining helps find quality materials.
In evaluating sources, the focus should be on assessing authorship, peer review status, relevance, accuracy, and purpose using tools like the CRAAP test. The source’s intended audience, language, and supporting evidence are also key credibility indicators.
Ultimately, critical thinking is crucial throughout the process of finding and evaluating credible sources.
